GlideAjax returning null

[jiral]

I have a UI Action that calls a UI page  that do a GlideAjax to update the task activity due but it does not work

UI Page HTML

<?xml version="1.0" encoding="utf-8" ?>
<j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null">

	<j:set var="jvar_sysid" value="${RP.getWindowProperties().get('sysid')}"/> 
	<j:set var="jvar_tablename" value="${RP.getWindowProperties().get('table_name')}"/>  

	<style type="text/css">
		.tg  {border-collapse:collapse;border-spacing:0;margin:0px auto;}
		.tg td{border:none;font-size:14px;
		overflow:hidden;padding:10px 5px;word-break:normal;}
		.tg th{border:none;font-size:14px;
		font-weight:normal;overflow:hidden;padding:10px 5px;word-break:normal;}
		.tg .tg-uns3{text-align:center;vertical-align:middle}
		.tg .tg-q7tc{text-align:center;vertical-align:middle}
		@media screen and (max-width: 767px) {.tg {width: auto !important;}.tg col {width: auto !important;}.tg-wrap {overflow-x: auto;-webkit-overflow-scrolling: touch;margin: auto 0px;}}
	</style>

	<div class="tg-wrap"><table class="tg">
		<tbody>
			<tr>
				<td class="tg-q7tc" colspan="2"><g:ui_date name="datetime" id="datetime"/></td>
			</tr>
			<tr>
				<td class="tg-q7tc" colspan="2"><g:dialog_buttons_ok_cancel cancel="return onCancel();" ok="return onSubmit();"/></td>
				<input type="hidden" id="task_table" name="task_table" value="${jvar_tablename}"/>		
				<input type="hidden" id="task_sysid" name="task_sysid" value="${jvar_sysid}"/>
			</tr>
		</tbody>
		</table>
	</div>	

</j:jelly>

UI Page Client Script

function onCancel() {
	GlideDialogWindow.get().destroy();
	return false;
} 

function onSubmit() {
	var dateval = document.getElementById('datetime').value;
	var fxtime = '18:00:00';
	var tbl = document.getElementById('task_table').value;
	var id = document.getElementById('task_sysid').value;

	if(dateval =='')
	{
		alert("${JS:gs.getMessage('Date selection is required.')}");
		return false;
	}
	
	alert("REC:" + id + "\nTBL : "+ tbl+ "\nDATE SELECTED : "+ dateval+ "\nFIXED TIME : "+ fxtime);
	var ga = new GlideAjax('ReleaseNotify');
	ga.addParam('sysparm_name','setRelease');
	ga.addParam('sysparm_sys_id',id);	
	ga.addParam('sysparm_tbl',tbl);
	ga.addParam('sysparm_date',dateval);
	ga.addParam('sysparm_time',fxtime);
	ga.getXML(function getAnswer(response) {
		var result = response.responseXML.documentElement.getAttribute("answer");
		alert(result);
		if(result == false)
		{
			GlideDialogWindow.get().destroy();
			g_form.addErrorMessage("No deployment task exist. Make sure that all prior tasks are completed.");
			return false;
		}else{
			GlideDialogWindow.get().destroy();
			alert(result);
		}
	});

	//window.open('/'+tbl+'.do?sys_id='+id,'_self');
	//g_form.addInfoMessage('Items scheduled for release on ' + dateval);

}

Script Include:

	setRelease:function(){
		var rec = this.getParameter('sysparm_sys_id');
		var tbl = this.getParameter('sysparm_tbl');
		var dateval = this.getParameter('sysparm_date');
		var time = this.getParameter('sysparm_time');

		if(tbl == 'sc_req_item')
		{
			var sctask = new GlideRecord('sc_task');
			sctask.addQuery('active', true);
			sctask.addQuery('request_item', rec);
			sctask.addQuery('short_description', 'Deployment');
			sctask.query();
			if(sctask.next())
			{
				return 'Hello';
			}else{
				return 'Good Morning';
			}
		}

	},

Any idea why it's returning null instead of the expected 'Hello'/'Good Morning'?

@jiral 

Is your script include client callable?

Did you check script include is getting called or not?

try adding logs in script include & check

setRelease:function(){
var rec = this.getParameter('sysparm_sys_id');
var tbl = this.getParameter('sysparm_tbl');
var dateval = this.getParameter('sysparm_date');
var time = this.getParameter('sysparm_time');

gs.info("rec" + rec);

if(tbl == 'sc_req_item')
{
var sctask = new GlideRecord('sc_task');
sctask.addQuery('active', true);
sctask.addQuery('request_item', rec);
sctask.addQuery('short_description', 'Deployment');
sctask.query();
if(sctask.next())
{
return 'Hello';
}else{
return 'Good Morning';
}
}

},

It is.

I added gs.info("rec" + rec); but I'm not getting result. No info shows show up but got this alert

Got this one when validating the data to pass to the Ajax and this confirmed that the data are valid.

And here's the UI action where the UI page is called from

function showPage(){
	var gdw = new GlideModal('release_date',true);
	gdw.setTitle('Select target release date');
	gdw.setWidth(10);
	gdw.setPreference('table_name', g_form.getTableName());
	gdw.setPreference('sysid', g_form.getUniqueValue());
	gdw.render();
}

Found it. Seems like this part was the culprit:

initialize: function() {
},
