==> Enumeration:
~~~
'SimpleFact.factOne' : ['one','two','three']
~~~
==> Fact: SimpleFact
~~~
public class SimpleFact implements java.io.Serializable
{
static final long serialVersionUID = 1L;
@org.kie.api.definition.type.Label(value = "factOne")
private java.util.List<java.lang.String> factOne;
public SimpleFact()
{
}
public java.util.List<java.lang.String> getFactOne()
{
return this.factOne;
}
public void setFactOne(java.util.List<java.lang.String> factOne)
{
this.factOne = factOne;
}
public SimpleFact(java.util.List<java.lang.String> factOne)
{ this.factOne = factOne; }
}
~~~
==> Guided Rule (using above enumeration and fact):
~~~
package simplepackage;
import java.lang.Number;
rule "SimpleEnumGuidedRule"
dialect "mvel"
when
SimpleFact( factOne contains two )
then
end
~~~
Here you can see that although it is an enumeration for "factOne" , but the chosen value "two" does not contain quotes. This causes the issue given below.
Result while building project/validating the rule:
~~~

Here you can see that although in condition section the values for enumerated field "factOne" is chosen with quotes ("three") , but in then section the setter method does not contain the value in quotes .

==> Guided Decision Template (source given below):
Unfortunately due to some issues , I am not able to see the rule source at my end. But I used the same enumeration as shown above and I can see that it does not cause any validation error. I also tested in a separate project as seen in the attached second archive "Model_TestProject.zip" , where I used similar tests on Guided Decision Template, and there as well the template validates fine and the project builds fine too. However as per some users, they are seeing validation errors in Guided Decision Template too.
RHDM-25 Use of "contains" operator does not add values from enumeration with quotes in Guided Rules etc.
