I use both actionListener (to set focus on selected tab, and set navigation case outcome corresponding to this tab by detecting its id value) and action (to return outcome string stored in the bean by actionListener) and navigation is okay now. I get moved to correct pages by clicking on its tabs, HOWEVER now the tabs are not being selected correctly. I move to a right page but the wrong tab is being selected. And it seems to be delayed by one click. Namely the focus of selected tabs get on the one that I previously clicked on. Now I found out after some testing that this happens because I am loading different jsp files every time I click on the tab. If I reload the same jsp page (I set all tabs to point to the one same jsp page) tabs are being selected correctly. This makes me think there is an issue with page scope and tab component. Seems to me that every time I load different jsp page (they are all including common code section for tabs), a new instance of tab component object is being created and it has no way of tracking its state from the previous page. Shouldn't these tab component objects be STATIC so that they retain their values across multiple pages. I mean shoudn't all different pages be refferencing one same object instance created when the first page containing tab components was loaded. And shouldn't all subsequent (different) jsp pages be still refferencing that same object?
Am I missing something here? Is there a way to make every tab component object STATIC across different jsp pages? -----Original Message----- From: Matt Cooper [mailto:[EMAIL PROTECTED] Sent: Mon 10/23/2006 4:05 PM To: [email protected] Subject: Re: ActionListener for navigation tabs Hi, Instead of using "actionListener", you may can use "action" like this: <tr:commandNavigationItem text="More Info" action="guide.moreInfo"/> or <tr:commandNavigationItem text="More Info" action="#{ demoCommandNavigationItem.moreInfo}"/> where #{demoCommandNavigationItem.moreInfo} is: public String moreInfo() { return "guide.moreInfo"; } Now, if you want to use actionListener for example to set more properties on the bean, you can implement both an actionListener and an action. If you wanted a single bean for all of your 4 tabs, the actionListener can have code to detect which tab was clicked, save off that info, then in the action, you can return a particular action string for the particular tab that was clicked.
