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
John

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.
