Misbehaviour of scripts in Hub View

Hi All,

The scenario is like I have 2 account form (Parent-Child account). I am creating the cases from the child account form using subgrid of case entity.

Also, I have another subgrid on the Parent account form which is used to display all the cases which are made under the related child account record.

So for this, I implement a JS code to show all the cases made under the related child account on the Parent Account Form within another Case Subgrid.

Code is given below: -

function DisplayCases() {

// get Contacts Sub grid
var accountChildCasesGrid = window.parent.document.getElementById("CasesRelatedtoSites")

// Get the ID of the current account
var rootAccountID = Xrm.Page.data.entity.getId();

// Check that the subgrid is ready
if (accountChildCasesGrid == null){
setTimeout('DisplayCases()',1000);
return;
}

// Construct FetchXML for contacts in this account and its child accounts
var fetchXml = "<fetch version='1.0' mapping='logical'>";
fetchXml += "<entity name='incident'>";
fetchXml += "<attribute name='title'/>";
fetchXml += "<attribute name='customerid'/>";
fetchXml += "<attribute name='statecode'/>";
fetchXml += "<order attribute='title' descending='false' />";
fetchXml += "<link-entity name='account' from='accountid' to='customerid' link-type='inner' >";
fetchXml += "<filter type='and'>";
fetchXml += "<condition attribute='accountid' operator='eq-or-under' value='" + rootAccountID + "' />";
fetchXml += "<condition attribute='accountid' operator='not-null' />";
fetchXml += "</filter>";
fetchXml += "</link-entity>";
fetchXml += "</entity>";
fetchXml += "</fetch>";

// Layout of subgrid.
var LayoutXml = "<grid name='resultset' object='8' jump='new_name' select='1' preview='1' icon='1'>" +
" <row name='result' id='new_boat'>" +
"<cell name='title' width='100' />" +
"<cell name='customerid' width='100' />" +
"<cell name='statecode' width='100' />" +

"</row>" +
"</grid>";

// make sure control is ready and set data and refresh the subgrid
if (accountChildCasesGrid.control != null){
accountChildCasesGrid.control.SetParameter("fetchXml", fetchXml);
accountChildCasesGrid.control.refresh();
}
else{
setTimeout('DisplayCases()',1000);
}
}

So problem is only that this script is working as expected in standard view but not in Hub View.

Please suggest for the same.
