pageLoad fires before script references are loaded

I have an aspx page with:

- a scriptmanager that has 2 script references. Both scripts have the "if (typeof(Sys) !== 'undefined') Sys.Application.notifyScriptLoaded();" line at their end.

- a script section with a pageLoad function that calls a function defined in one of the 2 script references.

- an iframe (with src set to about:blank).


I get an "object undefined" error in the pageLoad function. with fiddler and in the debugger I can see that my script rerefences have not yet been loaded. As fas as I know, they should! It always worked until we added the iframe control. Removing the iframe control resolves the problem. To me this looks like an error in ajax where the pageLoad is executed on the load of the iframe contents instead of on the load of the main page.

Anyone any suggestion?

Could you share some code that reproduces this bug? I was unable to get the behavior you describe.

Are you using a function named pageLoad? Or Sys.Application.add_load(...)? Or Sys.WebForms.PageRequestManager.getInstance().add_pageLoaded(...)? Code would help a lot.

Thanks for looking into the problem. I will try to assemble a minimal solution that exposes the bug. BTW: it is a pageLoad function. In the debugger I saw that Ajax in the onload event looks if it exists and, if so, calls it. That's also how I found out that it gets called twice from this event handler. Give me some time to assemble the solution.

Thanks agian,
