Portlet with Ajax4jsf

[maiky]

Hello,

I want to know if I can use Ajax4jsf when develop a portlet ?
It seems to me that I read it didn't work.

I use JBoss portal 2.6.1 (GA) and JBoss AS 4.0.5.

Have got any solutions to include Ajax in portlet when using JSF ?

Thks.

PS: Sorry for my bad English

I am also interested if this does or does not work in a portlet...

I have been trying to get this to work with no success....


Ajax4JSF?
RichFaces?

Thanks

The releases are not there yet, wait a bit. It's still experimental anyway.

Of course if you are curious and not beginner you can make your path trough the compilation and configuration otherwise it's wiser not to go on cutting-edge technologies.

I will just wait a bit....

Thanks Thomas...

[indyjones]

if anyone is curious, I do have Tomahawk working inside the portlet...

Its a nice alternative...

Thanks

For the impatient check this branch of a Drag n Drop prototype using Ajax4JSF in a portal environment

Hint: Look at the SVN History for ideas of what files to look at


Thanks

Thks for response.

If I've got time, I try to work on it.


PS: Sorry for my English.

I will also be playing with this...

Thanks so much!!

indyJones: do you know if all tomahawk components can be used inside a portlet? I'm curious starting to use RichFaces, but according to another thread, the JBoss Portal 2.6 isn't ready for RichFaces yet.

A wiki page has started to list the supported components if you try some and sucessfully have them working in a portlet environment please update the page:

Thomas, as you can see from my other thread on the same subject, there are still things not working correctly:

I get a Stacktrace when trying to use RichFaces in a JSF Portlet. Any input?

Hi guys,

I am trying to deploy RichFaces portlet on Jboss Portal for about 2 days
I've read everything I could find on the Internet with no success. I hope You will be able to help me.

I am using
JBoss Portal 2.6.2.GA with bundled JBoss AS
RichFaces 3.1.2.GA
portlet-3.1.2.GA

web.xml

....
<context-param>
<param-name>org.ajax4jsf.VIEW_HANDLERS</param-name>
<param-value>org.ajax4jsf.portlet.application.PortletViewHandler</param-value>
</context-param>
....

portlet.xml

....
<portlet-name>Portlet</portlet-name>
 <portlet-class>org.ajax4jsf.portlet.AjaxFacesPortlet</portlet-class>
 <init-param>

Portlet successfully deploys, but when viewed the Portal throws an exception:

Thanks in advance!

dimiter_a, have you tried to change the managed-bean-scope of the ajaxContext to something else than request? I'm not sure if that's you problem, or if you can live with another scope, but it's worth a chance. I've read some other places that people have experienced problems with request scope in portlets.

[dimiter_a]

Finally I've made it work! :)

in the faces-config.xml should be added the folowing segment:

<factory>
<faces-context-factory>org.ajax4jsf.portlet.context.FacesContextFactoryImpl</faces-context-factory>
</factory>

It worked for me. I hope this will help someone else.
