Same issues on CSS based screens?

jksmurf · 2012-08-25, 03:13 AM

Nope, that works it seems. Funny thing is it did actually save the record, but threw the error anwyay.
and I'm still a massive fan of the non-CSS screens.... :-)

UncleJohnsBand · 2012-08-25, 03:19 AM

Thanks....that will help debug this easier knowing it is working in one.....I probably made a change and didn't port it to the table based screens.

UncleJohnsBand · 2012-08-25, 04:21 AM

Give the attached a try.... should fix it.

All good, you're a star (and you can go back to the beach now :-) )
Cheers, k.

Good you didn't... :-) I seem to have got another error, trying to access the Manage Tab?
Not sure whether it was introduced.

Thank you kind sir ...

Will test it when I can find my Search Tab in Local Login (it sometimes go walkabout after an error, comes back when I restart my PC - I think).
Remote Login has the Tab...
