Arithmetics example can't serialize Definition references [message #852987] Sun, 22 April 2012 15:07 Go to next message

I have been trying to write a unit test for validating the
parsing/execution of a definition. However, the project is unable to
serialize references to definitions. The problem seems to be related to
the custom naming of the reference in the LinkingService and
NameProvider included in the project. The string representation
internal to the model includes the arguments in addition to the
Definition name. When serializing this string, the '(' and ')'
characters cause the ID rule to fail.

I've been able to use the debugger to change the qualified name of the
reference and remove the arguments from the string. This allows the
serialization to complete successfully.

What I can't figure out is where and how to change the code to allow the
serialization to work in the first place.

Is there a way to get the serialization to work for cross reference that
have customized strings?

Here is an example.

This is the unit test case:
check(10, "def ten(a,b) : a + b; ten(4,6)");

When running this test, you get the following error on serialization:

java.lang.RuntimeException: ID 'ten(arg1,arg2)' contains invalid
characters: '(' (0x28), ')' (0x29), ',' (0x2c)

Hi,

I have likely the same problem when defining the name of my sadl element (code attached). I have this error:

Have you found a solution for that?
