I am running tests on some Utilities data. Each layer has a few subtypes and many domains. I am successful in creating the .axf for ArcPad 8 and it seems to work just fine. When I try to check-in the data, the ArcPad Data Manager will show me which layers have changes, but it hangs for a while (60+ minutes) and ultimately fails to import the data (on my local PC). No changes are made to the source .GDB schema while the data is checked-out. I have 30 layers I would like to be checked in and out, but not all layers will be edited all the time. I am wondering if the complexity of the subtypes and domains are bogging down the system. Anyone have an experience like this and/or a solution besides reinstalling ArcPad (if that would even work in this instance)?
