Hi fellas,

I have multiple Windows defined on my page like so:

<% Html.Telerik().Window()
        .Visible(false)
        .Name("MyWindow")
        .Title("My Window")
        .Content(() =>
        { %>
<iframe src="<%= Url.Action("_MyWindow", "mycontroller", new { routeParam = Model.something }) %>" style="width: 100%; height: 100%;" frameborder="0"></iframe>
<% })
        .Draggable(true)
        .Buttons(b => b.Close())
        .Scrollable(false)
        .Width(500)
        .Height(221)
        .Modal(true)
        .Render();
%>

The problem I'm facing is when I open one of the windows, about 5-10% of the time, content from the incorrect window will get loaded. Basically, the content from window "A" gets loaded into window "B". It's nearly impossible to put my finger on what's causing it... it appears to be completely random. Refreshing the page often fixes it, but not always.

Any ideas on what could be causing this? I'm willing to put together an example if necessary.

Hello Derek,

Does this happen with the service pack? If not, can you please provide the sample project?

YES, I installed the latest service pack and it still happens. Please download the sample solution below to see the error in action. I've included steps to reproduce it on the home page. I hope that you can tell me what's wrong.

Example solution

Hello Derek,

Thank you for the attached test project.

Unfortunately, I was not able to reproduce the problem locally. Could you please check this screencast, which I made when testing the test application?

Let me know if I am missing something.

Georgi,

Thanks for taking a look at this.

You seem to be clicking everything in the correct sequence. I'm now thinking this may be a Firefox specific issue. Please see this screencast for my experience with the same exact project (I deleted it and downloaded it from this forum post just to be certain).

Thanks,

-Derek

Some more screencast crazyness to check out. Note how the iframe is pointing to the correct URL, but it's contents is incorrect. It's like seeing a ghost!

Hello Derek Hunziker,

I was able to reproduce the depicted issue. It seems that I have stopped caching in the browser, which resolve the aforementioned problem.

Unfortunately this seams to be problem related with FF 3+ and the only solution, which I was able to find is explained in this post.

I have modified your test project in order to resolve the depicted issue.
