Oracle Forms

Hi all,

This is my first post so please bear with me if I haven't provided sufficient information or am unclear at all.

I'm using Forms Builder (Web) on a 10g Database. I have a number of database and non-database items as part of a data block.
My problem is that, when I enter a value in any field and click the query button, I get a FRM-40212 Invalid value for field error on my radio group (disabled, non-database item that is programatically populated in the post-query and list-changed triggers only). When I click ok, I get a FRM-40222 Disabled Item Failed Validation error on the same radio group.

This does not happen if I click the 'Enter Query' button before entering values into fields, however I don't want my users to encounter this error if they try to query without clicking on 'Enter Query' first.

I'd like to know why exactly does this error happen - what does it mean?
I've read in other forums that setting the item's Required property to false solves this issue. But how can I do this with a radio group? And if it's not possible, does anyone have any suggestions for other workarounds?

Thanks in advance,

Abigail
