Problem with reRender

[chickenwings]

Hi,

i have a problem with a reRender attribute in my <a4j:support > tag:

<a4j:support event="onchange" ajaxSingle="true" reRender="shortname"/>

If i remove the ajaxSingle tag, the component with id="shortname" will be rendered, but with this attribute not.

Cann anybody give a hint?

thx

Hi,
it is attached to a select component (use JSF):

<h:selectOneMenu id="activity_type_follow" styleClass="input_text" value="#{activityManagerBean.activityType}" validator="#{activityManagerBean.validateType}" >
 <a4j:support event="onchange" ajaxSingle="false" reRender="shortname" />
 <f:selectItem itemValue="0" itemLabel="- Choose Activity Type -" />
 <f:selectItems value="#{activityManagerBean.activitytypeSelectItems}" />
</h:selectOneMenu>
<h:outputText value="* Shortname: " />
<h:inputText class="input_text" id="shortname" value="#{activityManagerBean.followShortname}" required="true" requiredMessage="Please give a Shortname to this Activity" />
