The error you are receiving states that somewhere on your javascript code you are trying to access to an attribute of an object that's not loaded on the moment is being accessed.

You should check that 598 line on your FormasLib.js file and seek where dialogWin object is loaded, maybe the code where that object is defined is not being executed when you make the call from server code.

Hi

Attached is the function that causes the error. I marked line 598. How do I make sure the code is executed before I make a call to the server code?

// Generate a modal dialog.
// Parameters:
// url -- URL of the page/frameset to be loaded into dialog
// width -- pixel width of the dialog window
// height -- pixel height of the dialog window
// target -- window name where to load
// scrollbars -- include scrollbars in window?
// isResizable -- is window resizable?
function openModalDialog(url, width, height, target, scrollbars, isResizable, isExternal, status)
{
dialogWin = new Object()

// Initialize properties of the modal dialog object.
dialogWin.returnedValue = ""
dialogWin.url = url
dialogWin.width = width
dialogWin.height = height

var external = false ;
if ( typeof(isExternal) != "undefined" && isExternal != null )
external = isExternal;

if ( scrollbars == null || !scrollbars )
dialogWin.scrollbars = 0
else if ( scrollbars == "true" )
dialogWin.scrollbars = "yes"
else
dialogWin.scrollbars = scrollbars

if ( isResizable == null || isResizable )
dialogWin.resizable = "yes"
else if (!isResizable || isResizable == "false")
dialogWin.resizable = "no"
else
dialogWin.resizable = isResizable

if ( status == null || !status )
dialogWin.status = "no";
else if ( status == "true" )
dialogWin.status = "yes";
else
dialogWin.status = status;

// Keep name unique so Navigator doesn't overwrite an existing dialog.
dialogWin.name = target

if ( target == "" || !target )
dialogWin.name = (new Date()).getSeconds().toString()

// Assemble window attributes and try to center the dialog.
if (Nav) {
// center in screen.
dialogWin.left = window.screenX + ((window.outerWidth - dialogWin.width) / 2)
dialogWin.top = window.screenY + ((window.outerHeight - dialogWin.height) / 2)

var attr = "screenX=" + dialogWin.left + ",screenY=" + dialogWin.top

attr += ",width=" + dialogWin.width + ",height=" + dialogWin.height + ",resizable=" + dialogWin.resizable + ",scrollbars=" + dialogWin.scrollbars + ",status=" + dialogWin.status
} else {
// center in screen.
dialogWin.left = (screen.width - dialogWin.width) / 2
dialogWin.top = (screen.height - dialogWin.height) / 2

var attr = "left=" + dialogWin.left + ",top=" + dialogWin.top

attr += ",width=" + dialogWin.width + ",height=" + dialogWin.height + ",resizable=" + dialogWin.resizable + ",scrollbars=" + dialogWin.scrollbars + ",status=" + dialogWin.status
}

if (dialogWin.url == null || dialogWin.url== ""){
                  var frm = getForm('');
                  var objurl = "";
                  if(frm) {
                        if(frm.objid && frm.classid && frm.tabid) {
                              objurl = "?objid="+frm.objid.value+"&classid="+frm.classid.value+"&tabid="+frm.tabid.value;
                        }
                  }
                  if(objurl.length > 0) {
                        dialogWin.url = "PopupLoading.jsp"+objurl;
                  } else {
                        dialogWin.url = "PopupLoading.jsp";
                  }
}

// Generate the dialog and make sure it has focus.
dialogWin.win = window.open(dialogWin.url, dialogWin.name, attr)

// need these for Solaris
if (typeof is_sun == "undefined") is_sun = (navigator.userAgent.toLowerCase().indexOf("sunos")!=-1);
if ( is_sun && dialogWin.win && !external)
{
dialogWin.win.resizeTo(dialogWin.width,dialogWin.height);
dialogWin.win.moveTo(dialogWin.left,dialogWin.top);
}

Line 598 dialogWin.win.focus()
}
