p:panel / p:accordionPanel dont keep state

[rene.guenther]

Hello ,

we just started with primefaces. We'd like to keep the collapsed/expanded state between requests of p:panel or p:accordionPanel.
Since I also don't know the YUI framework, I have no idea how to do those things. Is it in principle possible to keep that state?

Thanks
Rene

Yes. It is possible to maintain the state of the selected tab of the accordionPanel through the activeIndex attribute. To enable multiple selection, use comma as separator.

Code: Select all

  <p:accordionPanel multipleSelection="true" fade="true" activeIndex="#{yourbackingbean.activeIndex}">

where you can assign a String value of 1,2 to #{yourbackingbean.activeIndex}

Thank you. I saw that attribute but I thought it would only work with single selection

Rene, accordionPanel keeps it's state between requests, there's a hidden variable keeping track of active tab indexes. activeIndex attribute is used more likely to define which tabs are expanded by default.

But panel, I guess you meant panel with toggle="true", it doesn't keeps it state but we can add it as an enhancement for the upcoming release. I've created a new issue for this;

Yes, I meant the panel with toogle=true.
I tried accordionPanel now and it keeps the state and it is actually useful in that regard but it looks like that I cant nest a tabView in an accordionPanel. With the panel I didnt had that issue.

cheers

Can you post your tabview in accordion panel code Rene so that I can try to run it locally.

[rene.guenther]

I cant reproduce it anymore. Probably I had some tags at the wrong place while rearranging the form. Now its working pretty good with the accordionpanel

Done I've changed panel to be stateful as well along with some refactoring and other improvements. Now panel keeps it's toggle state along subsequent requests. In addition a new optional feature called collapsed is added to control the initial state of panel. So if you set collapsed="#{boolean el}, rendering of body will be conditional.

You can grab these via a 1.0.0.RC SNAPSHOT;

Thanks! We going to try the RC soon. The accordion works pretty well for requirements too though.

I'm having a problem with the p:panel toggle state, using PrimeFaces 1.1.
I have a panel like:

Code: Select all

<h:form id="panelForm">
	<p:panel header="Panel" toggleable="true">
		<h:outputText value="Panel content" />
	</p:panel>
	<h:commandButton value="Submit" />
</h:form>

If I collapse the panel and submit, it is not collapsed when the page renders again.
