M2Doc and PVMT extension

[Fabio_Guarita_old]

Hi, I am trying to get M2Doc to generate documentation of custom PVMT add-on model properties.
I applied the following properties to ComponentExchanges as seen below:
I want to be able to display the contents of the string “description” on the generated doc.
I was able to access its value through the follwing aql query in Sirius interpreter:
aql:self.eAllContents(fa::ComponentExchange).eContents().eContents()->select(x | x.name = ‘Description’).value
but, whenever I try to access the feature “value” in the template like this:
it returns the following errors:

Just adding to this, I wanted to be able to reach the values of enumeration too but I’ve come to this point where it seems I can’t go on without getting the value from the applied properties.

You are collecting all elements at de depth of 2 and some of them don’t have a feature name (see error message for the list). You probably need to do something more specific.
You will need to select the extension of the corresponding type for PVMT:
myComEx.ownedExtensions->filter(PVMTPackage::PVMTType).description
you can use the .eClass() service in the interpreter to find the appropriate type. Select the extension and use “aql:self.eClass()”. If you want to know the list of features you can use “aql:self.eClass().eAllStructuralFeatures”.
You should also add PVMT metamodels to your template properties.

Hi Yvan,
I found a different solution (actually I believe it falls in your solution but is more specific). It was described in a topic on the old Forum (link below).
Too bad I wasn’t able to find it there before. I searched it but I only found it today by reading each post until finding the answer. I’ll leave the link so others can use this solution as well.

Hi,

Since the link provided by Fabio_Guarita_old is not available anymore, I can suggest this solution.

The query

aql:self.eAllContents(fa::ComponentExchange).eContents().eContents()->select(x | x.name = ‘Description’)

return objects of type AbstractPropertyValue that doesn’t have feature named “value”.

Since “Description” feature is a StringProperty, you have to convert the result in StringPropertyValue before :

aql:self.eAllContents(fa::ComponentExchange).appliedPropertyValueGroups.eContents(capellacore::StringPropertyValue)->select(x | x.name = ‘Description’).value

Kind Regards
