Hello,
I'm playing with mwe/xpand in an attempt to generate simple xsd from ecore. The thing is working well already when invoked from Eclipse (right-click on xsd.mwe and executing it as a MWE Workflow).
My problem is that I've made a plugin which provides an action which invokes this xsd workflow on a selected ecore file. The problem is that the action is invoked, workflow is started but then it halts for about 2 minutes and then continues. During 2 minutes halt I don't see any huge memory allocations, or heavilly reading from disk or a lot of CPU consumption. Nothing. It (eclipse process) shows just very little activity at all. My code from action looks (f is selected IFile):
mon.subTask("Generate XML Schema for " + f.getName() + " model ...");
IPath model_path = f.getFullPath();
String wfFile = "workflow/xsd.mwe";
Map<String, String> properties = new HashMap<String, String>();
IPath src_gen = f.getParent().getLocation();
properties.put("src-gen", src_gen.toString());
properties.put("model", model_path.toString());
StringTokenizer tok = new StringTokenizer(f.getName(), ".");
String name = tok.nextToken();
String xsdFileName = name + ".xsd";
properties.put("xsdFileName", xsdFileName);
Map slotContents = new HashMap();
WorkflowRunner wrun = new WorkflowRunner();
wrun.run(wfFile , null, properties, slotContents);
f.getParent().refreshLocal(1, null);
I've stripped debug messages out. The output of workflow run invoked by this action then looks:

Please see especially timing on those two lines:

INFO: Registering platform uri '/export/home/karel/usr/local'
Mar 8, 2012 8:51:57 PM org.eclipse.emf.mwe.core.container.CompositeComponent internalInvoke
My question is: is this a know issue? If so, then is there any known fix or workaround for this. If not, then is there any way how to turn more verbose debugging on workflow so I can see more messages from it and judge better where it halts for those 2 minutes?
Thanks!
Karel

Hi Karel,
The StandaloneSetup will scan the subdirectories of the platformUri path for .project files. Usually the "platform path" should point to your workspace directory, so there is a limited number of directories to scan. In your case it is
'/export/home/karel/usr/local'
and I assume there a LOTS of directories in the deep file system hierarchy.
So move your projects to a better location, use this as platform path and it will work faster. You could also subclass StandaloneSetup and register this in your workflow to make it more fitting to your situation.
Regards,
~Karsten
