Improved: Use FlexibleStringExpander in form widget lookup field field
target parameters
(OFBIZ-11418)
Changed target-parameter attribute of the form widget's Lookup field to
use the FlexibleStringExpander type rather than String. This has been
done to allow reference to other form fields which may have had their
parameter-name attribute set to a FlexibleStringExpander expression.
