Support
#1

My jmix version: 2.1.0

How can I validate in list-view:
I want to validate some fields in the list-view screen, i already tried to generate default handler such as
OperationChangeEvent, ComponentValueChangeEvent, validator and all of them cant work
image

@Subscribe("ccyCodeField")
    public void onCcyCodeFieldOperationChange(final PropertyFilter.OperationChangeEvent<?> event) {
        
    }

and I got

DevelopmentException: Unable to find @Subscribe target ccyCodeField in GdCurrencyListView

@Subscribe("ccyCodeField")
    public void onCcyCodeFieldComponentValueChange(final AbstractField.ComponentValueChangeEvent<PropertyFilter<?>, ?> event) {
        
    }

and I got

DevelopmentException: Unable to find @Subscribe target ccyCodeField in GdCurrencyListView

@Install(to = "ccyCodeField", subject = "validator")
    private void ccyCodeFieldValidator(final Object t) {
        
    }

and I got

DevelopmentException: Unable to find @Install target for method private void com.fis.pbcapcore.view.gdcurrency.GdCurrencyListView.ccyCodeFieldValidator(java.lang.Object) in class com.fis.pbcapcore.view.gdcurrency.GdCurrencyListView

all of them are default generate handler

You are trying to subscribe to components dynamically created by genericFilter - it’s impossible.

If you need to validate filter input, use dedicated input controls like in the following example: Custom filter using declarative conditions.
