mwe2 reference workflow

Question

When you start a new Eclipse IDE and create a new MWE2 workflow you can reference workflows from plugins in the target environment or workspace (within new RCP)

component = @foo.MyWorkflow {}

But this doesn't works for all workflows, some aren't resolvable:

Couldn't resolve reference to Module 'OtherWorkflow'.

Even when copying MyWorkflow, renaming to MyWorkflow2 and restarting the RCP: MyWorkflow2 isn't resolvable.

edit: must be some kind of problem of the xtext referencer, after some time without any changes, also other workflows can be resolved, but after deleting the workspace of the RCP they re-disappear edit2: appears like a bug in 2.3.1, with latest nightly (pre 2.4) all workflows can be resolved

Answer 1

First: The @ notation does not require a second eclipse instance. The editor and tooling also resolves in the same instance.

Second: The mwe2 builder is not very reliable. Have a look at the hidden bin folder within your project space. The builder should copy and update your mwe2 files in this location. It will only reference files that are present and up-to-date here. I found that I often had to touch the source files to force a rebuild, or to delete the target files to get rid of a stale state that was not recognized.

Otherwise mwe2 is a sparsely charted meta-black hole. You have your wits. Good luck.
