You need to install the BPMN editor - the easiest way to get this editor is through the JBoss Tools update site, referenced on this page: http://www.jboss.org/tools/download/stable/3_2_GA in the SOA Development category, in the BPMN Feature.
I don't believe the meta model and diagram format are standard in BPMN1, only the graphical grammer. So not interchangable. This will be addressed in BPMN2 which will hopefully be supported in Savara in the near future.
Ah - I didn't try to use Eclipse to view the .bpmn_diagram file. I see now it is associated with an Eclipse viewer. Is this an IANA Internet Media Type, or just an Eclipse-ism?
Now I can view it. Thanks.
I get the error message:
Description Resource Path Location Type
The gateway should have a default gate to ensure that at least one gate will be valid at runtime. PurchaseGoods_PurchaseGoodsProcess.bpmn_diagram /Clearing ca:CreditAgency::<Activity> BPMN Specification
Why is it necessary to produce this error?
No IANA internet media type, this is just the particular representation used by this Eclipse.org implementation.
There are a few issues with the current export - one being that occasionally gateways are generated with only a single output, and therefore unnecessary. As this export format is being removed in favour of BPMN2, no additional work has been put into resolving these issues at the moment.
