Implementation --
<h:panelGroup id="pnlGrp_editCustomerGroupManageLocal">
<asset:inputAutoComplete datatype="static" labelValue="abcd" id="samleAuto" varname="availableTags" >
<f:ajax event="clientEvent" onevent="alert('sfdksd')"></f:ajax>
</asset:inputAutoComplete>
</h:panelGroup>
The above is the implementation of composite component . I am not able to trigger ajax event from inside the component.
Please help me to know what could be the possible issue with the code .
