Shared Node Model not created

Question

I have created multiple task flows and created the adf menu models. I have created the views for all the nodes and have created shared nodes for the lower level task flows. I have verified that the managed beans are all present for each task flow and they are located in the appropriate menu models XML file and referenced in the root_menu.
When I run the page I get the following error: java.lang.NullPointerException: Shared Node Model not created for query_menu. Check for the existence of the corresponding managed bean in your config files.
I did find another post related to this problem, but did not understand the post.
They suggested looking at the following:
"The file that should contain the menu bean is the file specified in the service-level property "Service Adfc Config". Can you check whether this property has a valid value? Also, make sure the advanced service-level checkbox property "generate ADFc Config Files?" is checked."
Where do I locate the service-level property "Service Adfc Config"? I have been looking through all the config files in the application and the preferences in JDeveloper.
I am new to JDeveloper and ADF.
Thank you for your help.

Hi,
It makes perfect sense that menu_root.xml has a reference to the managed bean #{JhsMigrateModuleMenu}.
This bean should be defined in the adfc-config for your appmodule, probably /WEB-INF/adfc-config-jhsmigratemodule.xml
It looks like this (with different names):
<!-- DEBUG:BEGIN:MENU_BEAN : default/misc/facesConfig/menuBean.vm, nesting level: 2 -->
<managed-bean>
<managed-bean-name>AppModuleMenu</managed-bean-name>
<managed-bean-class>oracle.jheadstart.controller.jsf.bean.JhsXMLMenuModel</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
<managed-property>
<property-name>source</property-name>
<property-class>java.lang.String</property-class>
<value>/WEB-INF/menu-appmodule.xml</value>
</managed-property>
</managed-bean>
<!-- DEBUG:END:MENU_BEAN : default/misc/facesConfig/menuBean.vm, nesting level: 2-->
I guess that this definition is missing or has the wrong name or something. Perhaps it is pointing to an invalid XML menu model file (in my case /WEB-INF/menu-appmodule.xml)
Can you post your findings here?
