Changing Control Type
If you need a different control from the one you placed on the canvas, rather than delete the control and drag another one from the Palette view, you can change the control type directly from the design canvas.
If you click a control type that is not compatible with the current control, Composite Application Framework disables the OK button.
To change the control type on the design canvas
1. In the UI Development Perspective, in the design canvas, select a control in a view.
2. Right-click the control to changed and click Change Control Type
3. In the Control Type Editor, select the new control type from the tree view, and then click OK.
