Smart GWT V4.0, IE11

Issue 3:
I am using a dynamic form which is added to a SectionStackSection. A ToolStripButton named “save Button” is added to that SectionStackSection. Whenever user click on that button saveData() method of DynamicForm class is being invoked.


Code module is given below:

SectionStackSection sectionAttributes = new SectionStackSection("Section Details");
DynamicForm form = new DynamicForm();
form.setDataSource(DataSource.get("<<crosssectionDS>>"));
ToolStripButton saveButton = new ToolStripButton();
saveButton.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
form.saveData(new DSCallback() {

// code snippet

});
sectionAttributes.addItem(form);
sectionAttributes.setControls(saveButton);

In the <<crosssectionDS>> DataSource Class we have implemented Update() method.
public class CrossSectionSummaryDS {
public DSResponse update(DSRequest dsRequest) throws Exception
{
// code snippet
}
}


Now the Issue is we did not get any response from Data-Source implementation class.
We are using GWT 2.6.1(using gwt-servelet.jar,gwt-dev.jar), Smart GWT 4.0 (smartgwt.jar, smartgwtpro.jar),and Internet explorer 11.
Previously it was working fine in IE8, IE9 with GWT 2.3.0, smart gwt 3.0. The above codes are running fine in IE8. We are upgrading the above mentioned jars to run this application in IE11.

Note: if anyone need any information further, please reply.
