Peter Ertl commented on WICKET-3938:
------------------------------------
I think he meant to remove 'value1' from multi-value 'key1' so that
key1='value2' will be left
> Impossible to remove particular key-value from PageParameters

> There is no way to delete particular key-value from page parameters.
> Example:
> PageParameters parameters = new PageParameters("key1=value1,key1=value2");
> //just to demonstrate, but actuall parameters comes from get request
> imposible to remove value1 from parameters.
> Workaround - create new PageParameters with filtering by key and value.
