[jboss-jira] [JBoss JIRA] (DROOLS-5214) Executable model compilation fails with constraints containing static method calls

[Mario Fusco (Jira)]

    [ https://issues.redhat.com/browse/DROOLS-5214?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14020305#comment-14020305 ] 

Mario Fusco commented on DROOLS-5214:
-------------------------------------

I reproduced the problem thanks a lot. As a side note I noticed that it happens only if you use the fully qualified name of the class on which you're calling the static method. As a temporary workaround (if necessary) you could import java.util.Arrays and use the simple name in the method invocation like in

{code}
    import java.util.Arrays;
    rule "Array asList"
    when Pojo(Arrays.asList(1,5,2,3).containsAll(integerList))
    then
    end
{code}

> Executable model rule compilation fails on patterns containing Java static method calls as constraints
> Example of DRL that fails to compile:
> {noformat}
>     rule "Array asList"
>     when Pojo(java.util.Arrays.asList(1,5,2,3).containsAll(integerList))
>     then
>     end
> {noformat}
> or
> {noformat}
>     rule "collections disjoint"
>     when $p : Pojo($boundList : integerList)     Pojo(id > $p.id, !java.util.Collections.disjoint( integerList , $boundList ))
>     then
>     end
> {noformat}
> or
> {noformat}
>     rule "containsAll"
>     when Pojo(integerList.containsAll(java.util.Arrays.asList(1,3)), integerList.size() == 2)
>     then
>     end
> {noformat}
> All above examples work fine when compiling without executable model.
