Using Talend built the latest version from source (com.liferay.talend.definition-0.4.0-SNAPSHOT.jar) I am getting an Authorization error and a message that says: Parameter (Authorization Type) is empty but is required

Instructions:
we expect that this is default value and it is always set.

I found resource file:

Try to locate source that reefers to language key Node.parameterEmpty

Either serializator fails to serialize default value if value was not explicitly selected or deserializator fails to do the job or postDeserialize initializeProperties fails.

Based on it we can investigate problem. Same problem relates to (Red exclamation mark) which disappears once component is clicked. But still user is not able to run job in designer until all components with exclamation mark are clicked.
