Sunjay,
Methods called by using the "from" CE are expected to return a collection
of VO's, not boolean results. For your case, probably what you want is
something like:
ItemVo( statusCode : itemStatusCode != null, (*
itemValidationDao.isValidItemStatus(statusCode)*) )
A predicate allow you to call a method returning a boolean value and use
it as a constraint.

2007/4/5, Sanjay Singh - s0singh <[EMAIL PROTECTED]>:
Here is a quick test i was trying to do for calling the dao in LHS but it
fails .. what am i missing ..
global com.itemfile.item.dao.ItemValidationDao itemValidationDao;
global com.itemfile.rules.ValidationErrorMap errors;
rule "Item should have a valid status"
when
ItemVo( statusCode : itemStatusCode != null)
*ItemVo( statusCode == true ) from itemValidationDao.isValidItemStatus
(statusCode)*
then
errors.addValidationError("nullItemStatusCode","Item Status Code is
null");
System.out.println("Item Base Defaults Called" +
itemValidationDao.isValidItemStatus(statusCode));
System.out.println("Item Status Code is null");
end
Caused by: org.drools.rule.InvalidRulePackage: unknown:32:28 Unexpected
token 'itemValidationDao'
isValidItemStatus () method returns a boolean and i need to check if
thats true than go to the RHS side .... somehow it does not recognize
itemValidationDao in LHS side .. RHS same call works ...
Can anybody suggest how to call database in LHS ...
thanks
