Description of problem:

Following the E2E Yahoo UDF Test Script, I tried to create the UDF. When I got to the part to create the return parameter for the function the "Add" column button could not be enabled.  

Version-Release number of selected component (if applicable):

DV 6.0.0 ER4
JBDS 7.1.0 CR1
JBIS 4.1.3 Beta5
Teiid Designer 8.3.0 CR1
OS X 10.9

How reproducible:

Happens every time.

Steps to Reproduce:

Using Designer:

1. Create a new relational model
2. New Child > Procedure > User Defined Function > OK
3. Enter a function "Name" and a "Java Class" (to get rid of error message) 
4. Click the "Result Set" tab
5. There is no way to add a result set column

Actual results:

Unable to create a return parameter for relational UDF model. But the model can be created and the return parameter can be added later using the New Child menu option.

Expected results:

The "Add" button in the wizard should enable so that a return parameter can be entered.

Additional info:

None
