Links should be able to restrict parameter binding for Ajax requests
--------------------------------------------------------------------
Key: CLK-685
URL: https://issues.apache.org/jira/browse/CLK-685
Project: Click
Issue Type: Sub-task
Components: core
Affects Versions: 2.2.0
Reporter: Bob Schellink
Assignee: Bob Schellink
Fix For: 2.3.0-M1
AbstractLink binds all incoming request parameters to its own parameter map.
This makes the link quite easy to use but has the potential to leak parameters
which isn't targeted at the link.
The problem becomes obvious when using Ajax to invoke a link. Any extra
parameters passed for the Ajax request will be added to the link parameter map.
We need to introduce a "strict" parameter binding strategy for links so that
only those parameters that was defined *before* the processing event should be
bound. The "strict" policy can be set to "on" for Ajax and "off" for normal
requests.
