Bug with toggleControl & togglePanel for tab creation.

[rschreiber]

Hi,

I'm trying to create a left tab menu by using the toggleControl & togglePanel components.

The toggleControl define the tabs and the togglePanel define the tab's content,
these two are connected by the toggleControl attribute: panelId which points to the togglePanel id.

from time to time, when i switch from one tab to another i get the following exception:

i couldn't find any systematic scenario...

Any suggestion?

thanks..

use for attribute on the control to point it to the panel

[rschreiber]

already did it..... any more idea?

<rich:toggleControl for="navigationPanel" value="Agents & Employees"
 switchToState="agentsEmployees" />
<rich:toggleControl for="navigationPanel" value="Security"
 switchToState="security" />
<rich:toggleControl for="navigationPanel" value="Attachments"
 switchToState="attachments" />

<rich:togglePanel id="navigationPanel" value="agentsEmployees"
 switchType="ajax" stateOrder="agentsEmployees,security,attachments">

 <f:facet name="agentsEmployees">
 // some content
 </f:facet>
 <f:facet name="security">
 // some content
 </f:facet>
 <f:facet name="attachments">
 // some content
 </f:facet>
</rich:togglePanel>

another problem i have with it is that i can't define the tab first and then their content (as i do in the example....) the exception says there is no "navigationPanel" property.

By debugging i found that when the tabs ("toggleControl ") are created, the "navigationPanel" doesn't exist. When the "for" attribute of the "toggleControl " points on the "navigationPanel", the exception occurs...

thanks for your help......

what the jsf version do you use?

[rschreiber]

jsf v 1.1

[sergeysmirnov]

Could you place toggle controls after the toggle panel (just for testing purpose) ?

[rschreiber]

i did..

it helped (no 'null pointer exception'), but now it placed upside-down....
(first the tab's content and then the tabs....)

thanks for trying to help..... any more suggestions?

[rschreiber]

somehow the first problem fixed... (no exception while switching tabs)
but, the second problem remained...

[sergeysmirnov]

This is well known problem of JSF 1.0 and JSF 1.1 where the component tree is created at the same time when components are rendered. So, 'for' pointed to the component id that does not exist yet in the tree (see the top example at http://www.onjava.com/pub/a/onjava/2004/06/09/jsf.html)

The workaround might be duplicating buttons inside each three facets. Using 'for' is not required in this case.
