Two ways you can do this:
1. ExListPersons can access EXShowCompany through its 'parent' instance
variable. So ExListPersons can simply check 'parent companyID'.
2. ExShowCompany can use #addHandlers to pass information down to
ExListPersons. For example,
(template elementNamed: 'persons')
onDisplay: [:p | p companyID: companyID]
Does this work for what you need?
