Jdev 11g: HumanTask Compliation Issue

If you auto create , Human Task Form using Auto-Generate Task Form jdeveloper automates lot of stuff. A new Project is created with lots of artifacts, and a task form is created too. Jdeveloper even creates a deployment profile.

So you happily, first deploy the Composite, and then deploy the Adf project containing the task form.

But when you are deploying the task form application , a compilation issue comes..

Error(86,53): The function "getResourceValue" for prefix "wf" can not be found in the specified tag library.
Error(90,56): The function "isCustomActionAvailable" for prefix "wf" can not be found in the specified tag library.
Error(96,53): The function "getResourceValue" for prefix "wf" can not be found in the specified tag library.
Error(100,56): The function "isCustomActionAvailable" for prefix "wf" can not be found in the specified tag library.

Solution is to add a jsp tag library. Workflow Tags 1.0
