Hi! I’m wondering, is there a convenient “Jmix-way” to prevent invalid input in a TextField component, something like Vaadin’s textField.setAllowedCharPattern()? I’ve tried a MaskedField, but as I understand it doesn’t allow to enter an arbitrary number of characters. So should I use ValueChangedEvent to do the thing, or is there any more “automatic” way?
You can try to use TextChangeEvent with EAGER TextChangeEventMode.
In the handler, analyze the input. Warn or remove invalid characters.

Okay, thank you! So, I’ll do it manually.
