Hi all,
I've got some troubles with QuickFix as title says. As usual, here is a short example showing what I'd like to do and what the problem is.
Here is the grammar :
Model:
(arithObjects += ArithObject)*;
ArithObject :
name = ID '=' exp = Expression ';';
Expression :
AddRule;
AddRule returns Expression :
MultRule
( {Add.left = current} '+' right = MultRule
| {Sub.left = current} '-' right = MultRule)*;
MultRule returns Expression :
TerminalExpression
( {Mult.left = current} '*' right = TerminalExpression
| {Div.left = current} '/' right = TerminalExpression)*;
TerminalExpression returns Expression :
Reference | '(' Expression ')' | Constant;
Constant returns Expression:
{Constant} value = INT;
Reference :
referenced = [ArithObject];
So I've got no problem with quickFix using IModification. For example, if I want to forbid the use of ID "x" for any ArithObject, I add this check :
@Check
public void checkNoXName(ArithObject o){
if(o.getName().equals("x"))
error("name is x",o,ArithPackage.Literals.ARITH_OBJECT__NAME,NAME_IS_X);
}
and this method to my QuickFixProvider :
@Fix(ArithJavaValidator.NAME_IS_X)
public void fixName(final Issue issue, IssueResolutionAcceptor acceptor){
acceptor.accept(issue,
"Name is x",
"...",
"",
new IModification(){
public void apply(IModificationContext context){
IXtextDocument xtextDocument = context.getXtextDocument();
try{
xtextDocument.replace(issue.getOffset(), 1,"y");
}
catch (Exception e){}
}
}
);
}
This works fine.
Now I want to do this using an ISemanticModification, so here is the code, supposed to do the same as above :
@Fix(ArithJavaValidator.NAME_IS_X)
public void fixName(final Issue issue, IssueResolutionAcceptor acceptor){
acceptor.accept(issue,
"Name is x",
"...",
"",
new ISemanticModification(){
public void apply(EObject element, IModificationContext context){
ArithObject o = (ArithObject) element;
o.setName("y");
}
}
);
}
But when I select this quickFix in the popup, i've got this errors and can't understand why and how to solve this :
