In recent years we have developed a tool to create and manage RIA application without writing code. It uses PHP 5.3 on server and produces html pages (Ajax compliance) as user interface. The tool consists of 2 objects: the generator and the runtime. Development takes place through the code generator in a completely visual, the runtime interprets as described by the generator, taking care of interfacing with the database, executing the instructions (logic executive) and producing user interfaces (Ajax). We need to solve 3 issues on runtime. 1. Make compatible our control combobox / listbox with mobile systems (iPad/ Android) 2. Improve our DBGrid (ajax) which shows some refresh problems during user interaction (change of line, page down, etc..) 3. Changing the default behavior of our windows that currently are opened always cascade(modal). This behaviour produces rich pages thus slowing down the navigation. It would be best to work hiding underneath the windows, leaving visible only the active window (top level).
