It seems that the initial hyphen merges the DSL definition's right hand side
into the parenthesis of the last preceding term, even if that one is an
eval, which itself is meant to go into some preceding pattern.
You could work around that by making all evals Conditional Elements rather
than Inline
Thx for your answer.
I tried again the rule, removing the extra space after hyphen from DSL
expresion. No luck. So, I tried a few more cases, and the only one that worked
correctly was #3.
It seems to me that is somehow related to the parenthesis, although it might be
something else. Hope this
Hi all,
I am using Drools Guvnor 5.1. I created a rule that uses eval, and OR for
conditions. When I tested the rule, I noticed in the log, that actually the
rule fired twice.
The error seemed to be caused by eval and or combination. When I re-wrote the
rule to not use eval, it fired only once
can you try with this:
[when] There is an Asset=asset:Asset()
[when] -name is empty=eval(StringUtils.isBlank(name))
[when] -tag is empty=eval(StringUtils.isBlank(tag))

Hi all,
I am using the latest Guvnor release (5.1), and I have the following DSL
expression where I use "-" to have conditions on multiple lines:
[when] There is an Asset=asset:Asset()
[when]- name is empty=eval(StringUtils.isBlank(name))
[when]- tag is empty=eval(StringUtils.isBlank(tag))

I have the application setup where the drl is generated from the database and

Any help is much appreciated. Thanks.

The changeset itself dictates what resources to monitor, if I understand it
properly, so if you're just looking for new packages just add them to the

Hey Laird,
How do I configure the resource adaptor to load a specific resource? I have
two changesets I would like it to monitor. Is this handled in the ra.xml? I
couldn't seem to find what it was monitoring. :)

Hi,
Does anyone have a production project that is using drools persistence and has

If anyone is, how do you create your KnowledgeSession(s) and handle starting

So as not to confuse everybody - it seems that the 5.1 textual version of a
dsl now looks like this:
[condition][]There is an element {eVar}={eVar} : Element()
[condition][]- called {nVar}={nVar} : name
[condition][]- other than {oVar}=this != {oVar}
[condition][]- where {eVar} is disjoint from {o
It is possible to hide the eval for computing the intersection in a DSL.
Given
public class Element {
private String name;
private Set numbers;
public Element( String name, Integer... numbers ){ ... }
// getters...
public boolean disjointWith( Element other ){
Set ownN
The problem you are having is because since 5.1, you need to authenticate to
get change-sets or resources from guvnor.
You can put authentication data in the change-set doing something like this:
Unfortunately, basicAuthentication, username and admin properties are not
supported

StatefulSessions are not thread safe.

Hi, there.
I need advice on how to approach the following. Hope I'm being clear:

- The database is being updated every now and then.
- I need to perform a bunch of calculations based on what's on the DB.
