Making a MDI Application by using the MultiTaskFlow

Multiple Document Interface (MDI) is an application style you can use to open multiple windows (called sheets/tabs) in a single window and move among the sheets. It is a most common thing and used desktop applications. Now we can achieve same by using multi task-flow concept of ADF and customize as per our business requirement.

In ADF Application, we can achieve by using multi task-flow concept and making the Java class with Collections to handle the multiple sheet adding, removing, selection and closing. Please follow the below steps,

• Create a Java Class of MDI.java & Sheet.java and use the property by using the Collection with wrapper of TaskFlowBindingAttributes and Sheet classes.

• Create a Page by using the ADF Page Template and include a af:panelTabbed with af:showDetailItem dynamically by using the af:forEach looping.

• Create a PageDef for Template and include a ‘multiTaskFlow’ tag under the <executables>

• Include a <definitionFactories> for TaskFlowBindingDefFactoryImpl under the DataBindings.cpx file.
