Read Only Field Editor Screen v7.1

Support
#1

Hello,

I feel like I am making this way more complicated than it needs to be, and I am starting to spin my wheels.

I have two fields for date

dueDate and extendedDueDate

I would like to make the dueDate field read-only if there is already a value in it on the editor screen. This would force the user to use the extendedDueDate field.

I tried to simply put this in the Java edit screen

    if (dueDateField != null) {
    dueDateField.setEditable(false);
    extendedDueDateField.setVisible(true);
} else {
    extendedDueDateField.setVisible(false);
}

This kind of worked, but would make the dueDate field read only on job creation too not allowing any values.

I then attempted using
https://doc.cuba-platform.com/manual-latest/entity_attribute_access.html

I created a new bean

and tried this code but the dueDate field is still editable.

import org.springframework.stereotype.Component;
import com.company.hermes.entity.Job;
import com.haulmont.cuba.core.app.SetupAttributeAccessHandler;
import com.haulmont.cuba.core.app.events.SetupAttributeAccessEvent;
import org.springframework.context.event.EventListener;

//@Component(JobAttributeAccessHandler.NAME)
@Component("JobAttributeAccessHandler")
public class JobAttributeAccessHandler implements SetupAttributeAccessHandler<Job> {
    //public static final String NAME = "hermes_JobAttributeAccessHandler";

    @Override
    public boolean supports(Class clazz) {
        return Job.class.isAssignableFrom(clazz);
    }

    @Override
    public void setupAccess(SetupAttributeAccessEvent<Job> event){
        Job job = event.getEntity();
        if(job.getDueDate() != null){
            event.addReadOnly("dueDateField");
        } else {
            event.addHidden("extendedDueDate");
        }

    }
}

What am I missing?

Hi @Stephen,

Try something like this:

@Subscribe
public void onAfterShow(AfterShowEvent event) {
    if (this.getEditedEntity().getDueDate() != null) {
        this.dueDateField.setEditable(false);
        this.extendedDueDateField.setVisible(true);
    } else {
        this.extendedDueDateField.setVisible(false);
    }
}

Works! - I knew I was overthinking it.

Thank you so much!
