Description Miles Parker

2011-01-14 16:20:25 EST

I've seen some strangely intermittent -- that is, never consistent enough to report -- issues with performance and parsing of my cross-project XPand and XTend files. Sometimes I get into a state where dependent artifacts will not resolve and/or xtend markers will not go away. Often this seems to happen after there have been a number of very long xtend/xpand analyze jobs. But this last time I'm getting some errors which might be helpful.

First, I'm having cases where I get the "did you forget to configure" error and the type is completely nonsensical. i.e. I don't have a type "SPr". This looks like some kind of corruption to me:

EvaluationException : Couldn't resolve type for 'SPr'. Did you forget to configure the corresponding metamodel?

Comment 1 Miles Parker

2011-01-14 16:26:00 EST

OK, I missed something really obvious. Somehow -- due to an accidental edit presumably -- I really did try to use a bad type there. So pls ignore the first issue.

But on second issue, there does seem to be something going on with creation of markers.

Comment 2 Miles Parker

To avoid confusion, I'm going to mark this one invalid and create a new bug for the marker issue.
