Hi Wolfgang,
Sure. Please find attached a small Maven/Eclipse project containing 3
DRT and 3 unit test cases (Java in src/test/java/org/drools/bug, rules
in src/test/resource/org/drools/bug) :
* Test1OK(.java/.drt/.csv) is the one working well
* Test1KO(.java/.drt/.csv) is the one illustrating the 1) behavior
* Test1KO2(.java/.drt/.csv) is the one illustrating the 2) behavior
Regards,
Bruno.

Before you work on a JIRA could you please provide an (abbreviated)
example of a template that causes both errors?

Hi all,
I am writing rules using Drools Templates and I noticed strange
problems (ocurring when I slightly modify a DRT that works well):
1. the template instanciation depends on the declarations order
of the parameters in the template header
2. if the rule template does not contain a package declaration
(default package) the instanciation of the template fails
I am working with Drools 5.1.1 but those problems occur in
5.2.0.Final and in 5.3.0.Final as well.
Do you think it is worth posting a JIRA?
Anyway let me tell you that Drools Templates are great! Our users
like that feature a lot! They start writing a rule in DRL format
and, once it works, they transform it into a DRT and put data into
a tsv file. It is quite a natural way of working. The general
perception here is that it is easier to "templatize" an existing
DRL than to write a decision table from scratch.
Best regards,
Bruno.
PS:
_DRT that works well_:
template header
*name
message
package templates;
*
import org.drools.bug.Entity;
template "TestTemplate"
rule "Test1 @{row.rowNumber}"
dialect "mvel"
when
Entity( $name : name == "@{name}" )
then
System.out.println("@{message}" + $name);
insert($name);
end
end template
_DRT that does not work_ (first case):
template header
*message
name
package templates;
*
import org.drools.bug.Entity;
template "TestTemplate"
rule "Test1 @{row.rowNumber}"
dialect "mvel"
when
Entity( $name : name == "@{name}" )
then
System.out.println("@{message}" + $name);
insert($name);
end
end template
_DRT that does not work_ (second case):
template header
*name
message
*
import org.drools.bug.Entity;
template "TestTemplate"
rule "Test1 @{row.rowNumber}"
dialect "mvel"
when
Entity( $name : name == "@{name}" )
then
System.out.println("@{message}" + $name);
insert($name);
end
end template
