Subject Re: Apache Struts 2.3.35 Upgrade - backward incompatibility in s:if
Date Thu, 30 Aug 2018 08:40:14 GMT
Hi Lukasz,

Thanks for your answer. Yes, it seems related, adding this constant works
around the issue.
Out of curiosity, is the problem the conversion from List to XWorkList
mentioned
by Yasser
<https://issues.apache.org/jira/browse/WW-4954?focusedCommentId=16593382&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16593382>
?

Follow up questions:

1. What is the expected impact of this change? On our previous upgrade from
34 to 35 our risk assessment determined no risk, based on the assumption
that the change was backwards compatible. Since it is not (and we need to
perform the additional change in struts.xml), can you tell us if there is
any area we should worry about when upgrading?

2. Should the logs have shown this? With devMode=true, I see no difference
in the logs from 34 to 35

3. Is it possible to change the release notes to tell about this
incompatibility? Going forward, is there a way to improve the compatibility
assessments?

Kind regards,
Miguel
