Trouble using UI Action variables in UI page

[Andrew158]

Hi Everyone, 

I have a UI Action button that opens a UI Page in a glide dialog window. My UI Action script is as follows:

function openUIPage(){	
	try{
		var floorid = g_form.getValue('floorid');
		if (floorid != ''){
			var ga = new GlideAjax('Check_Floorplan');
			ga.addParam('sysparm_name', 'checkFloorplan');
			ga.addParam('floorid', floorid);
			ga.getXML(function(response) {
				var answer = response.responseXML.documentElement.getAttribute('svg');
				if(answer == 'true'){
					var gdw = new GlideDialogWindow('x_admis_floorplan_Room_Picker');
					gdw.setPreference('sysparm_test', 'abc123'); 
					gdw.setTitle('Room Picker');
					gdw.setSize(900, 900);
					gdw.render();
				}
				else{
					alert('No floorplan was found for the selected floor');
				}
			});	
		}else{
			alert('Please select a floor first');
		}
	}catch(e){
		alert(e);
	}
}

And in the HTML of my UI Page, I have the following code:

<g:evaluate var="jvar_test">
var sysparm_test = RP.getParameterValue("sysparm_test");
sysparm_test;
</g:evaluate>
Test: ${sysparm_test}

I have also tried this HTML:

<g:evaluate var="jvar_test">
var sysparm_test = RP.getWindowProperties().get("sysparm_test");
sysparm_test;
</g:evaluate>
Test: ${sysparm_test}

However, it seems that no matter what I try, the value of ${sysparm_test} is always null. I have also tried replacing ${sysparm_test} with ${jvar_test}, and the result was the same. How can I access the value of these GlideDialogWindow preferences in my UI Page?

Thanks,

Andrew

Hello @Andrew158 ,

Try this 

<g:evaluate var="jvar_test" expression="RP.getParameterValue('sysparm_test')"/>

Hope this helps 

Mark my answer correct if this helps you

Hello Mohith,

Thanks for the response. I have tried with the updated HTML: 

	<g:evaluate var="jvar_test" expression="RP.getParameterValue('sysparm_test')"/> 
	Test: ${jvar_test}

and unfortunately got the same result of null.
