Re: [Tobago] Problem using tc:tree and request parameters

[Udo Schnurpfeil <ud...@schnurpfeil.de>]

  Hi Alf,

I think the request parameters are working like expected.
Only in the case of "reload" it will depend, if you make a "reload" of 
the "get" or the reload of a later "post" request.
A reload of a "post" will normally reposted after the browser has asked 
the user (may depends on browser and configuration).

For solving the problem, I want to understand why you use the "get" 
request with the non-jsf parameter (see the last section from my last 
mail).

Regards,

Udo
