Seems like no one else is doing this kind of thing, which is strangeto me because I find it really useful. Those interfaces eachrepresent a CRUD type action that can be taken on an entity from a webapp. When I put the controller class together I just tag it with theproper interfaces, fill in a few missing details like the query toperform, and the ITDs take care of the rest in a standard way.Without ITDs I'd have to have a huge superclass that contained all theaction methods, even the ones I don't want, or a ton of smalleractions which would have a lot more trouble sharing state and couldn'tas easily be introspected by the view components to do cool thingslike automatically display the proper buttons for each availableaction. I guess I could also simulate multiple inheritance but thattakes a lot more code and makes referring to "this" a lot morecomplicate than it should be.


But I digress.....


I created bug #292429.  Let me know if you need anything else.

Now *thats* what I call a type declaration :)

Can you raise a  bug for this Dave?  With your diagnostics I may be
able to get to the bottom of it - I know I certainly don't have a
testcase with a declaration like that!

I spoke too soon, it just happened again. I checked the eclipselog fileand I think I've found the additional information you wereexpecting. This
time it is a generic class being woven:

public class JobManagementAction implements SearchAction<JobListing>,
       SelectAction<JobListing, Long>, CreateAction<JobListing>,
       UpdateAction<JobListing>, DeleteAction<JobListing>,
       SuppressAction<JobListing, JobListingSuppression>

And here is the info from the log:

The exception would appear to occur for an ITD on a generic typewhere

It is attempting to identify the actual occurrence ofparameterizationin the target type so it knows what the type variable should bindto.
If the ITD is

List<Z> SomeInterface<Z>.foo;

and the generic declaration is

class Clazz implements SomeInterface<String> {
}

then it is looking for SomeInterface in the Clazz hierarchy - so it
knows Z is String for the new member in Clazz.  For some reason it
doesn't find SomeInterface in the Clazz hierarchy (is it perhapsbeing
declare'd parents'd in? that would be pretty advanced)
The exception is thrown with some text to give us moreinformation, I
wonder why you don't see it...

I don't expect that it will be a continual problem, but thoughtyou'd
like
to take a look into the cause.
I've also noticed that incremental compilation often seems to notupdate
the
markers in the IDE until I've done a full rebuild. Several timesI'vedeployed code from a project with no markers only to have it failwith anexception when running that is equivalent to what the build errorwas.After a clean/rebuild the appropriate error shows up inEclipse. Any
recommended steps for debugging that?
