[jira] [Commented] (WW-5238) Strict Method Invocation (SMI) too strict?

["Lukasz Lenart (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WW-5238?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17611833#comment-17611833 ] 

Lukasz Lenart commented on WW-5238:
-----------------------------------

{{<s:submit action="..."/>}} won't change where the {{<form/>}} is submitted, it's impossible because browser will submit the {{<form />}} always to where the {{action}} attribute points it. The case with {{<s:submit action="..."/>}} will also submit a value {{action:cancel}} and based on that the mapper will decide to use a different action then.

So because of that the action defined with {{<s:submit />}} must be in the same {{namespace}}, if you want to use a different {{namespace}} then you must enable {{struts.mapper.action.prefix.crossNamespaces}} and probably {{struts.enable.SlashesInActionNames}}.

> Got the following error (Error No. 2) when trying to create one record. The prompt method is not supposed to be invoked for aSbmt1. Before that, the aSbmt1 was not accepted (Error No. 1). I tried several ways to try to overwrite the regular expression without success. Was something strange introduced into the Struts 2 version 6.0.3? Is Strict Method Invocation (SMI) in a dead loop? I am surprised at that there is no issue reported for the Struts 2 version 6.0.3 yet.
