GWT JavascriptObject ClassCastException in GWT-2.6.1

[pioneer.suri]

We are working with the Web application which was developed by using GWT and smart gwt project. Currently we are using
GWT-2.5.1 and smart gwt-5.0 in our application.Now we wanted to upgrade our smart gwt upgrade to 6.1 from 5.0 but not changed the GWT.

We got the compilation error with smart-gwt-6.1 with GWT-2.5.0. So we also migrated GWT to 2.6.1. Now we are able to compile our application successfuly.

We have got the runtime exception like below.



public void transformResponse(Object data) { // data contains json string
JavaScriptObject jsObj = (JavascriptObject) data.// This line causes the below excepton
}

ClassCastExcetion: java.lang.Strig can not cast to com.google.gwt.core.cient.Javascript Object.

This code was working with the earlier versions of smart-gwt and GWT. but now it is throwing this exception.

Firstly I was not be able to find any documentation about compatability of smart-gwt and gwt.

Could any body tell me how to solve the above issue and how to handle this upgrade of smart gwt.

Please see the FAQ for the information you need to include when asking for help with a JavaScript error.

In addition to this, we obviously need some basics for this particular case, like what kind of DataSource this is and the DataSource definition.

As we mention in the SuperDevMode help topic, GWT 2.6.x is the minimum supported GWT version for SGWT 6.1p.
