I'm creating many Tasks from the AbstractCustomServiceTask with their own properties i want the user to fill. But i'm wondering if we can create some properties that the user CAN T see in the task properties wich contains a default value. For example, i would love to create a property called taskName, type string with a value "toto" inside. But i d'on t want the user to see a field when he will go on the property of his task. Nethertheless, i want to catch it in my java call by a normal procedure with an Expression… Is that possible ? I'm not sure i'm so clear…
