NullPointerException when making a Reload

[fabio_bellocchio]

Hi,

please, has anybody already faced this problem:

When you make a Reload+Rebuild, the following error appears in the "tasks" view:

Description: Web Dynpro Generation: Generation aborted with exception null (java.lang.NullPointerException)

In the Java view the error is pointed on the file Licitacoes.wdcomponent.

But apparently there is nothing wrong with the project.

In the tasks view, the "location" column (that should inform the line where the error has occured) is blank.

Maybe somebody can help!!

Thanks.

Fabio

3>types_compilation in DC caf/runtime/uicoupling/api (CAF domain)

4>caf/runtime/uicoupling/api/lib (CAF domain)

5> mail – SAP-JEE

6>External in caf/eu/gp/api (CAF domain)

Thank you, Mithu.

In fact, I've found all of the DC's, but the "mail – SAP-JEE". Please, could you give me a hint about where can I find it?

Thanks

Open the Eclipse view "PDE Runtime -> Error Log", There you should find the stacktrace. Can you post that?

Hi Armin,

First there is a big "stack trace", that starts with: "com.sap.ide.webdynpro.generation.util.viewset.ServiceViewSetGeneration.cleanTemplateViewInstances(ServiceViewSetGeneration.java:161)".

And following, 4 identical messages:

"Error Jun 02, 2007 19:41:16.521 Jun 2, 2007 7:41:16 PM com.sap.ide.metamodel.core.service.ObjectCacheManager.fas... [Thread[main,5,main]] Error: found new MDO: //WebDynpro/Controller:br.com.copasa.licitacoes._LicitacoesViewSet_LicitacoesObras_LicitacoesWindow"

Do you think it may have something to do with the Java version? (it's 1.4.2_12)

Thank you!

Fabio

I propose to open an OSS message on BC-DWB-WD-JAV.

Hi Fabio,

It is a general error from Developer Studio. If you close and open you developer studio, this error will go.

Sometimes such error comes because of OutOfMemoryException.

So don't worry about this error.
