[OpenLayers-Users] Problems using Layer.WMS.Post

[Andreas Hocevar]

Hi,

please use a current trunk version of OpenLayers, not a patched 2.8
version. You can download a nightly build from
http://trac.openlayers.org/wiki/HowToDownload

Regards,
Andreas.

Maybe I didn't mention, but it works in FF, Chrome and Safari, the only problematic browser is IE, which has the limitation I mentioned. Digging a little bit in the code I found that an OL class was missing to get WMS.Post work. This class was IFrame.js, but know I've got another error pointing this class:

Again, digging into the code I found that the class Util.js doesnt' have the function urlAppend, and I've started wondering how many classes do I have to update to make this work. Are there some instructions to apply this change or some info about the classes involved in this change??

I followed up the discussions about this solution and decided to apply it to my app. But I get an error when I try to apply an SLD and make it visible. I mean, I create the layer without any error:
