Activiti_Explorer not refreshing menu entries as expected

Hi I have an issue with Activiti-Explorer and I hope someone can help. Firstly Acitiviti's a great product and well done to all those involved in the dev' of the s/w. However I have an issue that I'm unable to fix within the Activiti-Explorer web application regarding the refreshing of tasks queue

First of all, activiti is a developer-platform and the Explorer-app is an app demonstrating the usage of the full Activiti API. The queued menu's are not altered after task-operations, only the assigned and involved tabs are. Pressing F5 doesn't refresh the list, as Vaadin caches the widget-state on the server. When changing page, this list is refeshed again.

We opted for this strategy (not refreshing queued) as this can be a heavy query to perform on "every" operation you do in the UI. You can, off course, alter this behavior in the app yourself to suit your needs…

Ok, got it. Thank you for your reply.

… Update…
After downloading the Activiti-Webapp-Explorer2 source code and adjusting to get the desired behaviour I thought I'd post back to let anybody else who may be interested know where to inject the code within the application to gain the functionality as described in my earlier post.

taskPage.initUi();

In my case I wrapped the call to refresh inside a function that filtered whether or not the refresh actually needed to take place.
If anyone's interested the following is an overview of code within the application, what to look for and where I placed the code to refresh the menu bar


package org.activiti.explorer.ui.task;
public class TaskDetailPanel…
  …
  protected void initTaskForm() {
    …
    if(formData != null… ) {
    @Override
    protected void handleFormSubmit(FormPropertiesEvent event) {
      …
     taskPage.initUi(); // *** new injected code ***
    }
  } else {
    …
  }
}

Anyway, great job. And thank you for your advice and prompt response.
Regards
JK

The refresh button on some place on gui would be (imho) better solution, to avoid the "automatically" refreshing after "every" operation.
The current solution is realy not optimal ops: An user of this web applicarion just click on entries to perform the operation and amazes, because no operations to do…
