How about the user.d2wmodel file? Have you looked at that? That
should contain all the modifications you've made with the assistant,
and having a clean project that works makes me thing maybe it is the
culprit.
The *.d2wmodel files are the other key piece (beyond the model) of a
Direct-To project. The combination of it the two file types control
almost everything. Errors in these filea can also cause many hard-to-
trace problems.
With RuleEditor deprecated, you can use the Rule Modeler (http://
webobjects.mdimension.com/wonder/RuleModeler-latest.tar.gz) that is
part of Project Wonder. I have not used it yet, so you're on your own
getting it setup. But that may help you find problems with
your .d2wmodel files, just like Entity Modeler is great for tracking
down problems with an .eomodel file.

Calling D2W experts,
Dave, thanks for this tip, there was one model warning which I have
removed, but same result.
However, by creating a new D2W project in WOLips based on the same
model I have banished the crash.
What I am unsure about is how to transfer my customisations from
the original D2W project. If I try to use the D2W assistant by
clicking on Customize, I get:
java.lang.IllegalArgumentException: WebAssistant: You backtracked
too far
Is this assistant a thing of the past?
If so, how do I manually configure D2W field sizes. I have an Edit
text field that is way too small and need to make it bigger.
Thanks

Hi John,
I don't know about DTW as I haven't ever used it, but I use D2JC
every day (for now, migrating to pure Swing). D2JC is VERY VERY
VERY sensitive to having the EOModel be _PERFECT_, and I found
that 90% of the issues I'd have with D2JC were problems with the
model.
Before I migrated to Xcode, I used to open my model in Entity
Modeler just to get the better validation. It helped a LOT. Listen
to it. I don't know if it will fix this issue, but it can save
hours of frustration for many other problems.

Hi WO Dev List,
We have moved several apps to Leopard/WO5.4 successfully (not
D2W), but we have one D2W application which produces the
following exception when a search of some data is triggered
by clicking on a Search button in the app. As D2W is 90+% WO
doing its magic stuff, I am not quite sure how to track this
problem down. Can anyone advise on why there might be a cast
class exception of NSMutableArray within eoaccess when DTW is
running a query? This worked ok pre-WO5.4.
