EPIC Not working with specific files

I am trying to open files with .html extenstions.  The files have a combination
of perl, html and mason.  I have done this previously with EPIC 0.3.0 and
Eclipse 3.0.2 with0out any problems.  However, I have upgraded to WDSC version
7.0 with Eclipse 3.2 and EPIC 0.4.28, and now I am getting the following
error:

Unable to create this part due to an internal error. Reason for the failure:
An unexpected exception was thrown.

If anyone can help. Please let me know.

I am surprised that you are attempting to edit HTML with EPIC - there must
be better tools for that? Anyway, maybe I can reproduce the problem if you
send me a sample file which causes the exception to occur.

manitoulin wrote on Mon Apr  2 20:18:30 MEST 2007:

The file has HTML in it, but is mostly perl.  I use the EPIC editor because
it works well with perl, and handles the html okay.  There is usually limited
html in the files.  I can certainly send you a file, where do I send this
to?

I tried the file you just sent in Eclipse 3.2 / 0.4.28 (I don't have access
to WDSC). It does not look very pretty, but it does not cause any NullPointerException
either, so I cannot reproduce your problem. If you can debug EPIC yourself
(as described at http://e-p-i-c.sf.net/devguide/devguide.html), it would
be helpful to know what is passed as argument "type" to PerlPresentationReconciler.attr
before the NullPointerException occurs (I suspect that the line with int
index = ((Integer) textAttributes.get(type)).intValue(); is where the NPE
occurs).

I have tried to follow the steps to debug, but I am unsure if I did it correctly.
 However, the property Type indicates that the value File.

What really seems strange here is if I take the exact same file I sent to
you and change the file extension to anything other than .html or .htm (I
tried .mas) then the file opens perfectly fine.

jploski wrote on Tue Apr  3 15:50:04 MEST 2007:

You mean it opens fine with the EPIC editor after changing extension? If
you want *.html or *.htm to open the same way as *.mas, that should not
be a problem. All you have to do is edit "File Associations" in Preferences
and set up *.htm(l) to be associated with the same editors as "*.mas" there.

manitoulin wrote on Tue Apr  3 15:54:35 MEST 2007:

I have already set file associations.  *.htm, *.html, *.htm(l), and *.mas
are all set to use Epic by default.  I did this before even trying to open
any files.

jploski wrote on Tue Apr  3 17:22:47 MEST 2007:

Try 0.4.29. It likely won't fix the bug (well, it works around the NPE),
but it should provide more information in the Error Log which you can post
here.

manitoulin wrote on Wed Apr  4 15:22:16 MEST 2007:

Well EPIC 0.4.29 now allows me to open the file without the java error.
 However, the colors that define areas do not appear.  It looks like the
code was opened with NotePad.  If I change the extension of the file to
.mas, or .xyz (I can change to almost anything), the file opens fine, no
errors, and the colors are visible.  

I also get the following error in the error log almost every 3 seconds,
when opening the file with .html extension.

Thanks, that info is what I wanted to see. Now upgrade to 0.4.30 to see
if it is fixed there.

That fixed my issue.  Thank you so much for your assistance.
