Re: PMAP decoding issues
Augusto Acuña / Viridian
8 Apr 2009 4:40PM ET Thanks to all. I couldn't solve this issue yet.
The exception message that OpenFast is throwing is:
org.openfast.error.FastException:
The presence map BitVector [00000110 00001101 10100000] has too many bits for the group SingleLegReferenceInformation.
So I'm assuming that the api is detecting a SingleLegReferenceInfo message ( TID 4) but suddenly something wrong happens with the pmap.
These are the first 32bytes of the message in hex:
c0 81 23 38 16 80 81 02 31 7a c5 c0 f8 7f fc 84
80 c0 04 5d d4 b1 01 6c 1d ca 4e 4f 56 ce 4f d0
Can anybody guess what's wrong ?
