Using the output element with mediatype attribute set as 'image/png' and an appropriate value for the value attribute doesn't work.

Reproducible: Always

Actual Results:  
Nothing is displayed

Expected Results:  
An image should be displayed

It is an very useful feature for generating charts (with Google charts) on the fly.

Attachment: make non-bound xf:output with images work

When doing no bind, @typelist is not set. This causes the image not to be displayed. This patch assumes that, if the node is not bound, a URL is given in @value and displays it.

might be worth to change the line above instead otherwise it's not needed.

I was hesitant about this variation on using @value, but as Philipp pointed out to me, it is already supported by Orbeon (http://www.orbeon.com/ops/doc/reference-xforms-guide#xforms-relative-paths-image-mediatype).  And it does make sense.

I've asked Philipp to follow up with the W3C to see if this Orbeon behavior (treating @value as anyURI if @mediatype present) is specific to images or if any mediatype value is provided.

What is result of discussion? Should I put the patch to mercurial?

Comment 10

[aaronr]

I thought the result was that we would back out this patch from cvs.  Philipp, do you agree?

Comment 11

[Philipp Wagner [:imphil]]

Yes, the WG does not seem to have really decided what to do with that syntax and thus it's probably best to back it out to avoid that people rely on that extension.

Comment 12

[Philipp Wagner [:imphil]]

This bug never made it into hg trunk and the XForms WG seems to discourage this usage, so let's close it.
