GWT Designer problem on OS X

[sawan]

Hello,

I'm having a problem opening a GWT client interface file in the "design view".

I'm using Eclipse 3.5 on MAc OS X 10.6, GWT SDK version is 1.7.1.

Attached is a screen shot of the error.

I have tried re-installing the plugin and that didn't help. Re-installing Eclipse didn't work either.

Can anybody please help?

Further update on this:

The designer refuses to open up for files generated by the GWT SDK 'webAppCreator' utility. I have managed to get the design view working with creating the project in Eclipse as a
'Window builder GWT Java project' and then having the SDK utility overwrite the files. Refreshing the project brings in the new files and 'design' does the right thing.

What do you mean by "the designer refuses to open up"? Please be specific.

Also, it is always a good idea to start with the docs...

Hi,

Thank you for taking the time to reply.

The attached screen shot should show you what I mean. When I click on the 'design' tab of the GWT client interface, I get that error.

For now I have managed to get that part working, however there seems to be a bug in the JVM that causes GWT 1.7.1 on JDK 1.5 OS X to not work properly.

The suggested fixes don't work out for me.

It's not clear to me what error you are getting as your prior message stated that you "managed to get the design view working".

Your most recent message did not include any attachment.

It would be helpful to see your Eclipse ".log" file and the project you are having a problem with.

Hi,

Please find the sample project attached (war/lib has missing JAR to get around forum file size limit).

I suspect this is not an Eclipse/GWT Designer problem rather it is some bug caused by a combination of sing older GWT (1.7.1) on OS X 10.6.

Below is the error I get when I run 'ant -debug hosted' in the project directory.

Thank you.

I tried your project, and it worked fine on my end.

I did not see anything GWT Designer related in your last post, so I am still unclear on what issue you want us to help you with.

Again, it would be helpful to see your Eclipse ".log" file showing any GWT Designer related issues.

[sawan]

Sorry, are you using Eclipse 3.5 on OS X 10.6?

If you are having general issues with GWT under OSX, you should address those to Google's GWT forum.
