Merge branch 'ISIS-2001'

> ---------------------------------------------------------------------------------------
>
> Key: ISIS-2001
> URL: https://issues.apache.org/jira/browse/ISIS-2001
> Project: Isis
> Issue Type: New Feature
> Affects Versions: 1.16.2
> Reporter: Dan Haywood
> Assignee: Dan Haywood
> Priority: Major
> Fix For: 1.18.0
>
>
> some notes:
> ActionParametersForm.java
> ScalarPanelAbstract2#updateIfNecessary(..) as a new hook method to be
> implemented everywhere
> - if choices facet then update choices ... DONE ALREADY
> - if default facet then recompute ... TO DO EVERYWHERE, on the getModel()
> - and "sync" the value into the UI widget
> 1. for the existing logic that evaluates choicesX based on choices(Y<x),
> should also evaluate any defaultX that we see.
> 2. also do this for an autoCompleteX
> 3. new logic looking for a change in any scalar, then search for other params
> with a default that depend on that.
> Nice to have, but will need changes to metamodel so we'll leave for now:
> 4. support the idea of disableX for params
> 5. support the idea of hideX for params
> based on a change (autoComplete, choices or scalar)
> ... re-evaluate choices, default, disable, hide
> ~~~~~~~~~~
> Organisation -> BankAccount
> public void doSomething(
> Organisation org,
> BankAccount bankAccount,
> ...
> ) {

> public List<Organisation> autoComplete0DoSomething(String str) { .... }
> public List<Organisation> choices0DoSomething() { .... }
> public List<BankAccount> choices1DoSomething(Organisation org) { ... }
> public BankAccount default1DoSomething(Organisation org) { /*return
> choices1DoSomething(organisation).get(0); */ }
> ~~~~~~~~~~
> public void calc(
> BigDecimal netAmount,
> BigDecimal vatAmount,
> BigDecimal grossAmount
> ...

> public BigDecimal default2Calc(BigDecimal netAmount, BigDecimal vatAmount) {
> return netAmount + vatAmount; }
> //public String disable2Calc() { return "disabled"; }
> //public boolean hide2Calc(BigDecimal netAmount, BigDecimal vatAmount) {
> return netAmount == null; }
