Cascading af:popup windows

This time I'm back with a very simple tip on af:popup. The use case requirement was to display popup on another popup and the developers do not want to add an af:dialog or af:panelWindow to the parent popup as it does not gives the look and feel that they are looking for.

So the solution is to define the child popup inside the parent as nested. This makes sure that parent is displayed when child is made visible. What if one keep child outside of parent? Well,  if the child is kept outside of parent (note that parent popup, here, does not have af:dialog or af:panelWindow for holding its  contents) in JSF page, parent was getting closed while child is displayed. So the code snippet that worked for them look like as given below:

<!-- Parent popup--> <af:popup id="p1" autoCancel="disabled" contentDelivery="lazyUncached"> <af:outputText id="ot1" value="test value"> <af:showPopupBehavior popu…

Why findNodeByKeyPath() fails while reading selected rows in an af:table

This topic may looks simple for many of you. However some simple mistakes may spoil your entire day. Let me share a point that I learned recently while working with a customer. The requirements was to read all the selected rows from the multi-select table's selectionListener method defined in a managed bean. The code that is initially used for iterating over selected rows was as follows.

Wrong Implementation


public void wrongAPIForFindingSelectedRows(SelectionEvent selectionEvent) { RichTable _table = (RichTable)selectionEvent.getSource(); RowKeySet rks = _table.getSelectedRowKeys(); Iterator rksIterator = rks.iterator(); //Store original rowKey Object originalRowKey = _table.getRowKey(); try { while (rksIterator.hasNext()) { Object rowKey = rksIterator.next(); _table.setRowKey(rowKey); //stamp row //get current node object JUCtrlHierNodeBinding selectedNode = …

Prart 2 - Hiding Unwanted Operators in Advanced mode of af:query Component

This is in continuation of one of my old post Part1 - Hiding Unwanted Operators in Advanced mode of af:query Component. There I discussed how to remove built-in operators (displayed in Advanced mode of af:query component) for a view criteria item attribute by specifying <CompOper/> in the view object XML file against appropriate view criteria item.

Recently I learned that, you can even  specify <CompOper/> against appropriate attributes in a view object as well. This makes your life much easier, because here you do not need to to repeat the same <CompOper/> definition across view criteria items appearing in multiple places. This also takes care of those attributes which are not included in view criteria during design time, still appearing at runtime in the search when some one adds them using Add Fields option in the Advanced mode of the query component.

Note that JDeveloper does not provide any visual aid to restrict the operators for an attribute at design time. …
