I am currently using NetAdvantage 10.3 ASP.NET, recently upgraded. This issue started happening when we upgraded.
If the site is on our test server the WebDataMenu does not display, you have to hit refresh in order for it to show up, side note: there is however a image next to the WDM that does show. If the site is run from Visual Studio then the WDM does not display and a javascript error prompt appears. There are two prompts that show, one when the page first loads and the second when you hit refresh. The two errors that show are:
Error: Sys.ArgumentUndefinedException: Value cannot be undefined.Parameter name: element
Error: Sys.ArgumentUndefinedException: Value cannot be undefined.Parameter name: handler
If I choose to debug them the following screenshot shows the error. If I debug the second error It shows the same bit of code but in a different place.
There does not seem to be a pattern to when the error occurs. It can happen when the opening page loads or it can happen when navigating through the site. Sometimes it works fine for awhile with out error and then sometimes it does it over and over for 4-5 times.
Any help or advice is highly appreciated. Let me know if i can provide any more information
Thank you
Hi,
if you could post your code zipped here I can take a quick look and help you. If the code contains proprietary information you can contact developer support and give them you sample project.
Thanks,

I put together a project consisting only a few files from the actual project that reproduces the error. It took me anywhere from 1 or 2 page refreshes to get the error to show to as much as 50+ refreshes for it to show so your experience may vary. The pages are very stripped down compared to what they normally are the wdm is populated by a couple listarrays defined in the codebehind instead of listarrays created from our database. The error still occurs though so I think this should help.
