declaration of 2 variables in the init part of accumulate is not possible
-------------------------------------------------------------------------

                 Key: JBRULES-2058
                 URL: https://jira.jboss.org/jira/browse/JBRULES-2058
             Project: JBoss Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-compiler
    Affects Versions: 5.0.0.CR1
            Reporter: loiez etienne
            Assignee: Mark Proctor


Take a rule with 2 variables int the init part, like
		$maxCa:CompanyCA() from accumulate($ca:CompanyCA($year:year) from $p.cas, 
										init(ecrm.party.CompanyCA currentCA=null;int maxYear = 0;),
										action(maxYear = Math.max(maxYear, $year);),
										result(currentCA)); 
which can return the year and the ca where the ca is max.

It won't compile with the error that company CA is not declare.

The bug is in the class org.drools.rule.builder.dialect.java.JavaAccumulateBuilder
line 194
            int index = 0;
            for ( Iterator it = initCodeAnalysis.getLocalVariablesMap().entrySet().iterator(); it.hasNext(); ) {
                Map.Entry entry = (Map.Entry) it.next();
                attributes[index] = (String) entry.getKey();
                attributesTypes[index] = ((JavaLocalDeclarationDescr) entry.getValue()).getType();
            }
when the variables are put in the context, only the first is put (index stay at 0)

We should increment the index
            int index = 0;
            for ( Iterator it = initCodeAnalysis.getLocalVariablesMap().entrySet().iterator(); it.hasNext(); ) {
                Map.Entry entry = (Map.Entry) it.next();
                attributes[index] = (String) entry.getKey();
                attributesTypes[index] = ((JavaLocalDeclarationDescr) entry.getValue()).getType();
                index ++;
            }
