Setting ‘null’ causes “Too much recursion” in Firefox Posts

July 29, 2013 at 8:54 pm Setting ‘null’ causes “Too much recursion” in Firefox #25907

Participant

I am using the DateTimeInput control on an entry form that is reset to a blank entry before later being (optionally) filled with a value from the database.

As per the API documentation, I set the control to a blank entry by sending a “null” value:

$(‘#Calendar’).jqxDateTimeInput(‘setDate’, null);

This works great, and I’m not having any problems with it on Google Chrome or Internet Explorer. However, in Firefox, the control sets to “null” correctly the first 2 -3 times, but after that, Firefox throws a “Too much recursion” exception message in the Web Console.

I’m using jqxWidgets version 2.9.3, Firefox version 22.0 and jQuery version 1.10.2 .

Hi DLadner,

I am pretty sure that this would never happen if you close the browser’s debugger.

Hi Peter, unfortunately I am seeing it happen in Firefox even without the debugger open. I don’t see the ‘Too much recursion’ error of course, but script execution halts at the “setDate” line of code.

Hi DLadner,

I am sorry, but using FF 22.0 and jQWidgets 2.9.3, I cannot reproduce such behavior.

Here’s my test sample:

                // Create a jqxDateTimeInput
                $("#jqxWidget").jqxDateTimeInput({width: '250px', height: '25px', theme: theme});
                $("#button").click(function () {
                    $("#jqxWidget").jqxDateTimeInput('setDate', null);
                });
            });

I was unable to reproduce it with your code Peter. My page is complex, so there must be something buried within the complexity that is causing the error.

I was able to work-around the Firefox error by using setTimeout:

window.setTimeout(“$(‘#Calendar’).jqxDateTimeInput(‘setDate’, null);”, 5);

With this code, I no longer get the “Too much recursion” error.
