[richfaces-issues] [JBoss JIRA] (RF-8084) Panelbar does not expand with more than 4 panelBarItems

[Virage Group (JIRA)]

    [ https://issues.jboss.org/browse/RF-8084?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12697967#comment-12697967 ] 

Virage Group commented on RF-8084:
----------------------------------

I can reproduce the bug as described above with FF 12 (not IE9). With 4 panelbar items the computed height (h) is 2px  but with 3 panelbar items the height is correct (100%). If I unzoom (ctrl -) the bug disappears.

Notices that, unlike your livedeomo, my panelbar does not have a fixed height defined. 
I can reproduce the bug with height=100% or with no height defined on the panelbar. If I set a fixed height (eg height='400'), the panelbar item has the correct height.

> Adding a rich:panelBar with more than 4 panelBarItems causes the panelBarItems to stay hidden.
> Under Mac and FF 3.5 the pannels do not open anymore. If your zoom (Cmd +), the panels open again.
> Under Windows and IE 8 you need to zoom one level (Ctrl +).
> In the panelbar.js (showSlide function) this piece of code contains the problem.
> slide.content.style.height=(h>0?h:0)+"px";
> if (h<=1 && (this.panel.style.height=="" || this.panel.style.height.indexOf("%")!=-1)) {
> 	this.panel.style.height="";
> 	slide.content.style.height="100%";
> }
> h is the contentHeight. 'Normally' this returns a value which is <=1. But for some zoom levels and more than 4 panelBarItems this value gets bigger. This causes the height being set to 2 or 3 and the panelBarItem looks clossed.
> This is probally caused by some rouding problem. A difference between offsetHeight and clientHeight?
> Locally I fixed the problem to disable the check and always set the height of the slide.content to 100%.
