I think I remember this error from way back when, but I cannot find my info on it. It happens seemingly randomly. Form foxpro myForm will be running fine for user after user, then suddenly this will pop. Other users can can continue on same form.

Sound familiar?

Hi Tuvia,

If you refer to the last lines of an awAJAX error, never mind, it's meaningless.

The actual result is: awajax.lSuccess(.f.): Error detected at code line #16,142 of method 'awajax.cformdspropsalias' "form properties table can't be found" C:\clients\XXXYYY\app\temp\6TK138O6I_6tk138o6i_welcome4_scx_Old.DBF

I wonder if it is related grids. Maybe once out of every 50 times it will give an error that the last column of a grid is missing. For a 4 column grid it would be:

awajax.lSuccess(.f.): Error detected at code line #11,597 of method 'awajax.propsrestore_props'
"awhtml.fxp!Awhtmlgen.grdrestore_() - Object 'Column4' can't be found in Object {BaseClass: "Grid",

The second error is less frequent. they both started occuring about the same time.

Missing columns are almost always due to a use in (.recordSource) without a prior .recordSource = ''

Bingo. Thanks. The memory is not quite what is used to be,
