Re: Is there any way to render the "get" method of form?

[Peter Stavrinides <P....@albourne.com>]

Point us to the Jira Lutz, the HTML 2 specification details the following:
"If the processing of a form is idempotent (i.e. it has no lasting observable effect on the state of the world), then the form method should be GET. Many database searches have no visible side-effects and make ideal applications of query forms."

and:

"If the service associated with the processing of a form has side effects (for example, modification of a database or subscription to a service), the method should be POST."

so I believe you have a case.

Cheers,
Peter

Dear Thiago,

thanks for your patient reply and the advice. Of course I realize that
I can still implement a search with Tapestry, with redirect-after-post
or else, and I have actually done so in the past.

But please take a minute and think about these two things:

1. You say,
> GET was always meant to be used in request that don't change the state of
> the application (including database)

and this is exactly what I would like to use it for - as I said, a
search. You could re-phrase your argument:
"POST was meant for requests that do change the state."
So why do I have to use it for requests that do not?

2. Of course, a lot of things are doable, change the DOM and what not.
But wasn't the idea of Tapestry "make the simple things easy, the
difficult things possible"?
A form with method=get is totally valid HTML, and I think it should be
easy, not complicated.

These two reasons are why I said the lack of get-forms is "puzzling"
me, it just seems somewhat inconsistent with the rest of Tapestry
(which I use and will continue to use with great pleasure).

I did as you told me and created a JIRA ticket (a "wish") for it:
"https://issues.apache.org/jira/browse/TAP5-1285"

Keep up the good work,

Lutz
