[rules-users] Guvnor does not like my rule?
Noob alert, first post.
I have a rule that works fine when I run it in a JUnit test. I've imported it
into Guvnor (along with all my referenced pojos and functions) and it will not
build there. Here is the error:
Unable to Analyse Expression for (String curr : (ListString) $validList) {
ValidValue aValidVal = new ValidValue(curr); drools.insert(aValidVal); }; for
(int i=0; i$validList.size(); i++) { String curr = (String)$validList.get(i);
ValidValue aValidVal = new ValidValue(curr); drools.insert(aValidVal); };:
[Error: unexpected token: $validList] [Near : {... rr : (ListString)
$validList) { }] ^ [Line: 1, Column: 35]
What the rules is trying to do is run values from a set of records through a
validation function and then add each of the valid values as individual facts.
Guvnor apparently doesn't like the way the iteration of the list is being done.
I've tried a few different ways of iteration. Thanks in advance for any
advice.
Here is the rule:
when
$validList : List()
from accumulate(
InRecord($value :
value != ),
ListValid($value))
then
for (String curr : (ListString) $validList) {
ValidValue aValidVal = new
ValidValue(curr);
insert(aValidVal);
}
for (int i=0; i$validList.size(); i++) {
String curr =
(String)$validList.get(i);
ValidValue aValidVal = new
ValidValue(curr);
insert(aValidVal);
}

John Perrin

Re: [rules-users] Guvnor does not like my rule?
Thanks folks. I did end up finding something that works. I guess
Guvnor5.2.0.Final still has some quirks. Even this has to be written just
so for the package to build. Everything has to be cast, using typing didn't
seem to work.
when
$validList : List()
from accumulate(
InRecord($value : value != ),
ListValid($value))
then
java.util.Iterator iter =
(java.util.Iterator)$validList.iterator();
while (iter.hasNext()) {
String curr = (String)iter.next();
ValidValue aValidVal = new ValidValue(curr);
insert(aValidVal);
}

Re: [rules-users] Guvnor does not like my rule?
Did you add java.util.Iterator to the packages import section in Guvnor?
