> Key: ISIS-674
> URL: https://issues.apache.org/jira/browse/ISIS-674
> Project: Isis
> Issue Type: New Feature
> Components: Core, Viewer: Wicket
> Affects Versions: viewer-wicket-1.3.1, core-1.3.0
> Reporter: Dan Haywood
> Assignee: Dan Haywood
> Priority: Minor
> Fix For: viewer-wicket-1.5.0, core-1.5.0
>
>
> For example:
> public void foo(
> Charge charge,
> BigDecimal amount,
> String description) {
>
> }
> public String default2Foo(Charge charge, BigDecimal amount) {
> return charge != null && amount != null? amount + " "
> charge.getDescription() : null;
> }
> Here, the value of the 'description' parameter is defaulted from that of both
> the preceding 'charge' and 'amount' parameters. Changing either should cause
> the default value for the 'description' to be recomputed.
> This is analogous to the way that choices are recomputed for
> category/subcategory.
