Hi,
I am not sure if this is a defect, but I would be interested in knowing why this is happening.
I have two XText 1.0.2 installations set up. One with XText 1.0.2 SDK, and one with just the XText 1.0.2 UI installed.
I have set up two target definitions in my environment. One that points to the SDK, and the other, just the UI and the runtime.
I targeted my environment to the SDK target definition. I launched a second Eclipse. When I invoke content assist, things are ok here.
Next, I re-targetd my environment against the XText 1.02 UI definition. I rebuilt everything. I launched with the same workspace against the UI definition.
When I invoke content assist at the same location, I got the following error. It seems to me that the configuration data in my workspace is corrupted. If I clear the configuration data before I launch, content assist works again.
I am wondering if there is some class mismatch between the two packages? I have seen similar problems in a real "install" environment. And I trying to find out what could be a possible cause for this.
Thanks...
