SWT Visual Editor not showing correctly [message #900196]

Hello,

I have eclipse Juno installed under oracle jdk 1.7.0_05 in Bodhi Linux, and the visual editor does not seem to work. The steps I took were just upgrading windowbuilder, and installing the SWT toolkit.

Then I create a new SWT/JFace Java Project and adding a new Shell, and open the "Design" tab. An error is then shown that disallows the editor to be used (I uploaded a screen capture with the exception shown in the error log).

Just in case, the message in the event details is:

Designer [1.5.0.r42x201206111201.201208051011]: org.eclipse.wb.internal.core.model.creation.ThisCreationSupport cannot be cast to org.eclipse.wb.internal.core.model.creation.ILiveCreationSupport

The Stacktrace:

BootLoader constants: OS=linux, ARCH=x86_64, WS=gtk, NL=es_ES
Framework arguments: -product org.eclipse.epp.package.java.product
Command-line arguments: -os linux -ws gtk -arch x86_64 -product org.eclipse.epp.package.java.product

I've tried to reinstall eclipse and Windowbuilder several times, to no avail. Any clue?

Thank you (sorry about my english, I'm spanish), and keep the good work!

It looks like an installation problem of some sort. It would be helpful to see the entire Eclipse .log file.

What exact Eclipse distribution are you using?

Is the Eclipse PDE installed? Several of the exceptions indicate that it might be missing (it is required for SWT/RCP editing).

Hello,

I've installed the last version of eclipse Juno (4.2) for Java developers, that includes the WindowBuilder feature. I've tried to install PDE, but eclipse says it is already installed. I attach the complete log of a simple test.

Thanks for your answer Smile

Hello all,

I've been trying with other distributions of eclipse and windowbuilder to no avail Sad

So far, I've tried Eclipse Juno 4.2 JDT and Classic and Eclipse Indigo JDT and Classic. In the classic edditions, I've installed Windowbuilder from scratch, and in the JDT editions I tried upgrading (after confirming the error persists).

Somebody else has this kind of problem?

Regards,
