Thanks for you reply Clement,
So, the following should work (in principal)?
* @Property(name = "myProperty" mandatory = true)*
* public void setMyPropertey(String theProperty) {*
* // Calculate new filter based on myProperty*
* String filter = ....*
*
*
* // How do I get an instance of "DependencyModel"?*
* DependencyModel.setFilter(filter);*
* }*
I've never used the DependencyModel class before. How do I gain access to
the correct instance? What maven artifact do I need for this?
