Halp...

Hi, Im playing with clickable images in 1.10pre1 and I try:
----------- vv -----------
<html>
<head><title>Oh crap</title></head>
<body>

<al-form method="post">

<al-input type="image" name="pos" src="http://10.0.0.254/cgi-bin/20/map_image" whitespace>

<al-input type="submit" name="submit" value="never!">

</al-form>
</body>
</html>
----------- ^^ -----------

which generates some thing like (neatened):
----------- vv -----------
<html>
<head><title>Oh crap</title></head>
<body>

<form method="post" action="/cgi-bin/20">

<input type="image" src="http://10.0.0.254/cgi-bin/20/map_image" name="pos">

<input type="submit" name="submit" value="never!">

<input type="hidden" name="__albform__" value="eJzLkl9YfuDO1a06y2cGbxZYUFlbyKgRylZcmpSbWVLI5M0QylyQX1zI7M1QqgcAnRIQMw==">

</form>
</body>
</html>
----------- ^^ -----------

but when I click on the image, I get:
----------- vv -----------
Template traceback (most recent call last):

Traceback (most recent call last):
  File "/usr/lib/python2.1/site-packages/albatross/app.py", line 221, in run
    self.merge_request(ctx)
  File "/usr/lib/python2.1/site-packages/albatross/app.py", line 301, in merge_request
    ctx.merge_request()
  File "/usr/lib/python2.1/site-packages/albatross/context.py", line 279, in merge_request
    text = self.request.field_value('__albform__')
  File "/usr/lib/python2.1/site-packages/albatross/cgiapp.py", line 26, in field_value
    if isinstance(field, list):
TypeError: isinstance() arg 2 must be a class or type
----------- ^^ -----------

Which doesnt look like it's in my code at all. :-/ (or if it is, how
to I get a real traceback or some more useful feedback?)

Infact clicking on the submit button also generates the above error.
Hmmm?

Its probably a problem in my actual code, but it's kinda hard to find
it with the above traceback (which makes it look like an albatross
internal problem). ??

cheese :),
