Hello Derrell, All model properties don't have the fallback to its value. What is clear is, that we need to supply a possibility to specify a different model than its value. But I don't know if we need a fallback to the value / label. All other widgets not having the model property use the value so you don't run into that problem.
The only widgets with the model property which could have that fallback are: qx.ui.form.RadioButton qx.ui.menu.RadioButton qx.ui.form.CheckBox qx.ui.toolbar.RadioButton qx.ui.form.ListItem qx.ui.tree.AbstractTreeItem The first group could have its value as fallback. So you get 'true' or 'false' as model if no model is specified. But how do we know that no model is specified? Perhaps someone would like to have null as model? Imagine a set of radio boxes with the first one showing "no thanks" or anything like that. The same is true for the second group where it becomes the label instead of the value. What do you think? I'm not sure which situation is worse. Either you can not specify null as model or you have no fallback!
