how to call bean method from method call activity in taskflow.

NessNov 10 2017 — edited Nov 24 2017

Hi all,

m using jdev verson 12.2.1.2.0

i have created a bean method which i want to call from taskflow:

I have registaered in managed bean section of taskflow:

the bean is:

**public void getDocuIndBean() {**

    **Map param = AdfFacesContext.getCurrentInstance().getPageFlowScope();**

    **param.put("documentIndValue", "D");**

}

But m getting exception while calling this method:

<oracle.adf.controller> <ManagedBeanFactory> <warnIfNotSerializable> <ADFc: Managed bean SupplierRequisition, implemented by ctravel.view.backingBeans.SupplierRequisition, defined in /TaskFlows/Requisition-Dom-task-flow.xml in file:/C:/Users/Administrator/AppData/Roaming/JDeveloper/system12.2.1.2.42.161008.1648/o.j2ee/drs/CorporateTravel/CTravelViewControllerWebApp.war/TaskFlows/Requisition-Dom-task-flow.xml, does not implement Serializable and will be placed in pageFlow scope, which might be serialized.>

<oracle.adf.controller> <MethodCallActivityLogic> <execute> <ADFc: #{pageFlowScope.SupplierRequisition.getDocuIndBean}: Exception while evaluating method-call activity EL expression #{pageFlowScope.SupplierRequisition.getDocuIndBean}.>

<oracle.adf.controller> <LogUtils> <reportIncident> <>
