Revision 1866380

Implemented: Service parameter default-value attribut can support flexible string
(OFBIZ-11180)

When you define a service with default-value, you can't set simple dynamic resolution for the value.
The improvement extend the default-value attribut on service parameter to support the FlexibleStringExpander syntax and realize the expand on service context.

Example :
     <service name=createPicklist default-entity-name=Picklist engine=entity-auto invoke=create auth=true>
        <auto-attributes include=pk mode=OUT optional=false/>
        <auto-attributes include=nonpk mode=IN optional=true/>
        <override name=statusId default-value=PICKLIST_INPUT/>
        <override name=picklistDate default-value=/>
     </service>
