Christoph Lenggenhager created WW-4651:
------------------------------------------
Summary: Negative number is considered an arithmetic expression
Key: WW-4651
URL: https://issues.apache.org/jira/browse/WW-4651
Project: Struts 2
Issue Type: Bug
Affects Versions: 2.3.29
Reporter: Christoph Lenggenhager
With the arithmetic expression check that has been introduced with 2.3.29,
negative numbers are considered to be arithmetic expressions.
This makes it impossible to use number fields with negative values as
KeyProperty in collection type conversion.
I can understand that one does not want to have arithmetic expressions in
parameter names. OTOH, I would not consider a negative number as an arithmetic
expression.
Please let me know if I should rather open this issue in the ognl project.
