Hi, Xiaoqiang.  Thanks for confirming for me.  I finally figured out
what the issue was.  In my test pcaspy IOC, on init I am attempting to
clear the "UDF INVALID" flags with the following:

     for k in pvdb:
         driver.setParamStatus(k, pcaspy.Severity.NO_ALARM, pcaspy.Severity.NO_ALARM)

In earlier pcaspy versions this was sufficient to clear the flags
without causing any additional odd behavior.  I see now that with 0.6
and later the issue I need to additionally call updatePVs() after the
above:

     driver.updatePVs()

Is this the right thing to do?  Is there a cleaner way to clear the
initial "UDF INVALID" flags?  And why is the "UDF INVALID" set
initially anyway?

Thanks so much for the help.

jamie.
