Hi everybody,

We have a form with a pageframe. Each page of this pageframe has a container with business objects and lots of controls. The container is instantiated in run-time. In one of the button on this container we call a method with the following code:

LPARAMETERS tlEnabled

WITH THIS

	.SETALL('TabStop', tlEnabled)

* Setting ReadOnly for drop down combos has no effect due to VFP combobox design
	.SETALL('style',IIF(tlEnabled,2,0),'cboViscodes')
	.SETALL('style',IIF(tlEnabled,2,0),'cboStates')
	.SETALL('style',IIF(tlEnabled,2,0),'cboCountry')

	.SETALL('ReadOnly',!tlEnabled)
	IF NOT tlEnabled
		.SETALL('lRefresh',!tlEnabled) && we need to have this property for comboboxes to refresh them properly
	ENDIF
ENDWITH

This code worked perfectly in VFP8. In VFP9 it doesn't make the controls accessible, e.g it looks like ReadOnly is still off.

We tried to test this problem on a new simple form. I created a form, bring a table into DE of the form (visually) and grab few fields so the controls were created for me. Put the button on the form with this code

thisform.lSwitch =  not thisform.lSwitch
thisform.SetAll('readonly',thisform.lSwitch)

and I'm having an error:

Property setting will not take effect until data environment reloaded (Error 1739)

You attempted to set a property on a data environment object (Relation, Cursor) while the data environment is loaded. The property value will be stored with the object, but the property will not take effect until the data environment is unloaded and then reloaded.

So, how can we make our code work? Is it a bug in VFP9?

Thanks a lot in advance.
