seam 2.0 - problem upgrading to richfaces 3.2.0 GA from 3.1.

[powerhouse_b]

Hi.

I have a Seam project set up using RedHat Developer, and it uses RichFaces 3.1.2. I changed it to use 3.2.0. (problems here: )
After upgrading, I have a problem with a code that used to work on the previous version.

<rich:panelMenuGroup label="Salariati" action="#{leftMenuState.expandMenu(messages.MenuGroup_Employees)}"
 expanded="#{leftMenuState.currentMenuExpanded(messages.MenuGroup_Employees)}" expandMode="ajax">

This code should was used to keep the expanded menu after a page reload. With the new version, i get the fallowin error:

FacesMessage(s) have been enqueued, but may not have been displayed.
sourceId=j_id39[severity=(ERROR 2), summary=(/layout/leftMenu.xhtml @91,104 expanded="#{leftMenuState.currentMenuExpanded(messages.MenuGroup_Employees)}": Illegal Syntax for Set Operation), detail=(/layout/leftMenu.xhtml @91,104 expanded="#{leftMenuState.currentMenuExpanded(messages.MenuGroup_Employees)}": Illegal Syntax for Set Operation)]

Also, a

<rich:panelMenuItem action="/pages/data/ContracteList.xhtml" label="Contracte" mode="ajax" >

is not working any more (is does the ajax call, but the reload is not happening).

Thanks!

My first question is - are you using JSP of Facelets?

[powerhouse_b]

I am using Faceletes on Jboss 4.2.1.

I am using JSPs and facing the same problem after upgrading from 3.1.4 to 3.2.0.

Any ideas are welcome

In my case, I have modified the pages, removing the expanded attribute and using a binding to provide the same functionality.

I have the same problem on a facelets application (JBoss 4.0.5, SEAM 1.2)

I created an issue in RichFaces JIRA, but it was promptly rejected :

http://jira.jboss.com/jira/browse/RF-2922?page=all

Maybe we should reopen this one...

@powerhouse :

Can you clarify this workaround?
I would be kinda interested :o)

[powerhouse_b]

In my case, i had to preserver the expanded panelMenuGroup of a panelMenu after reloading the page. I had a session scope bean that held the expanded menu and a method that returned a boolean if the panel menu was expanded, passing the name of the panelMenuGroup:

expanded="#{leftMenuState.currentMenuExpanded(messages.MenuGroup_Employees)}

Because the expanded did not work any more, did something like this for every panelMenuGroup:

<rich:panelMenuGroup id="employeeMenu" label="Salariati" action="#{leftMenuState.expandMenu(messages.MenuGroup_Employees)}"
 binding="#{leftMenuState.employees}">

On the the leftMenuState bean, I have a

private HtmlPanelMenuGroup employees = new HtmlPanelMenuGroup();

//...
public void expandMenu(String menu) {
 employees.setExpanded(false);
/./..
 if (menu.equals("MenuGroup_Employees"))
 employees.setExpanded(true);
//..
}

So all attributes of the panelMenuGroup can be accesed and modified from the code.

That's all. If you have any questions, I will be more the happy to help.

Expanded property should be read-write.
For some reason, in 3.1.4 it was read-only.

Ok thx for your answer.

I'm not sure it applies to my case though, since i expanded the menu depending on a param passed by the content part of the ui composition.

Guess i'll have to find another way :o(

Try <h:inputText value="#{2==2}" />
If it works, reopen.

@maksim :

And what would be now a simple way to dynamically assign true or false to expanded attribute without having to rely on a binding like powerhouse did?

I mean it was quite simple before

in a page named test.xhtml for example :
<ui:include src="nav.xhtml">
<ui:param name="selectedItem value="test"/>
</ui:include>

and in the corresponding panelMenuGroup in the nav.xhtml i just had to set expanded="${selectedItem == 'test'}

@powerhouse

I tried your workarround, but it does not work :-(

I am using JSF 1.2, Rich Faces 3.2.0 in Tomcat 6

With version 3.1.4 we were using the workarround storing the "expanded"-Attributes in a session scoped bean. Worked perfectly.

Now with 3.2.0 even when binding the whole panelMenu after submitting the page my menu is collapsed and if I do not find a solution soon, I will collapse too....

Any Ideas?

@Sergey :

What do you mean?

expanded="<h:inputText value='#{2==2}' />"> ?

Parse error without any doubt...

[sergeysmirnov]

<h:form>
 <h:inputText value="#{2==2}" />
</h:form>
