[ http://issues.apache.org/jira/browse/TOMAHAWK-799?page=comments#action_12458295 ] David Paterson commented on TOMAHAWK-799: -----------------------------------------
I implemented the same thing when experiencing the same problem syncing the Datatable.first to the backingbean.first. Unfortunately I came accross this defect first and uploaded a patch: https://issues.apache.org/jira/browse/MYFACES-47 Similar problem with a different suggested solution, creating a new tag to nest within the Datascroller. This way seems a bit easier though. > Use of the actionListener event of datascroller to maintain the index of the > first row inside a managed bean. > ------------------------------------------------------------------------------------------------------------- > > 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. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
