Hi THanks for the reply. does it mean i need to change <parent-ref>default.default</parent-ref> <if-exists>overwrite</if-exists> to <parent-ref>default.default</parent-ref> <if-exists>keep</if-exists> i have read in the tutorial Instructs the portal to overwrite or keep this object if it already exists. Possible values are overwrite or keep . Overwrite will destroy the existing object and create a new one based on the content of the deployment. Keep will maintain the existing objct deployment or create a new one if it does not yet exist. what i understand is, if i make changes in one portlet and the <if-exists>keep</if-exists> then hte changes will not be affected as keep will maintain hte existing object. please help me with my doubt.
