Re: [Quickfixj-users] Using multiple versions of FIX with Quickfix

[Christoph J. <chr...@ma...>]

Hi,

this is acurrently unresolved problem with the 1.6.0-SNAPSHOT versionof QF/J.
Maybe we will treat all fields with different data types throughout the FIX versions simply as 
StringField in any case. But this has notbeen finalized yet.

Cheers,
Chris.
