Hi Collin,
Hi Collin, I am using SmartGWT with GWT but the rpc call is
made using GWT. None of the collections work during this call, its not just
the linkedhashmap. Please let me know how do i get you the " http payload"
logs for you to dig further.
Connections is a typo, as you caught right its collections.
am not doing any custom serialization unless you call, implementing the
interface IsSerializable. I am trying with my whole project. I am making
plenty of calls by passing collections across RPC but only this call is
failing. As i said eariler, i started getting this error with the newer
version of gwt. I moved from 2.6.1 to 2.8.1.
Please let me know, which logs you need to dig further
Client Calling code
navigationServiceAsync.saveUserAlertValue(usrStgyValVO,userId, new
AsyncCallback<String>() {
@Override
public void onSuccess(String result) {
destroy();
command.execute();
SmartLoadingPopup.showAlert("Alert Saved !!", result);
}
@Override
public void onFailure(Throwable caught) {
caught.printStackTrace();
//console.log(caught.printStackTrace());
}
});
