A kind of a Variable Repository

Question

For example, i have a resource called AD, so when i want to access a field of AD i have to do this: accounts[AD].fieldName. But what happens if i change the name of the resource? I have to change all references.
I want to create a kind of a Variable Repository, so for example if i want to access the AD resource i do something like this: accounts[VariableRepository.AD].fieldName.
There is a way to do it?

Yes you can, but unfortunately this isn't as simple as one might expect, because accounts[$(resourceName)].fieldName is not resolved.
However, you can access objects in a list via the get expression:
<set name='resourceName'>
  <s>AD</s>
</set>
<set name='AD'>
  <get>
    <ref>accounts</ref>
    <ref>resourceName</ref>
  </get>
</set>
<set name='AD.fieldName'>
  <s>set the value here</s>
</set>This way, you can retrieve objects by their name from a list. In my example, resourceName is set to a fixed String. What you can do is creating a simple rule that will return the name of the resource, either hard-coding the name there or the rule could even read the name from the repository.
