Well sure this works... just like

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

I must be missing something...
what's the point?

@Sergej

I understand this issue, but if I use an expression to write into - a session scoped value - it does not maintain the expanded value

[opr]

and btw

expanded = "true"

works. Only if I use EL expression something goes wrong.

This was exactly the point; To check how the standard component with read/write attribute works with EL.

Result.
The deferral EL like "#{2==2}" are failed.
The immediate EL like "${2==2}" works

So, reopen the issue with note that it should work with immediate EL. Refer to this forum post.

Sergey,

I'm not quite sure i understand, since both fails for me with the expanded attribute of the panelMenuGroup, and both works for me with <h:inputText>,
anyway, i'll reopen the issue as you said...

[bpons]

BTW,

I wonder if all would not be simpler if you just assume that when selectedChild attribute of the panelMenu is set, then the developper certainly wish that the corresponding panelMenuGroup (and his possible parents) is/are expanded....

[opr]

Finally I created the following workarround:

1) Store the expand/collapse information for every PanelMenuGroup in a session scoped bean

2) Patch org.richfaces.component.UIPanelMenuGroup.java by reimplementing the setter and getter for the "expanded"-Attribute in the following way:

public boolean isExpanded(){
 SessionBean sb = (SessionBean)FacesContext.getCurrentInstance().getExternalContext().getSessionMap().get("sessionBean");
 return sb.getExpansionMap().get(this.getId()).booleanValue();
 }

public void setExpanded(boolean expanded){
 SessionBean sb = (SessionBean)FacesContext.getCurrentInstance().getExternalContext().getSessionMap().get("sessionBean");
 setValue(sb.getExpansionMap().get(this.getId()).booleanValue());
 }

My Session Bean contains

private HashMap<String, Boolean> expansionMap = new HashMap<String, Boolean>();

 public SessionBean()
 {
 expansionMap.put("pg1", new Boolean(false));
 expansionMap.put("pg2", new Boolean(false));
 expansionMap.put("pg3", new Boolean(false));
 expansionMap.put("pg4", new Boolean(false));
 expansionMap.put("pg5", new Boolean(false));
 expansionMap.put("pg6", new Boolean(false));
 expansionMap.put("pg7", new Boolean(false));
 expansionMap.put("pg8", new Boolean(false));
 expansionMap.put("pg9", new Boolean(false));
 expansionMap.put("pg10", new Boolean(false));
 expansionMap.put("pg11", new Boolean(false));

 }

In the action method the boolean values are toggled in the following way:

 public void menuAction(ActionEvent ae)
 {
 if (ae.getComponent().getId().equals("pg1"))
 expansionMap.put("pg1", new Boolean(!expansionMap.get("pg1").booleanValue()));
 if (ae.getComponent().getId().equals("pg2"))
 expansionMap.put("pg2", new Boolean(!expansionMap.get("pg2").booleanValue()));
 if (ae.getComponent().getId().equals("pg3"))
 expansionMap.put("pg3", new Boolean(!expansionMap.get("pg3").booleanValue()));
 if (ae.getComponent().getId().equals("pg4"))
 expansionMap.put("pg4", new Boolean(!expansionMap.get("pg4").booleanValue()));
 if (ae.getComponent().getId().equals("pg5"))
 expansionMap.put("pg5", new Boolean(!expansionMap.get("pg5").booleanValue()));
 if (ae.getComponent().getId().equals("pg6"))
 expansionMap.put("pg6", new Boolean(!expansionMap.get("pg6").booleanValue()));
 if (ae.getComponent().getId().equals("pg7"))
 expansionMap.put("pg7", new Boolean(!expansionMap.get("pg7").booleanValue()));
 if (ae.getComponent().getId().equals("pg8"))
 expansionMap.put("pg8", new Boolean(!expansionMap.get("pg8").booleanValue()));
 if (ae.getComponent().getId().equals("pg9"))
 expansionMap.put("pg9", new Boolean(!expansionMap.get("pg9").booleanValue()));
 if (ae.getComponent().getId().equals("pg10"))
 expansionMap.put("pg10", new Boolean(!expansionMap.get("pg10").booleanValue()));
 if (ae.getComponent().getId().equals("pg11"))
 expansionMap.put("pg11", new Boolean(!expansionMap.get("pg11").booleanValue()));
 }

Dirty, but works....

Hello,

I've created RFC: http://jira.jboss.com/jira/browse/RF-2957 for autoexpansion attribute.

BTW, I've tried

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

and got:

03.04.2008 17:04:38 javax.faces.component.UIInput updateModel
SEVERE: /pages/test1.xhtml @14,36 value="${2 == 2}": Illegal Syntax for Set Operation
03.04.2008 17:04:38 com.sun.faces.lifecycle.RenderResponsePhase execute

so that still doesn't work well. Submit form to see the messages

Thx about the feature request, that's pretty cool.

Hi!

Can anyone confirm that this issue is now working properly? I ran into it using version 3.3.3.FINAL, but the issue on jira has been closed.

Oh sorry that's not what I meant. I'm still having problems with EL expressions in the expanded property of the menugroup. The error message is the same as the one in the OP.
