问题 Our application uses the Ext.grid.Panel to display rows of data. When the user clicks a "New..." button we are adding a new record to the grid store. Everything is working fine. However, on certain fields, of just this new (as of yet) unsynced records, we would like to display specific empty text within certain cells. For example: 'Enter title here' or 'Choose a platform".

问题 We have a huge amount of applications which all are sharing some parts (data/backend/frontend). Users may have access to one or more applications and currently the user need to load them one by one. Our Customer don't like this so we are now refactoring all into one huge application where the client itself resolves which module to load. First test looked good and due to our custom modulebuilder tool the loading times are at a min. Now I stumbled over the new Ext.app.EventDomain and wondered
