Subject [jira] [Commented] (TAP5-1285) Allow GET method in form component
Date Tue, 09 Aug 2011 18:49:28 GMT

    [ https://issues.apache.org/jira/browse/TAP5-1285?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13081837#comment-13081837
] 

Howard M. Lewis Ship commented on TAP5-1285:
--------------------------------------------

It's quite reasonable to build a form without the Form component.

<form method="get" action="${pageActivationURL}"> ... <input type="text" name="q"
....

Then in your Java code you provide the pageActivationURL, and an activate event handler. 
You can leverage the PageRenderLinkSource service to generate the URL, and the @RequestParameter
 or @ActivationRequestParameter annotations to get the value of the field.

> The Tapestry form component is currently only supporting the "POST" method.
> The POST method is usually associated with changing the "model" on the server side, e.g.
in REST applications, POST indicates that a resource is modified, if I am not mistaken.
> The lack of GET support makes it necessary to use POST also for simple queries, such
as a search field, where the model is not modified.
> This is a) semantically irritating, since for example a search query will not modify
state and
> b) requires extra "work", for example a redirect-after-post, where it should not be necessary.
> Since Tapestry aspires to make the simple things easy, the difficult things possible,
I think it should provide first-class support for the GET method.
