Region Interaction Example 4 - Using Parent Action Component

Assume the following UI:

Here, the top region before the separator represents the parent task flow, and the region below the separator represents the child task flow. In the child task flow, on clicking the ‘Move Parent’ button, the parent task flow navigation is performed, as shown below:

However, on clicking the ‘Move Child’ button, the navigation in the child task flow is performed, as shown in below image:

To perform this type of navigation, Parent Action component is used. Parent action component is used in the child task flow to perform the navigation in the parent task flow. The following image shows the parent task flow used in the above specified flow:

The ParentView.jsff refers to the child task flow and the following image shows the content of the child task flow:

The files used in this flow are:

Here is the code of the above specified file used in the flow:
