Property depending on path property not refreshed after Browse dialog closes [message #1121299]

Hi,

I have a path property with browse button and one disabled property that should refresh it contents based on value from path property. The disabled property is defined with @Enablement(expr = "false") annotation and has @DependsOn annotation that points to the path property. The path property has validation service with side-effect changing the value of the disabled property - not directly but on the underlying resource.
When I type into the path value (without using browse button) the new value from resource is refreshed after the validation service is called (through ValuePropertyBinding.read). But when browse button is used to change the path value, the ValuePropertyBinding.read is not being called after the validation service call which damages the data integrity between model and resource.
Is this a bug or am I supposed to do something else here?

I would guess that you are hitting the case where validation service doesn't change property validation. That means no validation event is triggered, so @DependsOn doesn't perform a refresh on the dependent property.

Rather than using @DependsOn, you can do one of the following...

1. Have the resource refresh the property when underlying data is changed. This is the preferred option.

2. Have the validation service call refresh on the property after changing its underlying data.

In your 'init' of your validation service, you need to attach listeners to the properties that you are interested in. Then when the listener fires you just call 'refresh()'. And the property that this service is attached to will get revalidated.

See here: https://github.com/liferay/liferay-ide/blob/master/tools/plugins/com.liferay.ide.project.core/src/com/liferay/ide/project/core/model/internal/PortletFrameworkValidationService.java

In that example the validation service is depending on two other properties on the model.
