Hi,

I have a problem using fragments. I am using Gendoc 0.5.1 with Papyrus 1.1.0 on Eclipse Mars.
I used the following code to print the documentation/ comment of a package:
[for (p:Package | self.ownedElement->filter(Package))]
1 [P.NAME/]
[for (co:Comment | p.ownedComment)]
<dropEmpty>[co._body/]</dropEmpty>
[/for]<drop/>

[/for]
I tried to move the 3 lines printing the comments to a fragment:
<fragment name='displayComments' importedBundles='commons;gmf;papyrus'>
<arg name='element' type='uml::Element'/>
[for (co:Comment | element. ownedComment)]<drop/>
<dropEmpty>[co._body/]</dropEmpty>
[/for]<drop/>
</fragment>

And then use this fragment in the main code:
[for (p:Package | self.ownedElement->filter(Package))]
2 [P.NAME/]

[p.displayComments()/]

However, I got the following errors:
The execution of a script failed: Error during generation of Gendoc script :Invalid Type: Comment
Unrecognized variable: (_body)

What did I do wrong?

Thanks and regards,

Marc

Fragments appear to be a bit temperamental somehow...
Do you try typing "co" with uml::Comment ?

Thanks, adding uml:: in front of Comment made the trick.

Best regards,

Related question:

when using the fragement as above:
[for (co:Comment | element. ownedComment)]<drop/>
<dropEmpty>[co._body/]</dropEmpty>
[/for]<drop/>

When there are several comments, they appear to be in the wrong order: comment2, then comment1.
Any way to make them in the right order?

Thanks,

Marc

The point is that ownedComment is not an ordered collection... So you will have to use another trick, again! Wink

Here is mine:
* add an ownedConstraint to the element owning the comments you want to order and give it a specific name (e.g. "_OrderedComments")
* using the contrainedElement (which is ordered) refer to the comment in the requested order.
* Use this constraint in your loop (you can use a filter on the name) rather than the ownedComment.

This is a bit cumbersome but it works and this the best I found so far.

another solution is to define / use a sort method based on eContents, if I remember well you can do this kind of operation :

[comment Order a sequence according to containment order of the Eobject, works well if all the eobjects in the bag are contained in the same object /]
[query public sortedByContainmentOrder(arg : Bag(ecore::EObject)) : Sequence(ecore::EObject) = 
self->sortedBy(
  e : ecore::EObject | e.eContainer().eContents()->indexOf(e)
)/]


We should add this query in common gendoc bundle
