[SOLVED] Error: Multiple markers at this line -Duplicate ... [message #1118448]

Greetings to all!

I am having a problem when trying to parse a file instance having multiple string instances that are the same. I get the following error:

Multiple markers at this line
-Duplicate Spacecraft_Type 'NamingA'
-Duplicate Spacecraft_Type 'NamingB'
-Duplicate Spacecraft_Type 'NamingC'

The simple grammar I have written is the following:

Active_Spacecraft:
'Active Spacecraft'
(st2+=Spacecraft_Type)+
;

Inactive_Spacecraft:
'Inactive Spacecraft'
(st1+=Spacecraft_Type)+
;

Spacecraft_Type:
('ASc.Active Spacecraft_Type'
(ast=STRING','|ast=STRING)
'end')|('ISc.Active Spacecraft_Type'
(ist=STRING','|ist=STRING)
'end');

That is, each of the nodes Active_Spacecraft and Inactive_Spacecraft shall contain a set of nodes each called Spacecraft_Type and containing a list of string type values. I must note that in the file instance I am parsing there exist string values that are identical.

I have changed the feature name for each rule but with no success. Is this problem related to "unique name" value checking from xtext? If yes how can I disable this property?

Will be waiting for your kind reply!

Hi Christian and thank you for your kind reply.

I have found the fragment you mention in the .mwe2 work flow and have commented it and that solved the duplication error problem.

// java-based API for validation
fragment = validation.JavaValidatorFragment {
//composedCheck = "org.eclipse.xtext.validation.ImportUriValidator"
//composedCheck ="org.eclipse.xtext.validation.NamesAreUniqueValidator"
}

Btw, I have noticed in other posts that you are really active in this forum and a real savior for others having various problems. I think we should be all grateful for having around people like you. RESPECT!
