Change bean child values based on parent ? #3728

benprim ·

I'm working on a polymorphic bean and I'd like to change the display based on a user choice made in the parent Bean.
For instance i'm trying to display different information on a repository
So the choice of the repository is in the parent Bean and there's a ChildBeans listing information based on the
chosen repository.
I thought I could use a PropertyChangedListener but it doesn't look like we're going through the setter each time the user change his choice.
Also I'm using ChoiceProvider and the fact that it needs a static method is not helping me...
Am I missing something obvious to do this easily ??

The polymorphic bean allows you to use different implementations for different choices automatically. And different information can put into different implementations. Or am I missing something here?

The thing is I need to get information from the parent class to dynamically construct choices in the child bean.
To give you what i'm trying to achieve :
So the parent bean has a control to select a Perforce repository from the configuration repository list.
Then based on the chosen repository I would like to display the list of users from that repository.
To do this I'm using @ChoiceProvider to build the list of user.
But I have 2 issues :

  • @ChoiceProvider expect a static function
  • When if the user chooses a different repository in the list i'm not notified of the change

You do not need to use custom bean in this case. Just define two variables, one is repository, and another is user, the user choices uses some script like below:
def repoName = vars.getValue("repoName");
// now construct the user list using the repoName.

Also here is a tutorial demonstrating the idea:
