[jboss-jira] [Red Hat JIRA] (DROOLS-5958) Order of statements described in rule action part does not keep after model generation in executable model.

Order of statements described in rule action part does not keep after model generation in executable model. ----------------------------------------------------------------------------------------------------------- Key: DROOLS-5958 URL: https://issues.redhat.com/browse/DROOLS-5958 Project: Drools Issue Type: Bug Components: executable model Reporter: Luca Molteni Assignee: Luca Molteni Priority: Major Labels: support Attachments: reproducer_model_compiler_14a.zip Building a rule written in MVEL dialect like (*1) in executable rule model, the order of the statements described in action ({{then}}) part of the rule changes after model generation like (\*2). The generated code looks like that all statements outside the {{modify}} blocks come first, followed by all statements inside the {{modify}} blocks, and finally {{update}} statements for the modified properties are called together. The original order of the statements in action part should keep after model generation. (\*1) {noformat} package com.example.reproducer dialect "mvel" rule "rule14a" when $manufacturer : Manufacturer() $model : Model( manufacturer == $manufacturer ) $car : Car( model == $model ) then System.out.println("***** Action of rule14a"); modify($model) { count = $model.count + 1 } System.out.println("$model = " + $model + ", count = " + $model.count); modify($manufacturer) { totalCount = $manufacturer.totalCount + 1 } System.out.println("$manufacturer = " + $manufacturer + ", totalCount = " + $manufacturer.totalCount); end {noformat} (\*2) {{LambdaConsequence<_hash_>.java}} generated from the action ({{then}}) part of the rule. {noformat} @Override() public void execute(org.drools.model.Drools drools, com.example.reproducer.Model $model, com.example.reproducer.Manufacturer $manufacturer) throws java.lang.Exception { System.out.println("***** Action of rule14a"); System.out.println("$model = " + $model + ", count = " + $model.getCount()); System.out.println("$manufacturer = " + $manufacturer + ", totalCount = " + $manufacturer.getTotalCount()); $model.setCount($model.getCount() + 1); $manufacturer.setTotalCount($manufacturer.getTotalCount() + 1); drools.update($model, mask_$model); drools.update($manufacturer, mask_$manufacturer); } {noformat}
