ClassCastException in ValuesManager.addMember()

[harsha.galla]

Isomorphic,

I also tried to use 3.1d -( Isomorphic SmartClient/SmartGWT Framework (SNAPSHOT_v8.3d_2012-07-10/Enterprise Deployment 2012-07-10) ) libraries in our project but have some irrelevant errors as below:

In the above I see the following line: ' SmartClient/SmartGWT Framework is already initialized'.

does this indicate any potential issue.


The same code works absolutely fine with 3.0.

Thanks.

We've moved this to a new thread, it looks unrelated to the thread you posted in.

We'll check on whether a problem has been introduced with this method.

[Isomorphic]

This method appears to be working normally and we can't see a way for a ClassCastException to occur. What are you passing to addMember()?

[harsha.galla]

Isomorphic,

We are creating a ValuesManager and addMember adds a dynamicform to it.

Thanks.

[Isomorphic]

That's definitely not enough to reproduce a problem on it's own. Can you try to isolate why this is happening?
