java.lang.NullPointerException when creating new item in GWT

[havernas]

Hello.

I have a problem with GWT Designer 6.9.1 and Eclipse 3.4 with GWT installed.

When I want to create a new item thanks to the GWT designer, Eclipse throws me an exception and the file created is empty.

From where this error come from ? Thank you for any answer.

All the best.

It appears to be a bad installation as GWT Designer can't find one of its own files.

[havernas]

I've deleted all files and directories where name begins by "com.instantiations" and "com.swtdesigner" in feature's and plugin's directory of Eclipse, and I've installed the last version for which I have a licence (6.9.1), and the error still persist. The others designers work great, not GWT.

What version of GWT are you using (as specified in your Designer > GWT prefs)?

GWT Designer v6.9.1 only supports GWT 1.4.62 and 1.5.3.

In order to use GWT 1.6.4, you need to be using GWT Designer v7.0.

[havernas]

Effectively. I use GWT 1.6.4.

Is the licence in WB 6.9.1 works with 7.0 ? If not, is there promotional offers for upgrade ?

Thanks.

As long as your support is current, you can use any version that you want.

[kenferguson]

I've hit a similar problem whenever I try to create a new object in GWT Designer. The error I get is copied below.

I've tried several uninstalls/reinstalls of GWT Designer via the Eclipse Software Update section - but that only allows me to uninstall GWT Designer and NOT Designer.

Any ideas of next steps? I've got too many other plugins installed to blow away the whole Eclipse install.
