Alan Comeau created WW-4848:
-------------------------------
Summary: The if test can accidently incorrectly assign a new value
to an object
Key: WW-4848
URL: https://issues.apache.org/jira/browse/WW-4848
Project: Struts 2
Issue Type: Bug
Reporter: Alan Comeau
Priority: Minor
The <s:if tag has the side effect of assigning to an existing object
if the comparison is badly formed using = instead of ==
<s:if test="user.id = 0">
//at this point the user.id is now 0 not its original value
</s:if>
even though this is clearly badly formed, the test should not assign anything
to the object
