[annotator-dev] Previously created Annotations not getting loaded

[Apurva Jalit]

I tried to step through the annotator javascript file while loading the
search results that are fetched on initialising the annotator. I found that
an *exception is thrown* in the function: *setupAnnotation* when this
statement is executed: normedRanges.push(Range.sniff(r).normalize(root)).
The error message is : "*Couldn't find offset undefined in element /p[1]*".

Can someone help me understand why this is so? Is it because of this
exception that the annotations are not seen as loaded? The page on which
the annotator is initialised has only one element <p> in the body and
annotator is called on body.

Thanks,
Apurva Jalit
