Webcenter folder not working 11.1.1.6 NullPointerException

Our WebCenter portal has a custom menu and when clicking on a folder link I got an empty popup then next click a NullPointerException.

Fix just added a check and disable the links we where using if they are not navigable.

<af:commandLink id="mnuCbx"
      actionListener="#{navigationBean.processAction}"
      blocking="true" action="pprnav"
      disabled="#{!node.navigable}">
    <af:outputText value="#{node.title}" id="pt_ot2"/>
    <f:attribute name="node" value="#{node}"/>
    <f:attribute name="treeLink" value="#{true}"/>
</af:commandLink>

Very cool document - set of expressions for web center and an explanation

MANIFEST.MF merge JDeveloper for an executable jar

Goto your project > properties. Then click on deployment in the menu. Edit or add a jar deployment profile.

REALLY this caught me. My merge file contents: Class-Path: commons-codec-1.3.jar [...empty line here CRLF...]

JBO-25013: TooManyObjectsException

oracle.jbo.TooManyObjectsException: JBO-25013: Too many objects match the primary key oracle.jbo.Key[Key null ]. Ok so for you it may be trying to insert a duplicate record this should explain your problem (also check trigger they could be the cause.) NOTE: You can also try to create a new duplicate EO if you have a page with two VO's using the same EO. This could sort your problems. For me I needed to add a launch listener on my LOV and clear the cache of my vo. LOV <af:inputListOfValues id="NameId" popupTitle="#{bindings.Name.hints.label}" value="#{bindings.RolName1.inputValue}" label="#{bindings.RolName1.hints.label}" model="#{bindings.RolName1.listOfValuesModel}" required="#{bindings.RolName1.hints.mandatory}" columns="#{bindings.RolName1.hints.displayWidth}" shortDesc="#{bindings.RolName1.hints.tooltip}" launchPopupListener="#{backingBeanScope.backingBean.launchPop...
