Emond Papegaaij resolved WICKET-4775.
-------------------------------------
Resolution: Fixed
Fix Version/s: 6.1.0
The merge method now first removes named keys and adds them from 'other'. This
preserves multiple values in 'other'.
While fixing this bug, I've also discovered and fixed a bug in merging index
parameters: if this contains '0' and '1' and other contains '1' and '2', the
value under '0' was overwritten with null.
> PageParameters#mergeWith may loose values of the 'other' PP

> like:
> for (NamedPair curNamed : other.getAllNamed())

> values.With the current code only the last name/value pair is preserved.
