a4j:include problem

[alexanderbelov]

I have a problem with <a4j:include> component.
I am working with Ajax4JSF 1.1 + Facelets 1.1.12 + JSF RI 1.2_04 + RichFaces3.0 now. And I want to use EL-expression as value of "src" attribute.

For example:

<a4j:include src="#{bean.pageName}"/>

I have an exception this way. Can I do so?
Now I have to use templates fo Facelets and it is not very usefull. I tried to do the same with <ui:include> (documentation of Facelets says, that I can use EL-expressions), but I have an error too.

How can I use EL to include the other page to the current?

[ilya_shaikovsky]

use proper attribute. For me works fine.

<a4j:include viewId="#{bean.property}"/>

[alexanderbelov]

I have used the same too. I have the same problem.

[ilya_shaikovsky]

post please the stacktrace.

Method returns "/pageName.xhtml"

[ilya_shaikovsky]

my case

<a4j:include viewId="#{bean.property}"></a4j:include>

public String getProperty() {
 return "/pages/greeting.xhtml";
}

works fine for ajax4jsf 1.1.0
may be configuration issue?.. :/ may be you define two viewhandlers (both in faces-config and web.xml)?

[alexanderbelov]

Of course, no. I have been using ajax4jsf for 5 months.
Everything works good, but this feature...

Well, thank you. I'll try to do something. Maybe it's connected with using templates on the same page...

[sergeysmirnov]

http://anonsvn.jboss.org/repos/ajax4jsf/trunk/framework/src/main/java/org/ajax4jsf/taglib/html/facelets/IncludeHandler.java:

throw new FacesException("UIInclude component "
 + component.getClientId(ctx.getFacesContext())
 + " could't include page with path " + path, e);

So, if we have:

javax.faces.FacesException: UIInclude component j_id28 could't include page with path
at org.ajax4jsf.taglib.html.facelets.IncludeHandler.applyNextHandler(IncludeHandler.java:87)

It might mean the path is empty. I.e, your #{bean.pageName} just returns null (or empty string), but not the page name as you expected.

[alexanderbelov]

My method is:

public String getPageName()
{
 return "/simple.xhtml";
}

To tell the truth, I don't now, how it can return null or empty string.

[sergeysmirnov]

For the testing purpose, put
<h:outputText value="#{bean.pageName}"/> before the <a4j:include>

[alexanderbelov]

It seems, <a4j:include> doesn't support "rendered" attribute.
I've created the empty page and everything works fine.
The documentation says:

"If "false", this component is rendered."

I have thought that there is a mistake. But it seems, that it's true. And there is my question: why this component doesn't support this useful attribute?

[ilya_shaikovsky]

Yes this small mistake will be fixed after documentation rebuild. Thanks.

Make sure you don't have a redirect in your navigation rules. Redirects will break a4j:include...
