How to retrieve data from different entities and display in one form and then use a common update to update the data in different entities

[Ritesh K Kaushik]

Ofbiz uses different update buttons to update data in various entities. My requirement is to have a common update button to update data all the different entities.  i.e. getting the function of different update button in one button ( i.e. invoking one service which internally invokes multiple services.)

 Any help is appreciated ..
