LookupField need LookupCache to set True?

[cipto_kh]

Now I want to migrate my application using ZeosDBO 6.1.5 to ZeosDBO 6.5.1 (alpha version cvs_13-10-2005) and the problem is:

In the version 6.1.5 if I have a lookup field in my query (TZQuery) I don't need to set the LookupCache property to be True for retrieve data from the LookupDataSet

But, in version 6.5.1 (aplha) I must set the LookupCache property to be True. If the LookupCache property is False my lookup field will blank.

Is it a bug? or is it a new behaviour in 6.5.1??

TIA
