Hello all,
I've got two @For loops inside a @Form tag. Each @For loop is printing
the part of the contents of the MeterCB class, two text fields and one
checkbox. During the rewind process tapestry is not recognizing the
fact that checkboxes in the second @For loop are being selected.
I've already spent too much time trying to fix this problem :( has any
body fixed this problem or has a work around?
I've enclosed the source code ...
