[Eugenia] FixGMFGen and nullpointerexception [message #677814] Thu, 09 June 2011 07:49 Go to next message
Eclipse UserFriend
Hi all,

I have the following code in FixGMFGen.eol:

var features = GmfGen!FeatureLabelModelFacet.all.select( feat |
feat.metaFeatures.isDefined());
var featureLabel = features.selectOne( x | x.metaFeatures.exists( mf |
mf.ecoreFeature.name == "qcf"));
featureLabel.println();

And it prints the following:
org.eclipse.gmf.codegen.gmfgen.impl.FeatureLabelModelFacetImpl@410e942e
(viewPattern: name={0} qcf={1}, editorPattern: name={0} qcf={1},
editPattern: name={0} qcf={1}, viewMethod: MESSAGE_FORMAT, editMethod:
MESSAGE_FORMAT)
So hopefully the query is correct...?

but somewhere else it crashes, see stacktrace below.
(Removing the code removes the crash..)
Any clues for this?

All the best,
Ivar Refsdal

PS...

This is also reproduceable on the model from
http://www.eclipse.org/gmt/epsilon/doc/eugenia/

and using the following code:

var features = GmfGen!FeatureLabelModelFacet.all.select( feat |
feat.metaFeatures.isDefined());
var featureLabel = features.selectOne( x | x.metaFeatures.exists( mf |
mf.ecoreFeature.name == "name"));
featureLabel.println();

Best,
Ivar

Hi Ivar,

The query is correct indeed. I've tried to reproduce this problem but haven't been able to. Could you perhaps provide more details about this (i.e. in which step does it crash? does it always crash etc.) so that I can investigate?

Cheers,
Dimitris
