Daniel López created WW-5424:
--------------------------------
Summary: ClassCastException with tag "set" when variable name has
length=1
Key: WW-5424
URL: https://issues.apache.org/jira/browse/WW-5424
Project: Struts 2
Issue Type: Bug
Components: Core Tags
Affects Versions: 6.4.0
Reporter: Daniel López
I think it is caused by the refactor of WW-5333
When the tag "set" is used to define a variable whose name is of length 1, a
java.lang.ClassCastException (class java.lang.Character cannot be cast to class
java.lang.String ) is thrown.
Test case:
{code:java}
// code placeholder
<s:set var="a" value="1" /> a = <s:property value="a"/>
<s:set var="b" value="2" scope="page" /> b = <s:property value="b" />{code}
Expected result:
{code:java}
// code placeholder
a = 1
b = 2{code}
actual result:
{code:java}
a = 1
b ={code}
Both "s:set" throws exception when storing the value in page context. Value of
a is retrieved as it is successfully saved in default context
Exception trace
{code:java}
// code placeholder
Error setting value [2] with expression [#attr['b']]
java.lang.ClassCastException: class java.lang.Character cannot be cast to class
java.lang.String (java.lang.Character and java.lang.String are in module
java.base of loader 'bootstrap')

When name is of length 1, the key is created as Character not String, and it
fails when trying to store in a
AttributeMap extends AbstractMap<String, Object>
