Applies to:
Oracle WebCenter Portal - Version 11.1.1.3.0 to 11.1.1.3.0 [Release 11g]Information in this document applies to any platform.
Symptoms
When attempting to access a page created with the WebCenter Page Service, the following error occurs.
ERROR
<MetadataResourceXmlImpl><parseBeans> ADFc: Duplicate managed bean definition for 'task_flow_action_bean' detected.
<UIXRegion><getRegionModel>
java.lang.IllegalStateException: The expression "#{bindings.pagecreatepage1.regionModel}" (that was specified for the RegionModel "value" attribute of the region component with id "r1") evaluated to null.
This is typically due to an error in the configuration of the objects referenced by this expression.
If it helps, the expression "#{bindings.pagecreatepage1}" evaluates to "null".
If it helps, the expression "#{bindings}" evaluates to "sampleApp_view_homePageDef". Now using an empty RegionModel instead.
