My JAX-RS validator is based on our org.jboss.tools.common.validation.ValidationErrorManager, but it is currently triggered when the user saves a file or during a full build, only.

What I would like to try is to have "as-you-type" validation, so that problem markers can be added/removed without having to wait for the next build, just like JDT does. Is there a way to configure the validator to get this behaviour, or is it a limitation of the WST Validator ?
