Subject [jira] Commented: (IMPERIUS-18) Failure to find the proper method of the anchor object during policy execution
Date Wed, 17 Sep 2008 18:01:46 GMT

    [ https://issues.apache.org/jira/browse/IMPERIUS-18?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12631862#action_12631862

Reza Asadollahi commented on IMPERIUS-18:
-----------------------------------------

Hey Neeraj,
Thanks for applying the patch.
Regarding the change in AnchorMethodInvokeAction.execute method signature to throw SPLException,
I actually changed the ActionBlock.execute method signature and all classes that implement
it. Is it ok if I create one patch file for all files changed? Or you'd like to have one patch
file for each individual file.

Thanks,

> An anchor object has a method named foo with the following signature:
>      public void foo(Object o)
> if this method is used in a SPL policy as foo("test"), the policy will fail to execute
with the following exception since it looks for method foo(java.lang.String) and can not find
it.
