I don't know if that is the right place to ask the question. So I have a sencha touch 2 application which is working fine in google chrome. I am using a n html page as login page where i pass four attributes to the server to get a response. In chrome that is working without problems. As soon i want to test it on an iPhone or android emulator i get a white screen after i send the form. I checked the response on the server side and i saw that the values from the form are not send to the server. But why i don't know.
