How to do wall post in WAP based facebook mobile app?

Question

I'm doing a facebook application for (WAP based)mobile browser. I need to show the post dialog. When i use the following code for wall post it show error.

http://m.facebook.com/dialog/feed?app_id='.$app_id.'&redirect_uri=$redirect_url&display=wap

The error is:

API ERROR CODE:3
API Error Description: Unknown Method
Error Message: This method isn't supported for this display type

While I give display type as 'touch' in the above mentioned URL it works fine in the touch devices. But no form displayed in the wap browser.

That's strange, because their documentation does mention that is the method to do it: http://developers.facebook.com/docs/reference/dialogs/

I notice an error in your PHP though (unclosed apostrophe):

It should be:

'http://m.facebook.com/dialog/feed?app_id='.$app_id.'&redirect_uri='.$redirect_url.'&display=wap'

Here is a similar issue on https://github.com/facebook/facebook-android-sdk/issues/177

Also, check out facebook's bug tracker: http://bugs.developers.facebook.net and perhaps file your bug there and then link to it from here.
