[jira] [Updated] (JEXL-191) Jexl3 unsolvable property exception
when using enum
[ https://issues.apache.org/jira/browse/JEXL-191?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Constantin Mitocaru updated JEXL-191:
-------------------------------------
Environment: (was: This code used to work under jexl2
{code:java}
public enum Gender { MALE, FEMALE};
public static void main( String[] args ) throws ClassNotFoundException {
JexlEngine jexl = new JexlEngine();
Record r = new Record();
r.setHeader(new RecordHeader());
JexlContext jc = new MapContext();
jc.set("r", r );
jc.set("com.sytrue.objects.Gender", Gender.class );
Expression e = jexl.createExpression( "r.header.gender=com.sytrue.objects.Gender.FEMALE" );
System.out.println( e.evaluate(jc) );
}
{code}
but under jexl3 it throws an exception:
{code:java}
public static void main( String[] args ) throws ClassNotFoundException {
JexlEngine jexl = new JexlBuilder().create();
Record r = new Record();
r.setHeader(new RecordHeader());
JexlContext jc = new MapContext();
jc.set("r", r );
jc.set("com.sytrue.objects.Gender", Gender.class );
JexlExpression e = jexl.createExpression( "r.header.gender=com.sytrue.objects.Gender.FEMALE" );
System.out.println( e.evaluate(jc) );
}
{code}
The exception is:
{code}
Exception in thread "main" org.apache.commons.jexl3.JexlException$Property: com.sytrue.objects.record.app.JexlTestApp.main@1:42 unsolvable property 'FEMALE'
{code}
Temporary workaround is using the valueOf method:
{code:java}
JexlExpression e = jexl.createExpression( "r.header.gender=com.sytrue.objects.Gender.valueOf('FEMALE')" );
{code}
It seems that I no longer can access the enum type in jexl3.
Is there any reason this doesn't work anymore or it is a bug)
