---------------------------------------------------------------
Here is what it all boiled down to. There is function called encodesequencemap
in the static context class which has adds name test ("*") to the sequencemap.
The function first looks up the sequence through a lookupsequuence function. In
order for encodesequencemap function to add the name test to the sequence map
the lookupsequence function must return -1.
However, the lookupsequence function can not return -1. It return -1 only when
parent(static context) is null. However, when the parent sequence map contains
all the values including the name test so it instead returns the code of the
name test and not -1.
Now when it gets back to the encodesequencemap code is not -1, so it can not
add the name test to the sequence map. But sequence map. Since the sequence map
is empty one of the printer functions runs into null pointer exception in an
atteempt to print this empty seequence.
How can I deal with this?
I hope I could explain the problem. Please let me know if there is any part
that needs clarification.
