This problem can occur if you call any functions in your view, open the view NODATA and then subsequently requery it to populate it. The view will build itself based on the first record in the table to determine structure.

For example, if you have a function that takes the value of a field and returns some other value, the structure will initially be built using a blank value (datatype dependent). If the function returns different values based on the value passed in, this would cause the error.

Ex.
function myvalue(puValue)
local luretval
if puValue = 0 then
   luretval = 0
else
   luretval = 100/puvalue
endif
return luretval

If the value passed in is a numeric 5,2 then the output with real values will be 5,2. However, when opening the view initially the structure will be numeric 1. ERROR!

HTH.
