Suggestions and Requests / #Object# macro for Model Search

« on: October 17, 2012, 07:57:32 am »

A number of times I've wanted to use an object's ID when composing SQL searches in Model Search. The latest is "Get all objects whose classifier is X", where X is an object selected in the model.

To be consistent with the use of #Package#, I think it would be appropriate to use #Object#.

I want to be able to do this:

Code: [Select]

SELECT s.Name as ClassifierName, s.Stereotype as ClassifierStereotype, s.Object_type as ClassifierType, s.Object_ID as ClassifierId,
f.ea_guid AS CLASSGUID, f.Object_Type AS CLASSTYPE, f.Name as Name, f.Stereotype
FROM t_object s , t_object f
WHERE
f.Classifier_guid = s.ea_guid
and
s.Object_ID = #Object#
Is this needed enough to make a formal request?

General Board / Oracle 11G as repository

« on: January 24, 2012, 05:35:42 am »

The EA Systems Requirements page shows the supported Oracle versiona as 9i and 10g.

We are running 11g, and our database support people don't want to run a down-level instance.

We have brought up a relatively small EA repository with Oracle 11g as the database.

We have encountered a problem where attempting to open a package results in a loop - CPU goes to 100% on one of the processors, and it continues to loop until you kill EA.

We are wondering if this is an EA-11g compatability problem.

So:

Has anyone else tried 11g? (I've seen other posts that imply this is so)

Are there known issues? Has the above problem been seen before?

Is there a timeframe for Sparx support for 11g?

Thanks,

Van

Bugs and Issues / EA - VC desynchronisation / package loss

« on: May 05, 2010, 03:38:31 am »

We are running EA 7.5 v850, MySQL database, SVN version control. We probably have 10 people working in one model, though usually only 2 or 3 at a time.

There are a couple of peculiar things going on, and I suspect they may be related.

1. One engineer said that a package he had been working in had disappeared from the project browser. I looked in subversion and found the package, and it showd him as having it locked.
At this point I attempted to reload the current project, which had no effect. The XMI file in Subversion was for the package in its initial state, apparently added to VC right after the package was created. He claimed to have checked it in after making changes, but I could find no evidence of that in subversion.
I checked a (full model) baseline that was taken a couple of days before and found the offending package, complete with contents.

2.On what I suspect is a related note, I've found a number of XMI files in SVN that are locked, but either the correspoding packages appear to be checked in (per the browser icon) or cannot be found in the EA project. I have been asked in several instances to help with people not being able to check out packages that they themselves had created - the packages showed as being checked in, but SVN said that the package was checked out. "Resynchronise with VC provider" does nothing to fix the problem - have to go into SVN and clear the lock, after which things usually seem OK.

I suspect a contributing factor is losing connection with the database when EA is open - the people who have this problem seem to all be laptop users, and I, with a desktop, never see anything similar happen when I've been updating things (I also check packages in religiously).

Has anyone else run into similar problems? Are there any suggestion on how to fix them? I've tried telling people to "check in your packages and close EA before you close your laptop", but the problems keep on popping up.

Thanks,

Van

Bugs and Issues / VC status problem

« on: June 09, 2010, 08:47:53 am »

EA 7.5 850

MySQL 5.0.37 community server

Subversion

CollabNet Subversion Client 1.6.4

Sequence of events:

Was looking at the ea repository t_package table with the MySQL Query browser, and noticed two checked out packages (as shown in the PackageFlags field)which were not visible in the project browser.

Executed File>Reload current project, and the two packages appeared.

When I right clicked>Package Control>File Properties on one of the packages, it displayed what I expected: the package was locked by the person identified.

When I did the same thing with the second package, I got a popup box

xxx\xxxxxxxx.xml: (Not a versioned resource) svn: A problem occured; see other errors for details

The t_package table XMLPath specified an existing file out in Subversion, which  indeed was checked out by the person indicated in the PackageFlags.

I executed the Package Control>Re-synch all statuses with VC providers.

When I re-ran the query against the t_package table, both CRC and the lock information disappeared, leaving only the VCCFG parameter.

The packages are still in the same statuses in Subversion, and (to my surprise) I still get the same results when I do Package Control>File Properties for the packages - one shows as being locked, and the other claims to not be a versioned resource.

