Hi,
My grammar has a field 'variable'. The xtext grammar is as below:

VariableType:
"varType" (name=ID)? "{"
"variable" variable=SignedDouble
"}"
;

SignedDouble returns ecore::EDouble:
('-')? (INT '.' INT)
;

terminal INT returns ecore::EInt:
'0'..'9' ('0'..'9'|'_')*
;

xcore file is as below:

class VariableType{
String name
Double variable
}

When I enter variable 1.0 in my editor, it shows the below error message :
Multiple markers at this line
- Couldn't convert 'null' to EDouble.
- mismatched input '1.0' expecting RULE_INT

Could anybody tell me what the problem is?

Thanks in advance
