Problem Description:  When trying to use any ColdFusion.grid related function in a function that is called by ajaxOnLoad, the grid object is not available.  This worked in Coldfusion 10.

Steps to Reproduce:  Here is the code to reproduce:

		<script type="text/javascript">
	var aproxy;
	var tb;
	var grid;
	function initPage()
		grid = ColdFusion.Grid.getGridObject('testGrid');
    	grid.on('mouseover', mouseOver);	
    	//tb = ColdFusion.Grid.getTopToolbar("openSolicitations");
	//tb.add({text:"Open Solicitations"});
	function mouseOver() {

<cfform id="testForm">
			<div id="stylized">
				<div class="mybody" style="margin-bottom:10px;">
			<h3>Test page
<cfgrid name="testGrid" 
	format="html" rowheight="100" title="Test Grid" 
		colheaderalign="left" align="middle" >
	<cfgridcolumn name="PERSON_ID" header="Name" width="150" dataalign="left"/>
	<cfgridcolumn name="LAST_NAME" header="Description" width="450"/>
	<cfgridcolumn name="FIRST_NAME" header="Open Date" width="110"/>

<button onClick="initPage()">Test</button>

<cfset ajaxOnLoad("initPage")/> 

Actual Result:  Javascript error:  TypeError: grid is undefined

Expected Result:   Grid object should be available at this point.

Any Workarounds:  Stay at Coldfusion 10.

The "Test" button does work, which calls the same function.

Hi Yodeler, Can you please try wrapping the references to the grid objects within Ext.onReady method, like so: function initPage(){ Ext.onReady( function(){ var grid = ColdFusion.Grid.getGridObject('TestGrid'); }); } Refer :!/api/Ext-method-onReady

Thanks for the quick reply. Ok, that works, though it would be nice to have this in the Coldfusion documentation since the way I had it worked in Coldfusion 10. Now how do I get around the relative positioning of the columns in the grid with the ExtJS upgrade? The columns start with the first column of data returned from the bind, not the first column defined with cfgridcolumn. Thanks.

Yodeler, The column data mismatch issue is logged as bug #CF-3712885. It is fixed and the fix shall be made available in the next product update. About this bug, wrapping the grid references in Ext.onReady is only a workaround for now. We expect this to be fixed as well in the next update. Thanks.

This issue was fixed for ColdFusion.Grid functions, but not for ColdFusion.Layout functions. Filed CF-3914318 for ColdFusion.Layout functions. Thanks!, -Aaron
