Why can't I derive the "Button" style from a custom style?

[timo.v...@gmail.com]

When I create a style named "Button" and configure it explicitly to derive from "MyButton", buttons are not displayed in the MyButton style.

Is there a constraint about overriding standard styles, or am I doing something wrong?

(My assumption is that disabling "Override Attribute" and entering "MyButton" should make the "Button" style identical to "MyButton".)

Ok, I already found out that overriding a style like "Button" is very dangerous, as it is e.g. used within an OnOffSwitch component.

The better solution is to set the UIID of all buttons to "MyButton".

The older buttons have some "magic" properties at the base. It sucks but its really hard to fix. We suggest using your own styles and not going overboard with inheritance for those cases.
