i have developed 2 custom task flows TaskFlowA , TaskFlowB
and deployed them as shared library and added them to resource catalog
the the taskFlowB has input Paramter , called url which is the value for inlineFrame component
and taskFlowA has 3 af:links with actionListner  link1 , link2 , link3
those 2 task flows are added on webcenter portal page as a components

    For communicating Task Flows within a Oracle WebCener Portal Page you can make use of the Contextual Events framework provided by Oracle ADF.

    • Your Task Flow A can throw a Contextual Event that you can define declaratively or fire it programmatically with a Payload included.
    • Your Task Flow B consumes the Contextual Event of Task Flow A by registering himself as a consumer in the same WebCenter Portal Page (in the Page Definition).

    Kind regards.
