InvocationTargetException - can't edit module in designer

Postby kgt » Tue Jan 30, 2007 6:16 am

When I try to use the design view of my GWT module, I get a pop-up warning box:

com.swtdesigner.properties.PropertyException: java.lang.reflect.InvocationTargetException

Contact support by email now?


Design view of all other composites works fine. The error appears to be related to one of my remote service interfaces (CompanyList). There doesn't appear to be an error in the module itself - my code compiles and runs fine.

Results from log:

Re: InvocationTargetException - can't edit module in designe

Postby Eric Clayberg » Tue Jan 30, 2007 6:48 am

The problem is caused by the reference to the RemoteService which can't be instantiated at design time.

See this forum thread for a solution.
