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?
Is there a way to make every tab component object STATIC across different jsp
pages? Am I missing something from the code below?
This is code from my JSP page that implements trinidad tab navigation
components:
<tr:navigationPane hint="tabs">
<tr:commandNavigationItem id="login" text="Home"
actionListener="#{commandNavigationItem.navigationItemAction}"
action="#{navigationCaseBean.getCaseValue}" selected="true"/>
<tr:commandNavigationItem id="codeOfCond" text="Code of Conduct"
actionListener="#{commandNavigationItem.navigationItemAction}"
action="#{navigationCaseBean.getCaseValue}"/>
<tr:commandNavigationItem id="personalInfo" text="Personal Info"
actionListener="#{commandNavigationItem.navigationItemAction}"
action="#{navigationCaseBean.getCaseValue}"/>
<tr:commandNavigationItem id="moreInfo" text="More Info"
actionListener="#{commandNavigationItem.navigationItemAction}"
action="#{navigationCaseBean.getCaseValue}"/>
</tr:navigationPane>
