How-to: Reinitialize bounded, page fragment based taks flow programmatically

Sometimes you need reinitialize region based ADF task flow - especially when you want to use task flow in popup. There exists declarative solution in which you set properties:

• RefreshCondition, or
• set Refresh to ifNeeded

Unfortuantely declarative solution wouldn't work in some cases, while code-based works for me perfectly. What's more software solution is very simple.

To restart page-fragment, bounded taskflow from code you should access the task flow model from backing bean:

RegionModel model = (RegionModel)JSFUtil.getValueEl("#{bindings.my-task-flow.regionModel}");

and next refresh this model:

model.refresh(FacesContext.getCurrentInstance());
