Bugs and Issues / Failed BPMN XML export
« on: May 28, 2015, 11:25:37 pm »

I'm attempting to export a BPMN model (diagram + nodes) using the BPMN 2.0 XML format. For this project, Activities have been documented using the "Linked Docs" so we currently have a rather large amount of data in the DB.

The XML file that's produced is only 1KB with the following content:
<?xml version="1.0" encoding="windows-1252"?>
<bpmn:definitions id="EAPK_A431E0CA_4860_4305_BDF5_B180510055C1" targetNamespace="" xmlns:ssbp="" xmlns:bpmn="" xmlns:xsi="" xmlns:di="" xmlns:bpmndi="" xmlns:dc="" exporter="Enterprise Architect" exporterVersion="11.1.1113"></bpmn:definitions>

I wonder if the Linked Document information interferes with the export module.
I tested it with EA 11.1 (1113) as well as the latest EA12 build with the same outcome.

Any idea?


Bugs and Issues / SVN Version control issues
« on: October 16, 2014, 07:38:25 pm »
I'm aware that many people have dropped and discourage using SVN + EA due to a number of issues.
As I have a number of customers that need the "Undo Check Out" feature to roll back, and since EA security feature doesn't fulfil this need, I currently have to keep this configuration. (if someone has identified an alternative to VC that provides a rollback/undo feature, I'm interested!)

I was wondering if there is any recommendation to avoid the following issues when using a central DB (SQL Server) coupled with SVN:
A number of users have experienced a desynchorisation between SVN and EA i.e. we can end up with an empty controlled package that cannot be checked out since the SVN lock remains on the repository, yet not seen by EA. Hence I have to run an EA/VC resync, followed by an undo check out so it all comes back to normal.

Worse case: a user had a number of uncommitted changes in the central DB and a desync between EA and SVN occurred ; the package was locked in EA so he could no longer update his package. Running a resync from a different user reloaded all data from the XMI and deleted the uncommitted changes !  :-/ I take that this would have been prevented if it had been run from the same user.

What is Sparx view on these ongoing issues between EA and VC repositories? Is there anything planned in this area?


Bugs and Issues / BPMN2 glitches
« on: October 09, 2014, 01:29:34 am »

I found two glitches on a BPMN2 diagram:
- I'm showing the events and activities on the subprocess itself (there's no composite diagram) and I often get the option IsExpanded re-enabled when I move things around (when I want to leave this disabled)
- I copied the diagram to a word document with an event triggered subprocess (triggeredByEvent = true) i.e. it's got a dashed border -> the rendering in the pasted image contains errors


Bugs and Issues / Search results with Packages : issue
« on: July 25, 2014, 11:34:42 pm »

I've created a custom search (SQL) using the Builder.
here is a simplified version to test :
SELECT ea_guid AS CLASSGUID,  name as Package from t_package

I use CLASSGUID so that EA can find my Package in the Project Browser.
However when I right click on a result from the list, Find in Project Browser is disabled.
This is odd since the keyboard shortcut Alt-G works... I can also access the Package's properties when I double click onto it.

Is this a bug?

Bugs and Issues / EA Crash with Postgresql project
« on: July 12, 2014, 12:14:28 am »
One of my customers needs to move an EA project to a PostgreSQL DB (Linux server).
The DB and tables have been created, ODBC connector installed (psqlodbc_09_03_0210) and configured (as per Sparx instructions), and a connection has been defined with EA.

When connecting from EA, the following pop-up screens come up :
1. Database Connection Error : reopening connection to database
2. Enterprise Architect has experienced a network error and will shut down.

Finally EA shuts down / crashes.

As I successfully set up an EA project on a Linux PostgreSQL DB before, I'm running out of options on getting this one to work.

Any hint on what might be going wrong here?


Bugs and Issues / VC Check Out deletes elements from diagrams
« on: June 18, 2014, 08:34:18 pm »
We're working on a large EA project hosted on a SQL Server DB, coupled with an SVN repository.
Elements are stored in a different package tree than diagrams. When I run a check out on the parent controlled package where both elements & diagrams are stored, I often get elements removed from my diagram (the link between elements still exist) !
This seems to be a result from a number of operations done by EA by comparing the XML content with the db content during the Check Out.
This can damage users confidence in the tool due to unwanted modifications on the model when running a check out.

Is there any recommendation to prevent this scenario?

Bugs and Issues / Add relationships from element browser bug
« on: April 17, 2014, 08:42:13 pm »

I use the Element Browser to add relationships from a class that is selected from the project browser onto a diagram (none of the associated elements e.g. 2 classes are on this diagram). This works well.
I attempted to do the same with ports (child element of a SysML Block); I'm getting an odd result i.e. the relationship is added to the diagram without any element (as they weren't on the diagram).
Could this be fixed so each missing port and blocks are added ?


Bugs and Issues / EAP to DBMS Project Transfer crashed
« on: March 13, 2014, 09:03:15 pm »

I tried to transfer an EA project stored in a local EAP file to a MySQL DB using the Project Transfer feature.
As I have quite a lot of Linked Documents, the data in the t_document table is rather large I guess. After a couple of minutes, I get the following error message:
[MySQL][ODBC 5.2(w) Driver][mysqld-5.6.-16]Lost connection to MySQL server during query [Select * from t_document] field: docdate.
Press OK to continue to next row (this record will be lost). Cancel to abort.

Having clicked on OK, this error is followed by an EA crash (runtime error).

Do I need to change any settings in the MySQL ODBC connector or in EA to get this transfer to work?


Bugs and Issues / EA hangs / crashes when the DBMS is down
« on: March 20, 2013, 07:10:25 pm »

We worked with a shared EA project on a SQL Server DBMS.
Since yesterday evening, the DBMS seems to be down. That makes EA crash (EA not responding) and the user experience is quite bad.
Couldn't this be fixed in EA so it displays an error message to the user and stops attempting connecting to SQL Server?
It seems EA attempts forever to connect to the DBMS.


Bugs and Issues / SD Interaction states Bug
« on: February 29, 2012, 02:29:55 am »

I'm using interaction states in a sequence diagram to show when an object's state changes following receipt of a message.

I noticed that all interaction states are not stored in the diagram itself as expected (similarly to notes) but in the package that contains the diagram (having moved the diagram to a different package)
So if I move my SD and all UML elements to a different package and delete the original package, I lose all my interaction states!

This bug was found in EA 7.5 but also in EA 9.2

This is a scary bug ...!
Best way to resolve by Sparx is to materialise interaction states in the project browser (like fragments, endpoints, etc.)

Bugs and Issues / Scenarios in v8: step to extend an existing UC
« on: February 16, 2010, 04:03:02 am »

When entering steps for a use case scenario, you have the option to "Link the Step to Use Case" as specified below in EA help:

Either include the actions of an existing Use Case element, extend an existing Use Case element, or invoke a Use Case as the action of the selected step [...]
The appropriate includes, extends or invokes stereotyped connector is created between the current element and the selected Use Case

It looks like the extend association is created the wrong way round;
if you specify that a use case continues to another use case with an extends association, the extends association should be from the other use case to this one, as it is the other one that extends it. Otherwise it should provide the "Extended by" stereotype instead (less used though)

Bugs and Issues / use case structured scenarios in v8.0
« on: February 16, 2010, 03:42:39 am »

I started testing the Structured Scenarios for a use case (new Scenarios tab in the use case, or also accessible via new Scenarios and Requirements view) in EA v8.0 beta 1.

I have 3 questions so far:

1 - Scenarios embedded in use cases
Use case scenarios are embedded in the use case element and it does not seem feasible moving them from one use case to another.
As an example, if you started writing a few scenarios and then found out you specified it in the wrong use case, is there any way you can move some or all your scenarios from one use case to another?
Since we can produce an activity diagram from a scenario, it looks like a scenario is modelled in EA as a set of activities (steps) so similarly to an activity diagram and its activities that can be moved from a use case to another (or other similar classifier), I'd expect we can do the same with scenarios.

2 - Linked requirements properties not shown
If your use case has a realization association with one or several Requirements, the "Linked Requirements" is populated accordingly in the Scenarios and Requirements view.

Unfortunately the requirement's properties such as the content of the notes remains empty - you have to double click on the Requirements element to view the properties; this seems to be a bug.

3 - Profiles and scenarios
When creating a new scenario, we currently have 3 types to choose from (Basic Path, alternate, exception). EA accepts new types to be entered which does the trick if you use other types.
Is it however possible to extend scenarios properties using EA Profiles? I tried extending the use case metaclass but it doesn't have any scenario property. I cannot find any scenario metaclass either.
Are scenarios specific to EA and hence cannot be extended via Profiles and stereotypes?

Thanks in advances for your answers.

Bugs and Issues / Alternate paths in v8.0
« on: February 16, 2010, 10:02:27 pm »

I specified a basic path scenario for a use case and a couple of alternate ones.

I can associate an alternate or exception path from a Step that belongs to the Basic Path scenario, but not from an alternate path!
I find this very restrictive. See the example below that is perfectly valid, yet I cannot specify it in EA.

Basic Path
Step 1: [action]
Step 2: [action] OR A1
Step 3: use case end

Alternate A1
Step 1: [action]
Step 2: [action] OR A2
Step 3: use case end

Alternate A2
Step 1: [action]
Step 2: [action] OR Basic Path
Step 3: use case end


Bugs and Issues / Activity Notes not shown on diagram
« on: February 13, 2009, 11:07:23 pm »

I'd like to display the notes captured in an activity on the Activity Diagram.
I enabled Notes from the Features Visibility > Show elements compartments but with no luck
Also tried the diagram's properties: Elements > Show compartments : Notes enables

it works with States so I'm wondering if this is a bug??


Bugs and Issues / EA crashes when saving a constraint in a class
« on: January 16, 2009, 02:22:51 am »
I'm often encountering the issue that EA crashes when saving a an invariant constraint within a class.
It especially happens when the length of the constraint is fairly long.
