Hi Malu,
You need change the code of iframe like below code getting Incident list based on Caller
<g:ui_reference name="requester_id" query="active=true" table="sys_user" id="requester_id" value="${gs.getUserID()}" displayvalue="${gs.getUser().getName()}"/>
<button class="button" style="margin-left:5px" id="getList" onclick="getIncList();">Get User Incidents</button>
<div id="targetList">
<iframe src="incident_list.do?sysparm_query=caller_id=javascript:gs.getUserID()" style="min-height:400px;width:100%;" scrolling="no" frameborder="0"></iframe>
</div>
<script>
function getIncList(){
var caller = document.getElementById('requester_id').value ;
var newIframe = '<iframe src="incident_list.do?sysparm_query=caller_id='+caller+'" style="min-height:400px;width:100%;" scrolling="no" frameborder="0"></iframe>' ;
document.getElementById('targetList').innerHTML =newIframe ;
}
</script>
