Error when testing Connection of Global Element in MuleStudio

Question

I'm using MuleStudio 3.4 and have a simple Flow with a Drupal Connector. The Configuration for this Drupal Connector comes from a Global ElemCent Configuration.

But when i want to test the connection from the Global Elements Properties Window, i get the the message:

Test Connection failed: Invalid Global Element. Cannot access the Global Element to test. java.long.Throwable

Here is the Configuration XML:

Answer 1

just make sure that you are persisting this information in mule-app.properties. Otherwise you can create another property place holder and after referencing that you can go ahead and use.
