Workaround or Fix for AssertionError on create new project?

Hello Sam,

Use the File | Invalidate Caches to rebuild the filesystem cache. Then the
error should go away.

When creating a new project with EAP 9647 and 9720 (and I believe
intermediate versions as well), I obtain the assertion error at the
bottom of this message.

Also (not confident this is related), if I try to open a pre-existing
IPR attached to an IML/IWS, the IPR content disappears and Idea is
unusable (project view shows up empty, and no paths can be added).

Also, I've seen this problem noted on JIRA in a few places, such as
here, still listed as open.
http://www.jetbrains.net/jira/browse/IDEADEV-31468

I'm anxious to get the EAP working, since the new Scala plugin
requires 9634+. Please let me know if there is a workaround I can do
to get around this on my end, or if I can provide more information (I
posted to Exception Tracker, but not sure how to find it.)

Thanks,
Sam Reid

Thanks very much for your prompt attention to this severe problem.  Below follows my log that inicates my use cases for (1) a related existing problem (2) creation of a new project <fixed> and (3) loading af an existing project <fixed>.  Let me know if you have any questions or comments about this.

download and install #9728
Create new project
No module
Finish

(1) New project doesn't open; no exception is thrown.  This seems problematic to me.

File->Invalidate Caches->Restart Now
Create new project->From Scratch->Next
Uncheck create module->Finish

(2) new Project structure dialog appears

File->Close project
Open existing project->select project

(3) pre-existing project opens and works properly without mangling IPR or IML files.

Thanks again,
Sam Reid

Hello Sam,

problematic to me.

I don't quite understand what you see as a problem here. If you create a
project and choose not to create a module in the Project Wizard, you're supposed
to see the Project Structure dialog. Is that what happens?

The major problems are all resolved for me.  The remaining problem occurred before I cleared my filesystem cache.  The problem was that when I pressed "create new project" and followed the wizard, after "Finish" the new project did not appear; instead, the welcome screen stayed up, as if I had not created a new project at all.  This was a similar error as before I cleared my filesystem cache, except this time there was no Exception dialog, and no "!" on the bottom right to indicate what error had occurred.

Thanks,
Sam Reid

Hello Sam,

Ah, I see. The exception reporting is disabled in build 9728 (as in all release
builds), so the exception did happen but you didn't see the red exclamation
sign.
