    <p>I'm getting json data from an ajax call as shown below:</p> <pre><code>/* * Get list of vendors and populate table */ function getVendors() { $ .ajax({ async : true, type : "GET", url : "/JavaTestService/rs/TestService/getMVendors?version=2", dataType : "json", success : function(json) { //add element to vendors array $.each(json.resultSet.merchandiseVendor, function(index,item){ nameLocal = item.name; numberLocal = item.number; vendorData[vendorDataCounter] = { name : nameLocal, number : numberLocal } vendorDataCounter++; }); initVendorTable(); }, error : function(xhr, ajaxOptions, thrownError) { alert(xhr.status); alert(thrownError); } }); } </code></pre> <p>The initVendorTable() method is meant to populate a table with the data obtained from the above ajax call. initVendorTable() method shown below:</p> <pre><code>/* * Initialize the table containing the list of vendors */ function initVendorTable() { jQuery("#supplierTable").jqGrid({ datatype : "local", height : 250, colNames : [ 'Vendor Number', 'Vendor Name' ], colModel : [ { name : 'number', index : 'name', width : 200, sorttype : "int" }, { name : 'name', index : 'number', width : 200 } ], rowNum : 10, rowList : [ 10, 20, 30 ], sortname : 'number', viewrecords : true, sortorder : "desc", caption : "Suppliers" }); for(var i=0;i&lt;=vendorData.length;i++){ $("#supplierTable").jqGrid("addRowData",i+1,vendorData[i]); } alert(vendorData); } </code></pre> <p>I call the getVendors() method from a button click:</p> <pre><code>$(function() { $("#supplierSearchArea").dialog({ autoOpen : false, height : 400, width : 'auto', modal : true, title : 'Browse Suppliers' }); $("#supplierPopupButton").click(function(e) { $("#supplierSearchArea").dialog("open"); getVendors(); }); }); </code></pre> <p>The problem is that when I first click the button and the popup containing the table appears, the table is empty. This is because the array which I use to populate the table is empty.</p> <p>After stepping through the code, I've found that the initVendorTable() method gets called before the getVendors() method, even though I call the getVendors() method before the initVendorTable() method in the code. Is this an ajax quirk? Any suggestions on how I should work around this?</p>

    1. COI guess is because of asynchrounus nature of AJAX call

    2. COAh, gotcha. I changed async to false which generally solves the problem, but now the popup takes a pretty long time to load. Should I just throw up a loading gif?

    3. COI suggest to avoid using of sync call. Use promise or .done() instead

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
