Problem with Biz Rule Signature

[Veronka]

Hi,

I created a simple Biz Rule on Account Enity which returns a bool.

public static partial class AccountBusinessRules

{

public static bool HasFaxOptOutChangedStep(IAccount account)

{

// TODO: Complete business rule implementation

 bool result = false;

IChangedState state = account as IChangedState;

if (state != null)

{

PropertyChange change = state.GetChangedState().FindPropertyChange("FaxOptOut");

if (change != null) result =

true;

else

result = false;

}

return result;

}

}

----------------------- When using it -------------------- 

if(account.HasFaxOptOutChanged() == true)

     ....

Signature of this biz rule shows Void, even if I defined as bool.

I get the following error: Operator '==' cannot be applied to operands of type 'void' and 'bool'

Any ideas how to fix this?

As far as I know the rules are always void.

What you do is:

public static void HasFaxOpen(IAccount, account, out Bool result)

This should work.

I tried this as well, but when invoking it, function does not takes any parameters Signature still says void HasFaxOptOut() so how do I get the out value?

[apfingstl · Accepted solution]

So What I am doing to create a boolean rule is:

Add a business rule.

As the return type I select Boolean.

Then the method's signature changes to

public static void myrule(IAccount account, out Boolean result)

This is what happens in my system.

Does this make sense?

Yes. I figure ot out yesterday. I did not pick the return type Boolean, I just changed manually the signature.  Beginers mistake... I would havee if the compiler couth this.

Thanks !
