------------------------------------------
Duplicated: https://issues.jboss.org/browse/RF-12033
Bug is in JavaScript part.
When EDT is placed on hidden page (tab) parent DIV has attribute display=none, and in this
case invocation: this.element.clientWidth returns 0.
Source-code: RichFaces-4.2.2.Final
extendedDataTable.js#updateLayout
Line 283: var width = Math.max(0, this.element.clientWidth - offsetWidth);
width == 0 and we have this
Line 307: this.normalPartStyle.display = "none";
Hidden parent is a root cause.
As a workaround i can suggest the next changes
extendedDataTable.js#initialize:
Lines 396: this.updateLayout();
Lines 396: this.updateScrollPosition(); //TODO Restore horizontal scroll position
replace with:
if (this.element.parentNode.clientWidth > 0) {
this.updateLayout();
this.updateScrollPosition(); //TODO Restore horizontal scroll position
}
More elegant solution would be some hook - when parent div is become visible -
updateLayout is invoked, but I don't see the way in which we can do it now.

Key: RF-11551
URL: https://issues.jboss.org/browse/RF-11551
Project: RichFaces
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: component-panels-layout-themes, component-tables
Affects Versions: 4.1.0.Milestone2
Environment: Tomcat6, Firefox 7, IE 8, myfaces 2.1.3
Reporter: Rene O
Labels: waiting_on_user
Fix For: 4.3-Tracking
Attachments: jsftest.war
A testcase to reproduce this issue is attached.
Steps to reproduce this issue:
1. http://localhost:8080/jsftest/tabandtable.jsf
2. switch to tab "Tab with Table" -> table has scrollbar
3. switch to tab "Tab with Table2" -> table has no scrollbar, which is not
the expected behaviour
4. switch again to tab "Tab with Table" -> table has now also no scrollbar,
which is not the expected behaviour
If you use switchType=server everything works as expected.
If you use switchType=client there is another problem:
The content of the tables is not visible. It is visible after you use the dataScroller.
But there is also no scrollbar visible.
