Key: TOMAHAWK-799
URL: http://issues.apache.org/jira/browse/TOMAHAWK-799
Project: MyFaces Tomahawk
Issue Type: Improvement
Components: Data Scroller
Affects Versions: 1.1.5-SNAPSHOT
Environment: Windows XP, jakarta-tomcat-5.0.28.
Reporter: Jorge Andrés Vásquez
Priority: Minor
The the HtmlDataScroller class is currently using the actionListener event (in
particular the ScrollerActionEvent) to maintain the firstRow index of the
dataTable. My idea is that if someone needs to control this variable from
inside a managed bean for example in order to maintain the page number in a
master/detail scenario then that person can use this actionEvent too. But in
order for broadcast method of HtmlDataScroller component class to not overwrite
the control logic that one can implement from the bean the suggestion is to
modify method: "public void broadcast(FacesEvent event)" changing the
broadcastToActionListener(scrollerEvent); to the end of the if (event
instanceof ScrollerActionEvent)...portion of the code. This change allows
anyone to control the rowIndex from a bean with a simple event-based logic.
