ForEach properties 'start counter value', 'final counter value' and 'completion condition' are unsigned-integer-
expression as per the bpel spec. Right now clicking on the property opens a dialog window with a text box. Any integer 
constant or expression has to be entered manually.

The enhancement request is that the user be allowed to use the mapper to be able to create expressions for unsigned 
integers and/or assign a constant value.

Steps to get to the afore mentioned dialog box.
1. in the bpel editor create a bpel process with a forEach structured actvity.
2. right click on the forEach construct and select properties.
3. click on the button next to any of the above mentioned properties and a dialog with a text box appears. This should 
be a mapper window so that the user can create an expression using it.
