<div>There seem to be a couple of misunderstandings of what in inferred type is.</div><div><br></div><div>Firstly, it's a fact type just like any other fact. You are inserting it into working memory in your rule. Therefore you need to declare it. I tend to use declared types for inferred facts. i.e.:</div>
<div><br></div><div>declare IsBadDebtor</div><div><span style="white-space:pre-wrap"> </span>debtor: com.invoicestore.domain.Debtor</div><div>end</div><div><br></div><div>Secondly, it does not need to extend anything. Obviously, you could create an IsBadDebtor class, which extends the Debtor class, but that's not required. Note in the above example that debtor is a property of the IsBadDebtor declared type.</div>

That seems odd to me because IsBadDebtor is an inferred object and should have the class Debtor. When you have to declare a class for every type of inferred object you are using that would be strange. These classes would extend the class where they are inferred from and would be totally empty: no own attributes, nor methods. They would only be declared to solve this compilation issue.</div>

<br>
In the Drools documentation is "the buss pass" example of how to use<br>
inference.<br>
<br>
rule "Infer Adult"<br>
when<br>
$p : Person( age >= 18 )<br>
then<br>
insert( new IsAdult( $p ) )<br>
end<br>
<br>
However, when I try this myself I get compilation errors on IsAdult and a<br>
missing ";" after the insert statement. (I am using the Drools plugin in<br>
Eclipse)<br>
<br>
Here is an example of my own what has the same issue:<br>
<br>
//list any import classes here.<br>
import com.example.vdc.VdcLandingPage;<br>
import com.invoicestore.domain.Debtor;<br>
<br>
//declare any global variables here<br>
global VdcLandingPage UI;<br>
<br>
<br>
rule "Infer bad debtor"<br>
<br>
when<br>
$debtor : Debtor( isBadDebtor() == true )<br>
then<br>
insert( new IsBadDebtor( $debtor ) );<br>
end<br>
<br>
<br>
BuildError: Unable to Analyse Expression drools.insert( new IsBadDebtor(<br>
$debtor ) );:<br>
[Error: Failed to compileShared: 1 compilation error(s):<br>
- (1,16) could not resolve class: IsBadDebtor]<br>
[Near : {... drools.insert( new IsBadDebtor( $debtor ) ); ....}]<br>
^<br>
[Line: 23, Column: 0]<br>
<br>
I have studied the Drools documentation and cannot find anything what might<br>
lead to a solution. I have tried to set the dialect to "mvel" but that is<br>
not solving the problem.<br>
<br>
Any suggestions how to solve this?<br>
<br>
<br>
<br>
