Lukasz Lenart updated WW-3193:
------------------------------
Fix Version/s: (was: 2.2.x)
3.x
> Form action always inherits parent extension
> --------------------------------------------
>
> Key: WW-3193
> URL: https://issues.apache.org/jira/browse/WW-3193
> Project: Struts 2
> Issue Type: Improvement
> Affects Versions: 2.1.8
> Reporter: Jasper Rosenberg
> Priority: Minor
> Fix For: 3.x
>
> Attachments: WW-3193.patch

> Here is the basic issue. I have an url that has no extension, eg.
> /Overview-Mustang-c1234
> On that page, I have a form tag that I want to have submit to action
> "changeCar.action", and so the "action" attribute is set to "changeCar".
> This used to work. However, task
> https://issues.apache.org/struts/browse/WW-2267 changed the behavior so that
> the form's action gets the parent mapping's extension
> [DefaultActionMapper.getUriFromActionMapping() called from
> ServletUrlRenderer.renderFormUrl()], in this case the empty string, so the
> generated action ends up as just "changeCar" rather than "changeCar.action"
> Because we have some special handling for our mappings, this url ends up as a
> 404. It just doesn't seem desirable in general however that the same form
> included on different pages with different extensions will generate posts to
> two differently named urls.
> I understand the concept behind this change, but I wonder if it would be
> safer to revert it, and instead add support for an attribute on the form
> which is "extension" which if present overrides the default, but otherwise
> the default is used. Alternatively, it could be an mutli-value such as
> "inherit" (new behavior), "default" (old behavior), or ".ext" (a specific
> extension). With the default value being "default" so as to maintain
> backwards compatibility to the 2.0 branch.
