-----------------------------------------
Summary: Add a MM validation for number of parameters in
supporting methods, eg choices5Act()
Key: ISIS-3331
URL: https://issues.apache.org/jira/browse/ISIS-3331
Project: Isis
Issue Type: Improvement
Affects Versions: 2.0.0-M9
Reporter: Daniel Keir Haywood
Fix For: 2.0.0-RC1
In converting v1 to v2, we came across a supporting "choices" method that was
incorrectly accepted in v1, but rejected in v2 as being orphaned.
```
public Foo myAction(X x, Y y, Z z, W w) \{ ... }
public List<Z> choices2(X x, Y y, Z z, W w) \{ ... }
```
The error was that the choices method incorrectly included parameters AFTER the
'Nth' parameter, in other words it should have been:
```
public List<Z> choices2(X x, Y y) \{ ... }
```
It would be preferable if a MM validation (with higher priority than the one
that triggered) could have given a message something like:
"there should only be 2 parameters in "choices2(...)", instead found 4."
