Subject [jira] Commented: (MYFACES-1832) bad charset encoding on <f:param> tag
Date Thu, 07 Aug 2008 00:12:44 GMT


Leonardo Uribe commented on MYFACES-1832:

The problem with this issue is the params are encoded twice:

1 When is first processed on HtmlLinkRendererBase.addChildParameters
2. When is written the onclick attribute using writer.writeAttribute.

 The strange part is what jsf ri api says about the behavior of f:param (on h:commandLink):

"....The name and the value(for UIParam children) must be URLEncoded..."

but on h:outputLink says this:

"....... The name of the UIParameter goes on the left hand side, and the value of the UIParameter
on the right hand side. The name and the value must be URLEncoded....."

But for render parameters for h:outputLink it is used URLEncoder.encode (right), but on h:commandLink
it is not used (why if the api doc says the same). 

The problem about how to solve this issue is if we have to use URLEncoder.encode (as the doc
says) or just do no encoding (but letting writer.writeAttribute encode it).

>                     <h:outputText value="some"/>
>                     <f:param name="id" value="#{}"/>
>                  </h:commandLink>
> </h:form> 
> using <f:param name="id" value="#{}"> tag inside <h:commandLink>
, I see that value has a bad encoding... if I use a word with special characters
as à, è, ù, ì as for example 'modalità' , it is encoded into 'modalit&amp;#224'
instead of 'modalit&agrave' . When I click on link through command link, that id cannot
to be decoded and so cannot to work with the real value
