grid store update event fails

[Kalle1985]

Hello,

since i updated my GWT 1.7 project to GWT 2.0.4 the listener of my store won`t work.

Here is the snippet code:

 
store
.addStoreListener(new StoreListener<AttributeValueModel>() {
 

@Override
publicvoid storeDataChanged(StoreEvent<AttributeValueModel> se) {

//Do something...
}
});

Is there a certain reason?

Be aware that, since you are now using Gwt 2, you have also to use the GXT version release for GWT 2.
Make sure that is the case.

Thank you for reply,

i allready displaced the old gxt.jar with the new one.

The store should listen to changes (when a new resultset was loaded).
Is it actually a change or update event?

Well, actually, probably you should then take a look at the storeAdd method of the listener.
This is fired when records have been added to the store.

Ok,
that`s a good suggestion! "storeBeforeDataChanged" works also fine.

You are using a Loader? DataChanged would a fire after a successfull load. Try to add a Loader.LoadException event listener to your loader and see if there is any exception.

If you use RPC, make sure you also updated your gwt-servlet.jar on the server.

This is what i`m doing:

 [...]
RpcProxy<List<AttributeValueModel>> proxy =
new RpcProxy<List<AttributeValueModel>>() {
 
@Override
protectedvoid load(Object loadConfig,
AsyncCallback<List<AttributeValueModel>> callback) {
CognosLdap.cognosLdapAdministrationAsync.
getUserData(userId.getRawValue().trim(), new AsyncCallback<List<AttributeValueModel>>() {
 
@Override
publicvoid onFailure(Throwable caught) {
getMessageBox("Fehler", caught.getLocalizedMessage(),
MessageBox.ERROR, MessageBoxType.ALERT, null, null);
}
 
@Override
publicvoid onSuccess(
List<AttributeValueModel> result) {
store.add(result);
}
});
}
};
[...]

You should not use that code at all when using a proxy with a loader. Pass the callback which you get in the load method to your service.

Also that code would fire a Store.Add event.

i did that in the past but after the migration to GWT 2.0.4 this approach won`t work!
So in my trouble i changed the code to that what you can now see.

Have you listened to the loader.loadException event of the loader? Is that firing?
