I try to selec one radio button with a dinamik link but the value is null in every moment.

    The solution I posted there still works quite nicely [emoticon:ad09a845b95e4cb28c5d9684a032037c]  The code you've pasted here makes fundamental changes to that construct which would prevent it from working in quite the same way.  Most notably, the icon for a given row both bases its appearance on, and saves the value of, that row's identifier - not just a hardcoded "0" or "1" being saved into the row data.

    I'll note that saving a value directly into the row data will probably work fine for selecting rows (like you have it), but will NOT be sufficient for making it do a "radio button" style "single select", i.e. when one row is selected, any other selected row gets de-selected, etc.  Using your approach, you'd need to have the saveInto overwrite the "1" value in any other rows while writing a "1" into the current row, for this approach to work.

    You need to save 1 in fv!item.notificacion in the saveInto of circle-o a!dynamicLink()

    a!save(fv!item.notificacion,1)

    Is there a specific reason you do not use the selection feature of that grid?

      If you are trying to select only a single row then this code differs from the solution Mike gave in the above thread shared by you, change the showWhen condition accordingly.
