Hello, I'm using Workspace from the communitypack. When trying to load a component, just when calling this.deliverComponent(),
// do the remote API call
this.deliverComponent(serverParams, function(e) {
if (Ext.getClass(e) == Ext.direct.ExceptionEvent) {
}
}, this);
More details in the following screenshot:

Then in the console window I get the following message: <h1>
NameError
in NetzkeController#direct
</h1>
<pre>wrong constant name usuarios_grid_crud_usuario</pre>
If you need more information in order to try to reproduce this exception, please tell me.
I hope somebody could help me.
Best Regards!
