Hello Rob.

I'm trying to save a programatically created bpmn2 model exactly like the modeler generates the file.

The easy solution would be to use the Bpmn2ModelerResourceFactory but in a stand alone mode (that is similar to the modelreader example) it requires too many modeler dependencies to be practical.

Therefore I have been looking into the save options of a emf model and got completely lost.

First: all bpmn elements that the bpmn2 model does not recognize gets save with prefix of my target namespace. Example:
<bpmn2:itemDefinition id="ItemDefinition_1" structureRef="sapprop:sflight"/> with sapprop being my target namespace in lowercase. I found a save option that prevented this and then lost it again in all my crazy testing..

Second: the structureRef above gets saved with full document reference whereas in the modeler resource implementation a custom xml handler is used. I wish to use that handler is stand alone, ie for save option OPTION_URI_HANDLER.

So could I be guided out of the forest to generate programatically the same output as the modeler produces?

Many thanks!
Martin

Hmm, the only thing I can suggest is to look at the Bpmn2ModelerResourceImpl class. I have found that, for me, these XML OPTION_ things are a matter of trial and error and their behavior can only be fully understood by debugging deep into the EMF code Sad

Also, if you have defined a default namespace (i.e. <definitions xmlns="com.sap.mynamespace"...>) it will affect whether NS prefixes are generated or not.

Sorry I couldn't be more help, but a lot of this EMF parsing and serializing is "black magic" to me Wink
