Dan Haywood created ISIS-674:
--------------------------------
Summary: Allow action parameters to be defaulted based on the
(change of) value of other parameters.
Key: ISIS-674
URL: https://issues.apache.org/jira/browse/ISIS-674
Project: Isis
Issue Type: New Feature
Components: Core, Viewer: Wicket
Affects Versions: core-1.3.0, viewer-wicket-1.3.1
Reporter: Dan Haywood
Assignee: Dan Haywood
Priority: Minor
Fix For: viewer-wicket-1.4.0, core-1.4.0
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.
