Error executing link validation between EMF models [message #1748380]

Hi,

I'm getting the following error when trying to perform a link check between EMF models: 'Line: 1, Reason: mismatched input: 'context' '

Can anybody help me?

I'm trying to follow this tutorial: https://www.youtube.com/watch?v=6bS1mxGrPIM

Follows the contents of the EVL file:

context personhouses{

constraint DoNotLetTheirOwnHouse {

guard : self.type = PersonHouseRelationshipType#Lets
check : not self.person.owns(self.house)
message : 'Person' + self.person.name + ' appears to let'
+ self.house.address + 'while (s)he owns it'
}

}

operation Person owns (house : House) : Boolean {
return PersonHouseRelationship.allInstances.
exists(phr|phr.person = self and phr.house = house
and phr.type = PersonHouseRelationshipType#Owns);
}

Your EVL code doesn't seem to have any syntax errors (just tried copying and pasting it on an .evl file). Are you sure you are using an EVL launch configuration, and not an EOL one? I can only guess you're using an EOL one and Epsilon is getting confused trying to parse your EVL as EOL.

If you're using an EVL one and it still doesn't work, attach it over here and I'll have a quick look.

Hi,

Yes, I'm sure I'm using the EVL launch configuration.

Take the look:

That screenshot shows you're using an EPL (Epsilon *Pattern* Language) configuration, not an EVL (Epsilon *Validation* Language) configuration :-/. You should use an "EVL Validation" one.
