It appears the 3.2 has regressed a previously working enhancement to be able to select a specific view via url. For example, going to /email@example.com would take you directly to the compose page with the to address prefilled. This appears to no longer work in the 3.2 beta 2 release.
I believe this was #6891 in bugzilla, which oddly was never marked closed or resolved but worked none-the-less in 3.1.1 onward. Did the parameters change? I hope its that simple because this is a very important feature for us and would repressent a major setback were it no longer functioning.
We *also* were using ZmComposeController.doAction() at another point to change the view and this also seems to no longer work. So it may not be the parameter, but something else thats no longer working.
