Henri Biestro updated JEXL-130:
-------------------------------
Affects Version/s: 2.1.1
Confirmed as bug; fix to come in JexlArithmetic.toBoolean() // non null values
that can not be interpreted as boolean should return true
> Ternary Conditional fails for Object values
> -------------------------------------------
>
> Key: JEXL-130
> URL: https://issues.apache.org/jira/browse/JEXL-130
> Project: Commons JEXL
> Issue Type: Bug
> Affects Versions: 2.1, 2.1.1
> Reporter: William Bakker
> Assignee: Henri Biestro
>
> The documentation states on
> http://commons.apache.org/jexl/reference/syntax.html#Operators :
> {quote}
> The usual ternary conditional operator condition ? if_true : if_false
> operator can be used as well as the
> abbreviation value ?: if_false which returns the value if its evaluation is
> defined, non-null and non-false
> {quote}
> For object values however, it seems that this definition no longer holds in
> 2.1 and higher.
> The following unittests run successfully in 2.0.1, but the test
> "ternaryConditional_mapContainsObject_shouldReturnObject" fails in 2.1 and
> 2.1.1.
> {code}
> import org.apache.commons.jexl2.*;
> import org.junit.*;
> public class JexlTernaryConditionalTest
> {
> @Test
> public void ternaryConditional_mapContainsString_shouldReturnString()
> {
> String myName = "Test.Name";
> Object myValue = "Test.Value";
> JexlEngine myJexlEngine = new JexlEngine();
> MapContext myMapContext = new MapContext();
> myMapContext.set(myName, myValue);
> Object myObjectWithTernaryConditional =
> myJexlEngine.createScript(myName + "?:null").execute(myMapContext);
> Assert.assertEquals(myValue, myObjectWithTernaryConditional);
> }
> @Test
> public void ternaryConditional_mapContainsObject_shouldReturnObject()
> {
> String myName = "Test.Name";
> Object myValue = new Object();
> JexlEngine myJexlEngine = new JexlEngine();
> MapContext myMapContext = new MapContext();
> myMapContext.set(myName, myValue);
> Object myObjectWithTernaryConditional =
> myJexlEngine.createScript(myName + "?:null").execute(myMapContext);
> Assert.assertEquals(myValue, myObjectWithTernaryConditional);
> }
> }
> {code}
