Listboxes - force a selection

datanibbler — Mon, 16 Feb 2015 11:23:57 GMT

Hi,

I havean app where it is essential that in a listbox I have added on the GUI, there is a selection at all times - I could as well code a default in case there is none, but I found it easier to force a selection in the listbox

<=> only it doesn't seem to work yet.

That might be connected to the fact that I am still testing the script and not always executing it to the end?

Can you confirm to me whether or not this feature is known to work reliably? => depending on that, I will hard-code a "Plan B" in the variable controlled by that listbox or not.

Thanks a lot!

Best regards,

DataNibbler

Could you use the 'Always One Selected Value' option in the listbox properties?

Hi Charlotte,

that is exactly the option I use - but it seems that every time I execute the script with a breakpoint and don't let it run to Finish, the option is reset.

true because the field is empty when you break the script execution (no values) so there is none to select. In normal reload, it will not be reset

If the reload is too long - use debug mode limiting load to a small number of records.
