Daniel Wu commented on WW-5238:
-------------------------------
FYI. The fix for WW-5190 seems to be causing the problem. The
DefaultActionMapper now gets the method attached to the action, but in our
case, it is using the action where the form was originally submitted, not the
action that the submit button is pointing to. When the final ActionMapping is
created, it is made up of the submit button action, but has the form action's
method, which doesn't exist.
> Strict Method Invocation (SMI) too strict?

> Key: WW-5238
> URL: https://issues.apache.org/jira/browse/WW-5238
> Project: Struts 2
> Issue Type: Bug
> Components: Core
> Affects Versions: 6.0.3
> Reporter: Daniel Wu
> Priority: Critical
>
> 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.
