bug: iframe get request done 2x after ajax change in IE
We have a page that has an iframe and an ajax button.
When the ajax button is clicked, the iframe is replaced by a new iframe with
specific src.
We have encountered the phenomenon where the iframe src is requested
two times to the server after the button gets clicked.
After some debugging, the problem was pinned down and
lies within the file org\apache\wicket\ajax\wicket-ajax.js
The problem is within the function "replaceOuterHtmlIE".
There is some kind of "hack" to read the <script> tags within the received
html...
First the content of the div is filled with a table containing received ajax
component markup:
tempDiv.innerHTML = '<table style="display:none">' + text + '</table>';
This way script tags can be retrieved. Afterwards the innerHTML is replaced
by a div containing received text.
tempDiv.innerHTML = '<div style="display:none">' + text + '</div>';
Both statements cause IE to fetch the urls within the contained text (in our
case <iframe src="someurl"></iframe> tags).
We patched this the following way ...
The first occurence of tempDiv.innerHTML, The content of the div is filled
with a table containing a div.
tempDiv.innerHTML = '<table style="display:none"><div
style="display:none">' + text + '</div></table>';
After the script tags are retrieved, the table gets removed from the
structure,
and the div within the table is connected to tempDiv.
var table=tempDiv.firstChild;
var childDiv=table.firstChild.firstChild;
tempDiv.removeChild(table);
tempDiv.appendChild(childDiv);
Would it be possible to apply this patch to the next wicket version?

Can you please create a jira issue with this? I have to test first if
the fix doesn't break other things.
