[jboss-jira] [JBoss JIRA] (DROOLS-4916) Investigate modify parsing bug in executable model

[Toshiya Kobayashi (Jira)]

    [ https://issues.redhat.com/browse/DROOLS-4916?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14013185#comment-14013185 ] 

Toshiya Kobayashi commented on DROOLS-4916:
-------------------------------------------

Small correction: We should not have "$a" in the modify block because it fails with standard-drl.
{noformat}
modify ($a) {
   getCategories().add("hello");
}
{noformat}
Anyway, I can reproduce the issue with the above rule.

> Then I had a modify statement scattered about:
> {noformat}
> modify ($a) {
>    $a.getCategories().add("hello");
> }
> {noformat}
> The ExecutableModel did not seem to like any of those.  I changed it to:
> {noformat}
> $a.getCategories().add("hello");
> update($a);
> {noformat}
