     [ https://issues.jboss.org/browse/DROOLS-3972?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Almas Toimbekov updated DROOLS-3972:
------------------------------------
    Steps to Reproduce: 

{code:java}
rule "Rule 1"
salience 30
when

then
    Resource resource1 = new Resource();
    resource1.setName("Resource 1");
    resource1.setAmount("5");
    insert(resource1);
    System.out.println("First");
end

rule "Rule 2"
salience 20
//no-loop - next rule fires if use 'update()' instead
when
    $resource1: Resource(name == "Resource 1")
then
    modify($resource1) {setAmount("20")};
//    update($resource1);
    System.out.println("Second");
end

rule "Rule 3"
salience 30
when
    $resource1: Resource(name == "Resource 1", Double.parseDouble(amount) == "20")
//    - interesting that the line below fires this rule
//    $resource1: Resource(name == "Resource 1", amount.startsWith("20"))
then
    System.out.println("Rule is fired"); //doesn't fire
end
{code}

> When I modify amount in an example below from 5 to 20 (both are Strings) and then try to evaluate this fact parsing it to Double - the third rule doesn't fire. But it fires when use 'update()' instead of 'modify() {}'
