How to handle checkboxes in rows of repeated grid

[shiningstar]

<http://discuss.orbeon.com/file/t375838/Capture1.png>
Hi Alex,
Let me explain my requirement. I want to have only one check for first
choice in this repeated grid. I check first choice for 1st row of repeated
grid and then for 2nd row, I also check the first choice of 2nd row. As the
result, the 1st row of this grid will be automatically unchecked. Please
guide me. :D

Hi Shine,

In Orbeon Forms, we don't recommend users interacting with one field changes
the value of another field (unless that other field is readonly), but you
can mark both fields invalid if they have the same value selected:

Assuming your field is named `choice`, you can achieve this with the
following validation expression:

not(xxf:split(.) = (//choice except .)/xxf:split(.))

You'll let me know if this works for you!

And the source of the form created for testing, in case you would like to run
it in Form Builder:

Thank you Alex for guiding me. For single checkbox in repeated grid, which
validation expression can I use?

Hi Shine,

In the case of a single checkbox, I imagine that you want a most one line in
the repeated grid to have that checkbox checked, correct? If so, I think
pretty much the same expression would work, except you don't need to the
calls to `xxf:split()` in that case, that is: `not(. = (//choice except
.))`. Does that work for you?

Hi Shine,

Did you get a chance to try that expression on a single checkbox? If so, did
it work for you?
