FXML does not allow the use of a custom component without constructors that it accepts but there are some pre-built custom components that can only be produced by a factory. An example is a
clearable textfield in controlsfx.
Without datafx flow, one can create a
custom builder factory and attach it to an FXML loader. Since users are abstracted away from FXML loaders in datafx flow, this is not possible when the API is used. Is there a way to attach a custom builder or solve this problem in datafx flow?
