Please do so. However, it opens up the concept of changing the way components render. Perhaps more components should act like PropertySelection, and have a delegate used to perform rendering (with a shared instance used in most cases). You could then create standard Foo's with an alternate FooRenderDelegate to accomplish what you want.
On the other hand, what you really want is to do a little thing to TextField and have it affect all TextField's in your app. I guess, in the world of HotSpot, adding additional empty methods will not cause an issue; HotSpot will inline the method calls to nothing (unless you actually do override the empty method in a subclass). Are you sure there isn't a CSS way to do this? I forget how CSS references input fields. -- [EMAIL PROTECTED] http://tapestry.sf.net > Hi Howard - > > Yours suggestions of using inheritance for my own text field worked great. > However, I also wanted to the same behavior in Radio, PropertySelection, > Select, TextArea and Checkbox.
