Open Source Document Management System | OpenKM

Hi guys,
Can you explain me why i cant access to classes or methods outside of GWT based classes for example classes inside com.openkm package in GWT based classes ? I know that gwt based classes compile to javascript codes but don't know why we cant use other packages inside them.
So, how we can communicate with other classes inside gwt baseed classes ? for example i want to run a automation action when user clicked a button inside a custom tab in tab document ?

Im using openkm-6.3-CE in OVA mint environment

Might be you should start reading the GWT documentation and what does this framework. A good starting point in your case might be http://www.gwtproject.org/doc/latest/Re ... ation.html ( what JAVA classes are emuled by default by GWT and what not ... hope that will give you some clue about how it works the GWT JAVA to Javascript engine )
