Good morning,
I want to use two sources (with restrictions) in one rule but show it's wrong, when I put the two sources without restrictions the eclipse does not show errors.

rule MethodDeclarationToMethodUnit
{
from
source: KDM!MethodUnit (source.kind = #constructor)
,parametros: KDM!ParameterUnit

The filter must be at the end of all the "sources".
By the way, be careful that - as such - this rule will be activated for every possible couple of (MethodUnit,ParameterUnit) in your model, I don't think that is what you want to achieve here (so you probably have to add another condition that specify the precise link that should exist between those two elements for the rule to be activated).

thanks a lot!
I try to complete all the parameter the each method, You have another idea of how to do this?
PD: I'm working in transformation Model to Model (KDM model to Java Model), for now only with method constructor.

rule MethodDeclarationToMethodUnit
{
from
parametros: KDM!ParameterUnit,
source: KDM!MethodUnit (source.kind = #constructor)

to
target:JAVA!ConstructorDeclaration
(
name <- source.name
,modifier <- variavelModifier
,body <- variavelBody
,parameters <- variavelParameters
)
,variavelModifier:JAVA!Modifier(
visibility <- source.attribute -> collect(f | f.value)
)
,variavelBody:JAVA!Block(

)
,variavelParameters:JAVA!SingleVariableDeclaration(

)

}
