Hi,

Im working on an editor that is to aid in helping the creation/edition of XML documents.

Unfortunately, so i have learned, i will have to deal with EMF xsd-importer generating FeatureMap objects.

For example in my model i have a OBAFunctionControl object, which has references to a mixed type, which can be FormatPN, FormatSN.

The OBAFunctionControl will get two ELists in the java code, and a EFeatureMapEntry list, aka the featuremap.

As far as i know, there is no way for eclipse sirius to make use of the featuremap objects to determine the true order (i.e. merge the lists).

I am willing to modify the Eclipse sirius source code, in order to add support for EMF feature maps, but i do not know where to start.

I believe i need to look into org.eclipse.sirius.tree and org.eclipse.sirius.tree.ui.

I was wondering if someone with some more knowledge of the codebase could give me some directions, i am only interesting in implementing this for the tree-diagram option of sirius atm.

Hi,
You can, maybe, use a java service to get the list you desire and use this service in the "Semantic Candidates Expression" of the TreeItem mapping under "OABFunctionControl". It is a proposition, I have not tested it.

I have considered this, but how would you be able to determine the order of different types of sub-nodes (such as FormatPN, FormatSN) under some tree node?

Is it possible to mix these nodes with a semantic expression?

Hi Rick,

If you define a mapping for each type of sub nodes, you will not be able to mix sub node types under some tree node: the result will be sorted regarding the order of mappings and then the order of the semantic candidates expression evaluation for each mapping.

If you want to mix every kind of sub nodes, you might define a mapping with a domain class on a common super types, and use the semantic candidates expression to order the result as wanted.
