Data is not getting flushed

Hello I have added a .CSV parser and a dissector. It is observed that if my .CSV file is opened as the first file in wireshark, then packet dump is proper as expected.

But if an other file is opened first and then my .CSV file is opened then packet dump is of the previous data. This is not the behaviour with other sample files.

I have verified that the frame buffer is getting filled with data properly from my XXX_read and XXX_seek functions.

It looks like some flag issue.

Can anyone help me to resolve my issue?

thanks in advance krithiga
