JavaScriptException: (null): null on adding records to TreeGrid

[jrich]

Hello,

We are using Smartgwt SC_SNAPSHOT-2012-02-23_v8.2p.

Since downloading this version we have been having problems with our Trees.

Even though the tree is set to be editable double clicking on a node now has no effect, we can't edit any of our tree.

On adding a record we get the following error:

00:46:25.172 [ERROR] Uncaught exception escaped
com.google.gwt.core.client.JavaScriptException: (null): null

at com.google.gwt.user.client.rpc.impl.RequestCallbackAdapter.onResponseReceived(RequestCallbackAdapter.java:232

If we use exactly the same datasource and data a ListGrid works perfectly.

The record is added and the database is updated it fails here

finally {
      Object returned = (caught == null) ? result : caught;
      boolean toss = statsContext.isStatsAvailable()
          && statsContext.stats(statsContext.timeStat(methodName, returned, "end"));
    }

in the onResponseReceived method of the RequestCallbackAdapter class resulting in the exception.

If you have any ideas or pointers as to why our trees are no longer working we would be very grateful.

Kind Regards
Jeni
