ADF: Converting Number to Integer using EL

I spent about 20 minutes looking for this solution today - so I figured I'll just post this entry as a future reminder for myself...

I was using a Web Service data control that has an Integer parameter, and I wanted to get the value of EmployeeId from an ADF BC based ADF Faces table into it using an af:setProperty tag, but I got an error because the engine couldn't convert the jbo Number type to the needed Integer type.

Something like: 

Cannot convert 203 of type class oracle.jbo.domain.Number to class java.lang.Integer

Turns out the solution is quite simple, add a .value to the end of the Number field EL.

So instead of 

                  <af:setPropertyListener from="#{row.EmployeeId}"
                                          to="#{bindings.EmployeeId.inputValue}"
                                          type="action"/> 

use something like:

                  <af:setPropertyListener from="#{row.EmployeeId.value}"
                                          to="#{bindings.EmployeeId.inputValue}"
                                          type="action"/>

And the conversion just works.
