问题 I have finally managed to create a production build of my sencha web app using Cmd 3.10.2.342 and touch 2.2.1 All my bespoke files are included and deltas are created as one would expect.

问题 we're currently developing an application that makes extensive use of popup windows(*) and have run into an issue on IE (this has been reported before but I couldn't find any solution). The problem is this: our main window M opens a popup window P and keeps a reference to it. P then registers an event handler on an object in M . When the event fires, IE8 bombs out with the following error message: JScript object expected ext-all-debug.js (Line 1735, Char 17) Code: 0 which is the fire-function

问题 I am trying to post a form to an iframe. my issue is that my form gets posted just fine when I render the iframe to body. But the issue with this is that the container displays at the bottom of the page instead of the place where I want it to show. If I don't use the renderTo property, my form never gets posted to iframe at all.

问题 I'm having an issue where I pop up a window with a loaded comboBox, and when I click on it, the fields show up behind the window. Thinking I may be using some setting wrong, I created a small test based off the documentation of the ComboBox, and it does it here for me as well.