The only additional factor is that I believe that the user's laptop has gone into sleep mode.

I will be submitting a bug report.

Bugs and Issues / SysML - how to get dashed controlFlow links

« on: February 02, 2010, 06:37:21 am »

Running 7.5.850, Corporate Edition.

When using the SysML Example Model, I can get a ControlFlow to appear as a dashed line by giving it a <<controlFlow>> stereotype.

In any other model where I create and use SysML ControlFlows (whether or not I have loaded SysML under Add-Ins), I cannot seem to get them to appear as dashed lines. There is no controlFlow stereotype avaliable, and the toolboxes available under MDG Technology for SysML (loades with the sample project) differ significantly from those available otherwise.

What would be nice:

• The ability to format a control flow as a dotted line. This is consistent with SysML 1.1.
• An example that was consistent with behavior outside of the example.

Does anyone have a technique for accomplishing the former?

Bugs and Issues / Model Validation - ObjectFlow to MergeNode flagged

« on: December 01, 2009, 08:19:33 am »

In a SysML 1.1 Activity Diagram, I have two ObjectFlows going to a Merge node that has a single outgoing ObjectFlow.

When I run Model Verification, I get the message "MRV05002 - error(<anonymous>(ObjectFlow)): ObjectFlow is not legal for Synchronization --> MergeNode".

This is a problem in a couple of respects.

First, the UML specification says:
Constraints
[1] A merge node has one outgoing edge.
[2] The edges coming into and out of a merge node must be either all object flows or all control flows.

Second, a Merge node does not do synchronization. A Join node performs synchronization, a Merge node does not. A Join node with ObjectFlow inputs gets a similar message, but the Join node definition says:
Constraints
[1] A join node has one outgoing edge.
self.outgoing->size() = 1
[2] If a join node has an incoming object flow, it must have an outgoing object flow, otherwise, it must have an outgoing
control flow.
(self.incoming.select( e | e.isTypeOf(ObjectFlow)->notEmpty() implies self.outgoing.isTypeOf(ObjectFlow)) and
(self.incoming.select( e | e.isTypeOf(ObjectFlow)->empty() implies self.outgoing.isTypeOf(ControlFlow))

So either a Merge Node or a Join node may have ObjectFlow inputs, but Model Verification flags them as errors. There are no additional restrictions in the SysML spec that affect this.

(EA version is 7.5.849, Corporate Edition)

I want to get other people to use Model Validation to clean up their models (and I'm considering augmenting the existing validation with add-ins to perform localized verification), but I need to make sure that validation behaves as it should before foisting it on others.

Has anyone else run into similar validation issues?

Van

Addendum: The problem seems to stem from a fork node (one ObjectFlow in, two ObjectFlows out) supplying one of the ObjectFlows to the merge node. I am in the process of checking out whether this is allowed UML.

Addendum 2: Figure 12.73 Control Node Examples (in the UML 2.1.1 Superstructure document) shows a ControlFlow from a Fork Node to a Merge node. Careful examination of the UML spec turned up no constraints that would disallow the same for ObjectFlows.

Uml Process / Types for Action Pins

« on: November 06, 2009, 07:30:07 am »

When I create an Activity parameter, I can assign a Primitive Type to it (Integer,Boolean,String,UnlimitedNatural).

If an action pin attached to a CallBehaviorAction is associated with a parameter of the called activity, I can see the pin's properties (inherited from the parameter) by right clicking on the pin (an Arguments popup appears).

If I create an activity diagram and attach pins to an atomic Action, I see how I can associate an Instance Classifier with the pin, but I don't see how I can associate a primative type. A pin is supposed to be a TypedElement, just as a Parameter is. Apparently all TypedElements are not created equal.

Or am I just missing something?

Automation Interface, Add-Ins and Tools / Package order using the Automation interface

« on: October 31, 2009, 04:26:48 am »

I am using Java to process a project, and I would like to retrieve packages in the order in which they occur in the Project Browser. However, when I use Package.GetPackages, the order is something other than that in the package Browser (whether I use  
for(Package subpkg: pkg.GetPackages()){... }
or
Collection p = pkg.GetPackages();
for(short i=0;i<p.GetCount();i++){
Package subkg = p.GetAt(i);
...}

The RTF reports write out packages in the Project Browser order, so I assume there is some way to do it.
