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?

Hello Norbi,

Sorry for the delay, but have been working on other stuff

I set the volatile parameter to "true", but didn't make any
difference. I replaced the @For with a @Foreach and now its working!

Right
There wasn't anything wrong with tapestry, I was calling my submit
listener method before the page properties where being set. I made the
following changes to my .page file

original source

<component id="removeMeters" type="Submit">
<binding name="listener" value="listener:doRemovePermissions"/>
</component>

modified source

<component id="removeMeters" type="Submit">
<binding name="action" value="listener:doRemovePermissions"/>
</component>

I should have assigned by listener to the action property

Hello Norbi,

Sorry for the delay, but have been working on other stuff

I set the volatile parameter to "true", but didn't make any
difference. I replaced the @For with a @Foreach and now its working!

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
