[Xsltforms-support] The <xf:delete> does not delete the 1st node of <xf:itemset> bound by a <xf:sel

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

I think there is a problem with using the <xf:delete> to delete
instance-nodes bound to <xf:itemsets> of <xf:select> or <xf:select1>
controls.
(lets say to clean-up the selection-lists)

Although the <xf;delete> properly erases the instance-document contents,
the seletion-lists are not updated corretly,
and the first item is always visible in the select controls.

Is this indeed the expected behavior?

- Reported against XSLTForms release:
  beta-2
- I tested and got the same behavior on browsers:
* firefox 3.5,
* chrome 4
* ie8

- Also checked on Chrome revision-364 from svn and found the situation
slightly worse:
The <xf:select1> control preserves the old buggy behavior but the
<xf:select> does not remove *any* item of it selection-list items,
keeping it intact!

An xform that demonstrate the problems is attached,
and also included below for reference.

      When trigger clicked, should it had deleted all nodes from

      <br />
      Or it is ok for the selection-list to still contain the first-one
      node??
