scheduler.attachEvent - onXLE - Type mismatch error on F5 Re


My project has been working fine but now, out of the blue, when I press F5 to refresh a page I’m getting an error:

htmlfile: Type mismatch.

It’s happening in this function from dthmlxScheduler.js:

scheduler.attachEvent(“onXLE”, function () {

var A;

if (A = this.config.show_loading) {

this._obj.removeChild(A); <<<----------- happening here ******

this.config.show_loading = true



If I select to Continue, then the program continues on but the loading animated GIF continues going.


Here is my code that configures and calls the Scheduler:

scheduler.config.xml_date = “%Y-%m-%d %h:%i%a”;

scheduler.config.default_date = “%M %d, %Y”;

scheduler.config.month_date = “%M %d, %Y”;

scheduler.config.day_date = “%D, %M %d”;

scheduler.config.hour_date = “%h:%i%a”;

scheduler.config.readonly = true;

scheduler.config.details_on_dblclick = true;

scheduler.config.lightbox.sections = [

         { name: “description”, height: 130, map_to: “text”, type: “textarea”, focus: true },

         { name: “time”, height: 72, type: “time”, map_to: “auto” }


scheduler.config.date_step = “7”;

scheduler.config.multi_day = true;

scheduler.config.drag_create = false;

scheduler.config.drag_move = false;

scheduler.config.drag_resize = false;

scheduler.config.dblclick_create = false;

scheduler.config.show_loading = true;

scheduler.config.icons_edit = [“icon_cancel”];

scheduler.config.icons_select = [“icon_details”];

scheduler.locale.labels.icon_delete = “”;

scheduler.locale.labels.icon_save = “”;

scheduler.locale.labels.icon_edit = “”;

scheduler.init(‘scheduler_here’, null, ‘month’);


scheduler.attachEvent(“onClick”, function() {

return false;



My schedulerData.aspx page simply returns data from a stored proc that’s been put into proper XML format.

I’m really not sure how is such situation can occur.
Please try to use the attached js files - each of them contains different updates , which are related to described situation. (19.6 KB) (19.6 KB)

That seemed to help some.

The error is going away but the animated GIF is still there after I press F5 or if the user is redirected back to the page.
