Derived Property Field Plugin

Hi guys!

Do you know, if BrXM/Wicket has a property field plugin which will be derived from another property.

For example, I have two fields in document type “First Name” and “Second Name”, and the third filed “Full Name” should be resolved and displayed automatically like First Name filed + Second Name field.

I know that there is a Derived Data capability, but it is triggered after session saving. But I need to see result during editing the document.

I found, how I can perform what i need with Dynamic Dropdown plugin using observer etc. Is there something that I can use for String/Boolean fields?

Thanks in advance!

Maybe you could achieve the same observer/observable functionality by overriding the default string/boolean fields? Just a suggestion. Never tried this myself

Thank you for advice!
