After spending sometime debugging this, Found that

Tobago.addAjaxComponent(':page:panel); has to be called incase if the panel has to be updated using AJAX.

Is this a bug in 1.0.9??

Hi Volker,

Thanks for the Quick Response.

When i was trying this, getting the following javascript error.

LOG.debugAjaxComponents is not a function.       tobago.js (line 595)

I'm running on Tobago 1.0.9. I have gone through the js code and found that there is no function called "debugAjaxComponents" defined in the class LOG.

Am i missing anything ??

Hi Varma,

i have no experience with 'thirdparty AJAX frameworks', but i don't
think they work with tobago.

But you can do this with the tobago internal ajax partial reload feature.

put the second tc:selectOneChoice into a tc:panel with defined
clientId ( this means you set a id to this panel and to all
surrounding namingContainer components).

add a 'change' facet to the first tc:selectOneChoice with a action to
change the options for the second one, and a renderedPartially
attribute to update.

--- jsf ------------------------
<tc:page id="page">
...
<tc:selectOneChoice ...>
  <f:selectItems .../>
  <f:facet name="change">
    <tc:command action="#{ bean.selectOptions}">
      <tc:attribute name="renderedPartially" value=":page:panel"/>
    </tc:command>
  </f:facet>
</tc:selectOneChoice>

<tc:panel id="panel">
  <tc:selectOneChoice ...>
    <f:selectItems value="#{bean.items2}"/>
  </tc:selectOneChoice>
</tc:panel>
...
</tc:page>
--- /jsf ------------------------

the action method "public String selectOptions() {...}" should update the
selectItems in items2 property.
And MUST return null, because you don't want to navigate to anohter view.
