how to edit document in JAPE RHS

[<hu...@ti...>]

Hello

I try to change the contend of a document so I use this RHS :

Rule: symbol
(...):mylabel
-->
{
gate.AnnotationSet symbolSet = (gate.AnnotationSet)bindings.get("mylabel");
gate.Annotation symbolAnno = (gate.Annotation)symbolSet.iterator().next();

Long beginIndex = new Long
(symbolAnno.getStartNode().getOffset().longValue() -9);
Long endIndex = new Long( symbolAnno.getEndNode().getOffset().longValue()
+ 10);

try {
  doc.edit(beginIndex, endIndex, new gate.corpora.DocumentContentImpl("new
text"));
}
catch (InvalidOffsetException ex1) {}
}

When this transducer is applyed, the phase symbol never end. What's the
problem?

Thanks.
