Evaluation of EL-Expression fails with custom PropertyResolver
--------------------------------------------------------------
Key: MYFACES-1750
URL: https://issues.apache.org/jira/browse/MYFACES-1750
Project: MyFaces Core
Issue Type: Bug
Components: General
Affects Versions: 1.1.5, 1.1.4, 1.1.3, 1.1.2, 1.1.1
Reporter: Stefan Rinke
When using a custom PropertyResolver in faces-config.xml like this:
<application>
<property-resolver>
org.springframework.web.jsf.MessageSourcePropertyResolver
</property-resolver>
</application>
the evaluation of an expression involving the PropertyResolver fails, when the
expression appears on the right hand side. E.g. the expression #{ bundle.test
== 'xx' } succeeds, whereas #{ 'xx' == bundle.test } fails. In this example the
property resolver is responsible for evaluating the 'test' property on the
object 'bundle'.
MyFaces has an expression factory which reassembles the expressions generated
from the commons-el parser. This is done by replacing the so called 'suffixes'
see org.apache.myfaces.el.ELParserHelper. The bug occurs when instances of
BinaryOperatorExpression are handled, because myfaces only replaces the suffix
of the first operand. This is why the first example works and the second fails.
