I have an issue with a seemingly undocumented error

"Error with GrdYear-Height. Expression evaluated to an illegal value."

occurs when running a form..and the during the activate of a page.


Is there a limit to the number of grids you can load at one time?

This is a fairly complex formset..with more than one pageframe and one pageframe has 10 tabs...in order to speed up the load time of the form each page on the pageframe has a container that instantiates (sp?) that contains all the objects on that page....the page in question is built this way but has 14 grids (...no i did not write this code!) the activate of the page
has the following code in it and dies on the ADDOBJECT command giving me the above error...

IF THIS.CONTROLCOUNT = 0
ON ERROR DO app_error WITH error()
THIS.ADDOBJECT("loTrans", "Trans")
THIS.loTrans.VISIBLE = .T.
ON ERROR &gcErrorSet
ENDIF


NOTE changing the system settings to small fonts causes this problem to go away. Moving or resizing the grid in question has no effect.

The other documented causes of this error dont seem to be the cause error. Any help would be appreciated.
