Hello everybody!!!
My team and I are developing a component like the one described as “Essentian Control 30” in this blog post → http://www.uxbooth.com/blog/essential-controls-for-web-applications/ or like the smart playlist builder in iTunes (see http://designingwebinterfaces.com/nested_clause_builde) but we are having problems by changing, adding, removing or repainting the components. When we change the value of a combo box, for example, a second component could change from text box to label or to another combo box but the new component is painted incomplete, depending on the size of the component that was there before.
Any advice to develop something like this?
