EML/ECL example problem [message #588824]

Hi,

I've just started using Epsilon and I'm particularly interested in ECL for comparing models. I run the Heterogeneous Model Merging with ECL/EML example (from the examples on the epsilon site) in eclipse, and I get an error on the line:

t."alias".exists(a|a.name = s.name);

in the Comparison.ecl file. Eclipse says:
multiple markers at this line:
-mismatched input:'alias'
-no viable alternative at input 'alias'
-Line Breakpoint:Comparison.ecl [line:16]

Can someone tell me what's wrong or what can be done?

Bogie

Hi Bogie,

Since 0.8.8 we've changed the escape character for reserved words (i.e.
alias) from " to `. Therefore, t."alias" needs to become t.`alias`
instead. I'll update the example in the SVN shortly.

Cheers,
Dimitris
