Unable to load 'super' class in Desinger View

[colinzhao]

My gwt application project depends on another project (a base project) where I have a set of base classes to be shared by other projects. One of the classes there is a BaseComposite which extends the GWT Composite and is subclassed by my application Composite classes.

This works fine until this past week when I upgraded my Eclipse, GWT and Designer to

Eclipse 3.5.1
GWT 1.7.1
Designer Version: 7.2.0 Build id: 2009.11.18

The application till runs in Eclipse, but I get the "unable to load 'super class' when I switch to designer view on any of my Composite classes that extends the BaseComposite. Designer viewer works for subclasses located in the project of the BaseComposite, but not in a different project.

Somehow, Designer is not able to load the class:

[Eric Clayberg]

Are there any errors in your .gwt-log file?

Please post a small, self-contained test case that will reproduce the problem.

[colinzhao]

The log is attached. Apperantly, GWT Designer has trouble to load the BigDecimal class in the base project, where I use the gwt-math module that emulate the BigDecimal.

Unfortunitely, I cannot reproduce the problem with a small project. It only happens with my application project.

Note again, the project compiles and runs fine. The problem shows up only when I switch to the design view of a composite that extends the BaseComposite in the base project.

Could this be some kind of class loading problem with the Designer?

There was no log attached.

Apperantly, GWT Designer has trouble to load the BigDecimal class in the base project, where I use the gwt-math module that emulate the BigDecimal.

No, GWT Designer does not have any trouble doing this. We tried it on our end, and it worked just fine.

Unfortunitely, I cannot reproduce the problem with a small project. It only happens with my application project.

Sounds like a problem with your application project. Again, if you want to send us a test case that will reproduce this, we would be happy to take a look.

If you can't reproduce it in a small project, you should focus on what is different between the two projects.

Could this be some kind of class loading problem with the Designer?

Possible but unlikely (as it would have likely shown up with many other users already).

Again, we would need to see an actual test case to confirm this as a GWT Designer problem or not.

The problem is resolved. It is my own problem that the project contains two GWT modules. One of them doesn't list all the inheritance modules. While I switched to designer view, the IDE was trying to load the wrong module. That caused the problem. Everything works now after I deleted the wrong module.

Thanks for you help.

Glad to hear that the problem is resolved. We would definitely not have guessed that without a test case!
