Hi,
i'm having some problems(more like i'm just getting confused) while creating
a rule for my project.
I have 2 classes say Phone() and PhoneTC() like below:
Phone()
{
String number;
}
PhoneTC()
{
String tc;
}
also PhoneTC() is inside the Phone() class. like:
Phone()--String number
PhoneTC()--------String tc
now i need to create a rule like this....
when phone numbers are same and the tc values are different for that number
then do something.
will this work??
when
ph1: Phone(number1 : number)
phtc1: PhoneTC(tc1 : tc)
Phone(number == number1) and PhoneTC(tc != tc1)
then
........
can u suggest better rule for the requirement??.... thanks in advance... :)
:) :)

Assuming:-
Phone() {
String number;
PhoneTC phoneTc;
}
PhoneTC() {
String tc;
}
Then something like this should work:-
when
Phone( $n1 : number, $tc : phoneTc.tc )
Phone( number == $n1, phoneTc.tc != $tc )
then

and trying to validate it im getting this errors:

Can you "View source" and paste it?
Also, what version of Guvnor are you using?
Please also include your actual class model - not that I assume to be the
case.
Thanks,

Unfortunately this appears to be a problem with 5.2.
There is an additional space in "phoneTypeCode .tc" which should read
"phoneTypecode.tc".
I have confirmed this does not happen in 5.4.CR1 (and possibly earlier):-
1.|rule "r2"2.| dialect "mvel"3.| when4.| Phone( $ac :
areaCode, $tc : ptc.tc)5.| Phone( areaCode == $ac , ptc.tc != $tc )6.
| then7.|end

If you must use 5.2 you can try using "from" to access the PhoneTypecode,
rather than (I assume) an expression:-
$p : Phone( )
$tc : PhoneTypecode( ... ) from $p.phoneTypeCode
etc.

ok...then you are saying that this code should work on RAD perfectly...sorry
i'm asking so silly questions because i dont have the required files to run
the code at present...so cant check it myself....

Rational Application Developer?
The generated DRL (from using Guvnor 5.2) is flawed, so it won't run
anywhere.
If you write the DRL by hand it should work on 5.2 (I don't believe there
have been any major enhancements since then that would affect what you
want).
If you can use Guvnor 5.4 (the generated DRL will be correct), or use the
"from" construct the DRL should work anywhere too.
I don't know where or how you're trying to run the rules you are now trying
to author so find it difficult to answer any further.
With kind regards,
Mike
