[Exist-open] ExistException : Node data could not be found for node XXXX

[Rajeshwari R. <raj...@in...>]

Hi All,
I have a set of XQuery functions written for my application. Now my 
application requires XML documents to be frequently updated and there is 
an external process which modifies the XML documents. My application is 
unaware of the kind of modifications that is done by the other process. By 
my application needs to query the documents. So I remove document needed 
for modification from Exist's collection and add the document back after 
completion of modification. This is done very frequently. 
Now my application seems to be running fine for few times and throws the 
following kind of exception at other times. The functions and the query 
which threw the exception is as follows. Also after the exception has 
occured in my application, when I rerun the same query in Basic Xquery 
interface of exist, it runs although the results are empty, which is what 
is expected.
Any solutions/corrections for this problem ?
