 [Acceleo] Warning in query implemented in Java [message #1096513] |

Dear All,
I'm facing at repetitive warnings wrt a simple Acceleo query. The problem is that the warnings are listed in the error log view of Eclipse. And the list becomes longer and longer each time I perform a new generation.
Here is the simple query I use to format comments in C:
[query public formatComment(arg0 : String, arg1 : String, arg2 : String, arg3 : Integer) : String
= invoke('com.spacebel.acceleo.uml.to.c.services.commonServices', 'formatComment(java.lang.String, java.lang.String, java.lang.String, int)', Sequence{arg0, arg1, arg2, arg3}) /]
The associated java method is the following:
public String formatComment(String comment, String tagLine, String startLine, int lineSize)
{
String result = tagLine;
String[] yy = comment.replaceAll("\\r","").split("\n");
for (int i=0; i<yy.length; i++)
{
String line = yy[i];
if (i!=0)
{
result = result + "\n" + startLine;
}
if ((line.indexOf("@image") >= 0) || (line.length() <= lineSize))
{
result = result + line;
}
else
{
int size = 0;
String[] tokens = line.split(" ");
for (int x=0; x<tokens.length; x++)
{
String self = tokens[x];
if ((self.length() + size) < lineSize)
{
size = size + 1 + self.length();
result = result + self;
}
else
{
size = self.length() + 1;
result = result + "\n" + startLine + self;
}
if ((self.length() == 0) || (!self.endsWith("\n")))
{
result = result + " ";
}
}
}
}
result = result + "\n" + startLine;
return result;
}
The warning I have is: "It is strongly recommended not to return directly a String from a Java service in a query taking a primitive as its first parameter in order to ensure the precision of the traceability of each text region generated."
Does anyone know how to eliminate (kill) it ?
Regards;

Hi
Add an extra argument to your query so that it has on EObject to hang on to.
Just delete the irritations in the Problem View.

Hi Ed,
Many thanks for your prompt answer. I used en EObject and it works !
[query public formatComment(arg0 : uml::Comment, arg1 : String, arg2 : String, arg3 : Integer) : String
= invoke('com.spacebel.acceleo.uml.to.c.services.commonServices', 'formatComment(org.eclipse.uml2.uml.Comment, java.lang.String, java.lang.String, int)', Sequence{arg0, arg1, arg2, arg3}) /]
Regards;
