Hi,
I'm trying to implement CHANGESET.xml functinlaity through some example.Here

I can look into the solution of writing my own Java application for this
solution. But I would still like to understand, if the problem is just
because of the 3 values being checked in the rules ? Do complex rules dont
have more than 1 checks ?
If yes then this case should be supported no matter ho
Assuming that the remaining 19998 rules are of the same kind, there is a
lot of data in these rules, and only very little logic. Ignoring the issue

Did you remember to bind $item to some expression in the LHS ? Maybe you just
called that "item" without the $ :)

My rules are as follows.
rule "rule1"
salience -2
dialect "mvel"
when
stud : Student ( field == "ARTS", state.equals("WA"))
then
java.util.List subList = new java.util.ArrayList();
Subject subject = new Subject();
subject.setName("ABC");
subject.setFees(33454);
what is this doing:
for (int i = 0; i < $item.quantity; i++) {
$gsc.doSomethingElse($item.id);
}
"i" is not being used inside the $gsc.doSomethingElse($item.id); sentence..
that means that you are executing that always with the same
parameter.. do you really need that?
By the way
Strangely, after making the changes, that 'for' loop makes the Drools
engine to come up with the same error (no such identifier).
I commented the loop and it does not throw that error.
Any ideas why this happens?
Thanks

you can do
$gsc.doSomething($item.id);
for (int i = 0; i < $item.quantity; i++) {
$gsc.doSomethingElse($item.id);
}
update($gsc);
but by the way.. that loop is not doing anything ..

Hello,
I suppose that means something like:
modify ($gsc) {
doSomething($item.id);
}
for (int i = 0; i < $item.quantity; i++) {
$gsc.doSomethingElse($item.id);
}
update($gsc);

> No can do,
No can do, because within a modify block a comma-separated list of (setter)
method calls of the object between the parentheses must be written.
Note that you can change a fact (without a modify statement) - just follow
this with an update call.
See the Expert manual for details.

You just need to do the loop outside the modify block and then just
update the object.

Hello, guys,
I have the following snippet of a right side rule:
modify ($gsc) {
doSomething($item.id);
for (int i = 0; i < $item.quantity; i++) {
doSomethingElse($item.id);
}
}

Yes, mvel2 is a bundle in my framework and I add this file in META-INF.
I find drools.packagebuilder.conf in droos-compiler, and I copy this to my
META-INF dir.
And it works!! Aleluya

Do you have the mvel2 bundle in your class path?
Did you add the file that I mention inside the META-INF dir inside your app?

If it works we can prove that most of the OSGI containers works in the
same way :)

Looking at the stack trace, if you are on the same version as drools as me it

Thanks for the response Michael. I did get past the error by adding an

I still think, in my opinion, it is worthwhile adding the ability to define
Template Keys in DSL in Guvnor.
A simple (contrived and incomplete example) DSL might be:-
[when] There is an insurance policy quote=$p : PolicyQuote( )
[when] Number of previous claims on policy is between {min} and
{max
Hi Frank,
thanks for your follow-up.
As much as I like source code generators, I must confess that I've come to
dislike the generation of many almost identical chunks, e.g., varying only
in literals.
This means that using templates without an "if" in the available macro
language is a "weak" tool
Guvnor doesn't use OSGi.
The stack trace suggests the JAR you are has a dependency on OSGi:-
org.drools.guvnor.server.contenthandler.ModelContentHandler.getImportsFromJar.
The remainder of the stack trace relates to trying to load the imported
class.
