NodeTypes properties validation feedback kicks in only after properites are populated

[DrNik]

Hi Guys,
as mentioned on this post: https://discuss.neos.io/t/neos-react-ui-nodetype-property-validation-issue/3097 there seems to be a bug in Noes React UI property validation mechanism.
Basically validation feedback kicks in only if the properties that needs to be validated are populated (fill in + apply) first.

Steps to reproduce:

1. Have a NodeType with a property that must be validated, like:

properties:
  [PROPERTY_NAME]:
     [...]
     validation:
        'Neos.Neos/Validation/NotEmptyValidator': []

2. Apply values to properties leaving the must-be-validated property blank -> modifications get applied without warnings or “failed validation” feedback

3. Fill in mandatory property and Apply

4. Empty out the must-be-validated property -> the “validation failed” popup is shown correctly

Tested versions:
Neos: 3.3.4
Neos.UI: 1.0.7

Thanks,
Nicola

Is this still a problem? We worked on validation stuff at the Hamburg Codesprint and with regular fields like the title or url segment it is working fine. Also the create dialog handles this validations.
