[DMN engine] Java Object in DMNContext not working properly with Filter function. --------------------------------------------------------------------------------- Key: DROOLS-2286 URL: https://issues.jboss.org/browse/DROOLS-2286 Project: Drools Issue Type: Bug Components: dmn engine Affects Versions: 7.4.1.Final, 7.5.0.Final Reporter: Thomas Mantegazzi Assignee: Matteo Mortari Attachments: FilterJohns.dmn, FilterOnObjectListBug.java When trying to evaluate a FEEL expression like: {code:java} personList[name = "John"] {code} by inserting into the _DMNContext_ a _Java Object_, the _DMN engine_ doesn't seem to be able to fetch the _name_ field from the object. This doesn't happen if instead of _Java Objects_ we insert a Map. While trying to debug, it seems that the problem is happening in the following method of _FilterExpressionNode_. {code:java} private void evaluateExpressionInContext(EvaluationContext ctx, List results, Object v) { try { ctx.enterFrame(); // handle it as a predicate ctx.setValue( "item", v ); // if it is a Map, need to add all string keys as variables in the context if( v instanceof Map ) { Set<Map.Entry> set = ((Map) v).entrySet(); for( Map.Entry ce : set ) { if( ce.getKey() instanceof String ) { ctx.setValue( (String) ce.getKey(), ce.getValue() ); } } } Object r = this.filter.evaluate( ctx ); if( r instanceof Boolean && ((Boolean)r) == Boolean.TRUE ) { results.add( v ); } } finally { ctx.exitFrame(); } } {code} Also attatched java and DMN test files that showcases the issue.
