Hi Angel,

Thanks alot, will have a look. In the meantime I hacked the following - quick and dirty to test

created two dummy, hidden properties, these properties are not shown on the form and populated by a script
created a JS file which does the checks and does the date calculation
based on the result, the scripts sets one of the property to 1 and the other to null
created a simple evaluator based on the PropertyNotNull standard one
displaying the indicator based on the result of the evaluators

the solution is not elegant but it allows us to test how it works. Plus, just checked how to set up Eclipse to work with Alfresco, looked so complicated to a non developer, that I decided to hack something as proof of concept
