Suggestions and Requests / Re: Need: Category (Tagged Value Type)
« on: September 05, 2018, 01:18:26 pm »
My point was that multi-select tagged value types aren't a good idea. Shape scripts were just an example of how they are unsuitable.

I would recommend anyone implementing a profile away from RefGUIDList for the same reason. You can't reliably/easily determine the reverse relationship when it's a list. You can see an example of that in the traceability window. It offers the ability to show tagged value references, but it can't do that for a RefGUIDList. The performance would be an absolute killer on any non-trivial database.

Your category tagged value would suffer the same problems if you wanted to use it to drive reporting or similar.

Out of curiosity, is there a reason you are encoding a static list of categories into your categorisation instead of modeling them? These days I almost always prefer to define something in the model where possible so that it's self-documenting and easily extensible.

I would strongly recommend using multiple enum tagged values instead.

ie. Each one is a single value in a 0..* list.

In general it's more flexible and powerful. Even if we do need to add improved capabilities to query for multiple values in places.

As an example, I know you use shape scripts. At a guess, you're probably wanting this so a shape script can print out multiple values. But it actually means that you can't decide to convert that into decorations or similar in the future.

Using multiple tags, it would by possible to update HasTag to query on multiple values. (If it doesn't already) There's also no reason why we can't extend the syntax to get the list of values in a print (optionally specifying a separator)

Something like this:
Code: [Select]
shape main
{
  rectangle(0,0,100,100);
  print("#TAGS:category#");
}

decoration Val1
{
  if(hasTag("category","Val1"))
  {
    setfillcolor(255,0,0);
    ellipse(0,0,100,100);
  }
}
decoration Val2
{
  if(hasTag("category","Val2"))
  {
    setfillcolor(0,255,0);
    ellipse(0,0,100,100);
  }
}
decoration Val3
{
  if(hasTag("category","Val3"))
  {
    setfillcolor(0,0,255);
    ellipse(0,0,100,100);
  }
}

You need to use is null in conjunction with the left join.

Automation Interface, Add-Ins and Tools / Re: Uml to typescript
« on: August 30, 2018, 10:10:39 am »
I don't know much about typescript, but usually the time is more in learning how to use the grammar and code templates.

Generally I'd estimate 1-2 days for 90%+ coverage in code templates. For a grammar I'd say 1-2 weeks for 90%+ coverage, although that varies a lot more depending on what kind of language documentation exists and how much of the syntax can legally appear at the file/class level vs inside operations only.

It's displayed in the top right of the EA window in EA 14.1

General Board / Re: Protobuf .proto generation from a class diagram
« on: August 28, 2018, 09:23:34 am »
Looks equivalent to xsd, json schemas etc. You could generate it using code generation templates. I'd also consider the API for the schema composer.

Like Geert, I'm not aware that anything already exists.

BPMN2.0::Activity (UML::Activity) --> so UML::Activity is the base-type - this sounds logical
Actually, action would be the closest mapping to UML. A Process should be mapped to Activity.

BPMN2.0::Pool (UML::ActivityPartition) --> UML::ActivityPartition - but WHY??
Probably because it had the closest appearance.

Those mappings come from when EA was less flexible with profile customization than it is now. But they aren't as important when implementing a profile to represent a completely different metamodel.

How can I generally extract the base-UML-types for any Element? Is there a SQL solution?

The only trick is that the EA search window will helpfully show you the metatype that comes from the stereotype. If you want the base type you need to go around it.
Code: [Select]
select Object_Type as Real_Type from t_object where <condition>

Unfortunately, this is a Windows issue.

If you want to know the details... EA declares itself as single DPI aware. What that means is that EA is only expected to handle a single DPI scaling for a session. It is Windows responsibility to scale any API functions that involve window/screen dimensions when they apply to a monitor with different scaling from the default.

Unfortunately, there appears to be some situations where Microsoft didn't get that right. One is the rendering of the non-client area (outside edge) of windows on secondary monitors. This impacts the visual styles that draw a colored glow around a dialog or floating window. Other times the windows themselves don't get scaled correctly. Unfortunately, EA itself can't detect that you are using multiple resolutions. Windows tries to protect it from the information that it declared it can't handle, so the results of the APIs to detect that kind of thing are fabrications.

The only other option is for EA to declare itself as fully DPI aware. But the impact of that is that we need to rescale everything dynamically as you move windows around etc. For now that's not feasible, so we're left with the behavior you have seen.

Bugs and Issues / Re: Notes for class attributes
« on: August 20, 2018, 10:34:59 am »
Jules, my comment wasn't intended to be offensive in any way.

I acknowledge that the attribute list, attribute properties and attribute notes were previously all in the one dialog. EA 14 is a little different, you can edit the properties and notes for attributes in the same windows that you can edit the properties and notes for anything.  So, you can select an attribute in the project browser, diagram or the attribute list and edit it in the same place you would edit a class. You'll also get a number of extended dialogs depending on the type. That unification of where to look was the intended improvement.

Having said all of that, as discussed already in this thread, version 14.1 offers an option to access the old dialog. So there's your alternative.

What's missing is an option.

General Board / Re: Aggregates connector is shown the wrong way around
« on: August 15, 2018, 09:21:41 am »
Fortunately there used to be a flag in the preferences (Pref's -> Links -> Association default - source --> target) that allowed to swap (i.e. correct) that behavior.
That flag is still there but in the v13.0 and also 13.5 this flag has apparently no effect, i.e. that connector is shown the wrong way round, regardless of whether that flag is checked or not.
The option changed the drawing direction, but EA still placed the aggregation at the same end. It has less effect these days because the quicklinker provides options to be explicit about the drawing direction. If you drag an aggregation from the toolbox it still uses that option.

Bugs and Issues / Re: v14 long lasting bugs
« on: August 14, 2018, 10:05:59 am »
Yes, it is, but for v14. It doesn't work for v14.1 beta
In EA 14, open the about dialog. It tells you when your activation code is valid until. I'm guessing it has expired.

Your query is being sent to Oracle (or at least the Oracle OLE DB Driver) unmodified.

You can't please all the people all the time.
No, but I am interested in improving EA.

I'm guessing that the issue is that the previous dialog for attributes contained the attribute list, properties editor and note editor. Those are now three separate windows, although each of them is used in more contexts than just editing of attributes.

Bugs and Issues / Re: EA Cloud Connection Problems with https over IIS
« on: August 13, 2018, 01:38:06 pm »
I'm by no means an expert at IIS, but I've configured the IIS integration a few times, mostly by trial and error before the current documentation existed. There's an amazing number of things that can go wrong with this. It's much easier to configure webserver configured into the cloud service itself.

You only need the http module or the isapi module. Both are ways that you can configure a mapping for a particular request to go to a dll.

If EA gets a 404 message from IIS, it's because a request for /sparxcloudlink.sseap returns 404. If you get this, it suggests that the handler mapping isn't correctly configured because it isn't even trying load the module. The error messages from misconfiguring the module itself should be different.

Once you've got that, you need to edit sparxcloudlink.sseap in the same directory as the module dll so that it can be read. There should be different errors returned if there are bad values in that file.
