I am getting this validation error when using script task ??
Ah yes, you must have upgraded to Enterprise Edition 1.6.
One of the "undocumented features" of 1.6 is the ability to disable script tasks among other task types.
The settings that control this ability can be found in the activiti-app.properties file:
In your configuration you probably have the following set to true (it is set by default in 1.6).
Set these to false and you will be back up and running.
Also, be aware that whitelisting (beans and classes) are enabled by default so many of your integrations will likey fail.
The documentation of this feature was a bit later than planned but it is available here at http://docstest.alfresco.com/process-services1.6/topics/spring_beans.html and we are continuing to improve it.
