---------------------------------------
Summary: Introduce read-only interface for PageParameters
Key: WICKET-4774
URL: https://issues.apache.org/jira/browse/WICKET-4774
Project: Wicket
Issue Type: Improvement
Components: wicket
Affects Versions: 6.0.0
Reporter: Martin Grigorov
Cuurently org.apache.wicket.Page#getPageParameters() and
org.apache.wicket.request.resource.IResource.Attributes#getParameters() return
a mutable PageParameters. For the latter this is not a problem since it is not
stored and reused for url generation.
In the case with Page#getPageParameters() this instance is live until the page
instance is alive. Some users make a mistake to modify the parameters (by using
#add, #set, #remove) just to create an Url for some other page and later page's
pageparameters are no more the real ones.
We can improve that by introducing an interface with getter methods only.
