Ensure that the document parent can always be updated (regardless of skin rendering)

This should apply to any 1.* release:

It looks like the DocumentInformation panel depends on being rendered inside the edit form. In a skin I have, the main content (including the form) is completely rendered before the sidebar, and the sidebar is what renders the panels.

The following change to the DocumentInformation Panel corrected the problem:

Instead of :

<dl><dt><label for="xwikidocparentinput2">$msg.get("parentfield"):</label></dt> <dd><input type="text" id="xwikidocparentinput2" name="parent" value="$!tdoc.parent" size="30" /></dd>

Do this:

<dl><dt><label for="xwikidocparentinput2">$msg.get("parentfield"):</label></dt> <dd><input type="text" id="xwikidocparentinput2" name="parent" value="$!tdoc.parent" size="30" onChange="updateParent(this); return false;"/></dd>

(add a call to a javascript on the parent input field: onChange="updateParent(this); return false;")

The script:

function updateParent(field) {
var editForm = document.getElementById('edit');
if(!editForm || !field) return;
editForm.xwikidocparentinput.value = field.value;
alert(field.value);
alert(editForm.xwikidocparentinput.value);
}

Requires the hidden field for the parent to be re-added. I put it in edit.vm, so that it present in any edit mode:

<input type="hidden" id="xwikidocparentinput" name="parent" value="$!tdoc.parent"/>

Something similar should be done for tags, as that update will have the same issue. I haven't had the time to figure out how they work yet.. the tagedit.vm template is pretty obscure.
