-------------------------------------------------------------
I found a solution, if body is set to {{null}} then a top object from stack is taken, if set
to anything else, the body is evaluated, event empty.

> Key: WW-5086
> URL: https://issues.apache.org/jira/browse/WW-5086
> Project: Struts 2
> Issue Type: Bug
> Components: Core Tags
> Affects Versions: 2.5.22
> Reporter: Pierre-Yves Soblet
> Assignee: Lukasz Lenart
> Priority: Major
> Fix For: 2.5.24, 2.6

> Attachments: 20200814_WW-5086.patch, diff-2.5.22_2.5.24-SNAPSHOT.pdf

> In Struts 2.5.22, the following JSP fragment:
> {code:java}
> <s:set var="myVariable"> </s:set>
> <s:property value="#myVariable"/>
> {code}
> generates the following HTML fragment:
> {code:java}
> com.sample.MyAction@c1a47f6c
> {code}
> I would expect an empty output (as {{trimBody}} is set to "true" by default).
>
> Moreover, when the {{set}} tag body is empty:
> {code:java}
> <s:set var="myVariable" trimBody="false"/>
> <s:property value="#myVariable"/>
> {code}
> disregarding the value of the {{trimBody}} attribute, the output is the same:
> {code:java}
> com.sample.MyAction@c1a47f6c
> {code}
