>                 URL: https://jira.jboss.org/jira/browse/RF-7205
>             Project: RichFaces
>          Issue Type: Bug
>    Affects Versions: 3.3.1
>         Environment: JRE 6, Tomcat 6
>            Reporter: Matthew Lieder

> The following works fine when rendering:
> <rich:simpleTogglePanel label="Panel" switchType="client" opened="#{true}">
> but if I close the panel and then submit the page the following error message is shown:
> /test.xhtml @50,205 opened="#{true}": Illegal Syntax for Set Operation
> However, if I set it to a bean property (like opened="#{myBean.property}") then it works fine. I believe the problem is that it's trying to update the EL expression with the current state of the opened attribute.
