Issue Found: Odd Behavior in Master Page

I found an issue with how ASPDNSF reads the master page file.

I added the following into the head section of the master page....

Code:

    <script type="text/javascript">
    <!--
        function openWindow(URL, windowName, windowFeatures) {
            newWindow = window.open(URL, "windowName", windowFeatures);
            newWindow.document.write('<html><head><title>' + windowName + '</title></head><body bgcolor=ffffff leftmargin=0 topmargin=0 marginheight=0 marginwidth=0><img src=' + URL + '></img></body></html>');
        }
    //-->
    </script>

And received the following error:

Code:

Page URL:/t-media.aspx
Source:System.Web
Message:You can only have one <title> element within the <head> element.

ASPDNSF seems to be judging html tags even when they are included in javascript, so to test this i added seperation in the tags(code below) and it worked fine.

Code:

    <script type="text/javascript">
    <!--
        function openWindow(URL, windowName, windowFeatures) {
            newWindow = window.open(URL, "windowName", windowFeatures);
            newWindow.document.write('<ht' + 'ml><he' + 'ad><tit' + 'le>' + windowName + '</tit' + 'le></he' + 'ad><bo' + 'dy bgcolor=ffffff leftmargin=0 topmargin=0 marginheight=0 marginwidth=0><img src=' + URL + '></img></bo' + 'dy></ht' + 'ml>');
        }
    //-->
    </script>

We'll investigate this and post a reply about this matter shortly. Thanks for posting.

That's actually a .NET master page problem, not the software. There's a good bit of information on this online. It's trying to parse the page contents and sees the extra head and html tags in there and gets thrown off. The solution is the one you already found - break up the strings so the master page doesn't read them as new tags and the issue goes away.
