You happen to know what part of Transfer the bug is affecting? I'd be
happy to take it up with the guys at Railo, just need to know what I
should be asking.
Is Transfer checking the column type of the objects and then using
that type to wrap them with a cfsqltype? Does that mean Railo is not
providing this information to Transfer, so then it is falling back on
the default cfsqltype for numeric, which in this case happens to be
float?
Basically, is Transfer unable to get the type from Railo so it runs
this:
<cfelseif block.mapparam.type eq "numeric">
<cfqueryparam value="#value#" cfsqltype="cf_sql_float"
list="#param.list#" null="#param.isNull#">
And sets it to float?
Thanks!
