It's been a while since I've written any WML and seem to remember this was a known problem a few years ago.
If I have a page (say test.wml) which contains a form which posts the results back to itself, the submit button just doesn't work.
To get around this, I amend the target URL as follows with a random number to make it work:
<go href="test.wml?dummy=random123423" method="get">
Is there a better way around this? I'm using the following cache tags, if it's important:
<meta forua="true" http-equiv="Cache-Control" content="max-age=0" />
