[rules-users] Timer and AgendaFilter
Hi, I have a rule with a timer and call fireAllRules(AgendaFilter agendaFilter) with an AgendaFilter. I can see the Activation is fired after the delay but accept(Activation activation) in my AgendaFilter isn't invoked. My AgendaFilter is working well for other rules without timers. Is this a bug or wanted that ScheduledActivations aren't passed to the AgendaFilter? I'm using drools expert 5.5.0.Final.

Two clarifications first:
1) Which version are you using?
Version 5.4.0.Final
2) Is TrackerUpdate a static class inside TrackerRemote?
In case, could you post the exact import statements you are using?
It is a normal class inside TrackerRemote.
public class TrackerRemote extends vrpn.VRPNDevice implements
java.lang.Runnable {
public class TrackerUpdate {...
I imported:
import vrpn.TrackerRemote;
and used it as follows:
rule TrackerRemote.TrackerUpdate
when
message:TrackerRemote.TrackerUpdate()
then
System.out.println(Tracker: + message);
end
Extra information:
I have been trying to add type declarations in one file and import them
in another and I get exactly the same error message. There I did this:
package derooms.be.testRule
declare TestEvent
@typesafe(false)
number : int
message : String
end
and then a rule:
package derooms.be.testRule
rule TestEvent
when
event:TestEvent(message == doesDynamicEventTypeWork?)
then
System.out.println(Got Event: + event.data);
end

@Mark: There's really no need to claim additional bugs ;-)
@Jeetendra: Within a pattern (such as ProposalLight(...)) you may
write bindings and constraints, which are boolean expressions. Older
versions had a much more restricted syntax for constraints, and
general (Java-style) expressions were only peremitted by enclosing
them in eval(...). In 5.5.0, as soon as you open a parenthesis, you
have to stick to plain old Java (or MVEL) syntax, and eval is a name
like any other. Recognizing eval(...) as the legacy marker for
introducing an expression has to be kept, but only at the outermost
parenthesis nesting level of constraint expressions. See example #1
below:
### 1 ###
function boolean positive(int a){ return a 0; }
// legacy style constraint, use eval() to wrap boolean expression
$msg: Message( eval(positive($msg.getText().length())) )
// modern style: boolean expression
$msg: Message( positive($msg.getText().length()) )
// modern style: boolean expression with redundant parentheses
$msg: Message( ( positive($msg.getText().length()) ) )
The next example demostrates that eval is a soft keyword, with
recognition restricted to certain places:
### 2 ###
function boolean eval(int a){ return a 0; } // Why not call a
function eval?
// modern style: boolean expression, parentheses required to bypass
soft eval recognition
$msg: Message( ( eval($msg.getText().length()) ) )
So, the answer to your question How can I make it work? is quite
simple: add a declaration of a boolean function eval, like this:
function boolean eval( boolean b ){ return b; }
And, please, do not use terms like throws an exception when a simple
syntax error is reported.

So DRL_1, this works perfectly fine.

DRL_2, this doesn't work. and throws [Error: unable to resolve method

Notice that extra paranthesis around eval(). This is where Drools 5.5
throws exception. Can someone please explain why this extra paranthesis
throws exception and how can I make it work.
Thanks,

The error message suggests that you have made a syntactic error in a
rule which is not the one you have posted, or you have modified the
rule too much to be of any help. Post again, taking great care not to
omit anything or to change the cause of the problem. Also, indicate
precisely the declaration of the function compareDatesWithTime().

Hi,
Snippet of my DRL .

when

then
$obj.addFailedRule(Rev: Start Time 2 Hours in

This fails during compilation and throws error:

[Line: 6, Column: 2] : [Rule name='Proposal - Start time is after

2 hour']
I am using Drools 5.5 and I found the cause that my code runs in
strict
mode.. so If I set strict mode to false then this would work. Now I am
not
sure how to make it to false.
Here's the code I am using:
PackageBuilderConfiguration packageBuilderConfiguration = new
PackageBuilderConfiguration();
PackageBuilder packageBuilder = new
PackageBuilder(packageBuilderConfiguration);
packageBuilder.addPackageFromDrl(drl.getCharacterStream());
Can someone please suggest me how to do that??
