I'm noticing that my debugging sessions become compromised... in
particular when the tracing has to pull up a new file, I'll get an alert
with the following message:
'Debug Source Display' has encountered a problem. Error
Details: Error
and the font in the new tab that contains the file being traced becomes
black and the trace arrow disappears. I seems that if I click the
'step' button enough times, the debugging trace makes it out of the
'black font' tab, back to a normally decorated tab where tracing appears
normal.
I see error messages in my log that look like this:
!ENTRY org.eclipse.ui 4 0 2008-07-14 23:47:08.980
!MESSAGE Unhandled event loop exception
!STACK 0
org.eclipse.swt.SWTException: Failed to execute runnable
(org.eclipse.wst.sse.core.internal.util.Assert$AssertionFail edException:
release was requested on a model that was not being managed)
at org.eclipse.swt.SWT.error(SWT.java:3777)
Any ideas?
Thanks

If you do a step and it steps over multiple lines then it could be that php has compiled those lines
out (eg forming part of a single statement) and it then breaks at the next compiled line.
As a simple example consider this script
<?php
$a=1;
$arr2 = array (1,
array (2,
array (3,
array (4,
array (5,
array (6,
array (7,
array (8)
)
)
)
)
)
)
);
$c=3;
?>
when you step through this it stops at the $a=1, $arr=, $c=3 lines and skips the ones inbetween.
This is because php has compiled lines 3-17 as a single line at line 3.

One thing I discovered with nfs is that there is the option to cache
changes on the client... I'm not sure how well integrated Eclipse is
with nfs, but I set nfs to update file changes on the server immediately
as I think the server files should be updated as soon as the changes are
made from the client.
Also, as for the error conditions popping up during the debug sessions
that lead to the undecorated unresponsive tab, I found that if I close
the tab and re-open the file from the explorer, the debug session
continues as normal on the newly opened tab...
So it looks like it the tab properties are compromised during the
stepping process such that the user can't see the xdebug action.
