Lavanya,
In order to use bindings of a PageDef, that PageDef must have been loaded first. If you navigate from the UserProfiles page, that page has loaded the UserProfilesPageDef. To force loading the UserProfilesPageDef on other pages, you can set a parameter in the other page's PageDef:
<parameters>
<parameter id="bindingContainersToPrepare" value="#{'UserProfilesPageDef'}"/>
</parameters>
JHeadstart looks at the parameter bindingContainersToPrepare and ensures that they are loaded when you run the page.
You can add such a parameter by going to the target page's PageDef, and in the structure window right-click the 'parameters' folder, and choose 'insert inside parameters' -> 'parameter'.
Don't forget to uncheck 'Clear Page Definition before Generation' for this group (you can find it in the Application Definition in Expert Mode), otherwise your changes get lost when you run the JHeadstart generator.
Hope this helps,
Sandra
