[news.eclipse.tools.ve] Re: Another NPE and VE won't display my composit

Hi Joel,

From your description I have tried to re-create the error you got but 
don't have enough information for me to encounter it.  Could you please 
post an idiot proof description of how to get the error, e.g.

1 - Open file foo.java
2 - select the lines 30 to 40.  Cut and paste these so they are at line 20.
3 - Close the editor.
4 - Clean the project
5 - Re-open and see the VE crash.

Also post the full source code of the file(s) in error.  Don't include 
that much narrative of why you are doing what you are doing with moving 
the code around. To create a bug report all we need is a set of 
re-creatable steps from a standing start where we can make it crash and 
then see what's wrong.  If it crashes it's a bug.

By the way - there are two bits of parsing that go on with the VE when 
you edit source code.  One occurs each time you change the source and is 
a snippit reload that tries to do intelligent delta on what has changed 
into the model.  If this can't do its job (which sometimes legitimately 
occurs if the sippit analyzer realizes the changes made are too big to 
delta in) then a full reload occurs.  You can trigger this at any time 
by pushing the pause button at the top and then unpausing.  Each time 
the VE closes a file and re-opens it we used to always re-parse from 
scratch the source, however now we have a cache that holds information 
that helps performance.  This cache is what is cleared by doing a 
Project>Clean.

Best regards,

Joe Winchester
