Problem with a4j:include

[dblue]

Hi!
I have big problem with <a4j:include>
This what I need is set viewId dynamicly. I was trying to do this in many differet ways, but I have always the same error.

This is my bean code:

@Name("panelMenu")
@Scope(SESSION)
public class PanelMenu implements Serializable {
 private String page;
 public String getPage() {
 return page;
 }

 public void setPage(String page) {
 this.page = page;
 }
}

This is my page code:

...
<a4j:form>
 <a4j:include id="inpage" viewId="#{panelMenu.page}"/>
</a4j:form>
...

This is my exception:

javax.el.ELException: /start.xhtml @65,58 viewId="#{panelMenu.page}": Error reading 'page' on type pl.binfo.view.menu.PanelMenu_$$_javassist_0

I was trying to surround <a4j:include> with <a4j:form> or use <a4j:keepAlive beanName="panelMenu"/>, but without any results.
The same error I have when I'm trying to use binding parameter.
The same bean which I use with <a4j:include>, works fine at the same page in many different places.

This is my configuration:

RichFaces 3.2.2
Seam 2.0.2.SP1

Can anybody tell me where is my mistake ??

Is your "page" empty?

[dblue]

No its not.
I was trying take this from differend side too, but without any results.

There is topic about <a4j:include> and binding parameter, so I wrote:

BEAN:

@Name("panelMenu")
@Scope(SESSION)
public class PanelMenu implements Serializable {

 transient private UIInclude include;

 public UIInclude getInclude() {
 return include;
 }

 public void setInclude(UIInclude include) {
 this.include = include;
 }

}

PAGE:

<a4j:include id="inpage" viewId="/pages/start.xhtml" binding="#{panelMenu.include}"/>

My error is exactly the same.
Application screaming: Error reading "include" ...

[ilya_shaikovsky]

please show the page which you trying to include.
Such exception mean that there is an error with the path to included file or templating/including error within included file.

[dblue]

My pages are almost empty:

<div>
NOTHING
</div>

Hello dblue,

I tried to reproduce your problem on our local environment and all look fine.
Could you please get more details info about your project, including its folders structure; or just attach simple example of project.

I found, that I made many simple mistakes, so after cleaning every thing works good.
