> Key: WICKET-3406
> URL: https://issues.apache.org/jira/browse/WICKET-3406
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.5-RC1
> Reporter: todd wolff
> Assignee: Igor Vaynberg
>
> ServletWebRequest reads the post parameters from entity body rather than
> using getParameterMap and/or getParamteterNames method as indicated by
> ServletAPI:
> "If the parameter data was sent in the request body, such as occurs with an
> HTTP POST request, then reading the body directly via getInputStream() or
> getReader() can interfere with the execution of this method."
> IMO, trying to distinguish the get (query) parameters from the post
> parameters in the new Wicket request API is problematic. The servlet API
> does not differentiate in terms of the parameter's source and programmers are
> therefore not inclined to handle them differently. Within Wicket 1.4..x, the
> PageParameters object passed to a page's constructor contained parameters
> from both sources, now it no longer does, which will require that the user
> handle posted parameters separately - which is confusing.
