Ville,
It works like a charm. I appreciate your help. Thanks.

Hi,
the given tml is missing encoder for the inner loop. Without this T5 uses
the default approach which is the highly inefficient
serialize-whole-thing-to-form-data.
This encoder can be constructed in the bean itself (resident) but imho
should not be there, so the best approach (afaik) is to construct it in the
page based on the data that resident contains (So that one encoder is
created per resident for the profiles loop.).
Add the encoder and if this doesn't work attach the associated java code
snippet also

Hi all,
This is somewhat complicated so bear with me.
I'm trying to create a bean with a variable number of fields, each which
has a name and an associated select box to set various properties.
The tml looks something like this:
.....
<tr t: type="AjaxFormLoop" t:sources="residents" t:value="resident"
t:encoder="encoder">
<t:submitnotifier>
<td><input t:type="TextField" t:value="resident.name" ></td>
<t:loop source="resident.profiles" value="profile">
<td><select: t:value="profile.selection"
model="profile.model" encoder="profile.model" /> </td>
</t:loop>
</t:submitnotifier>
</tr>
Resident and profile are standard beans except that resident contains an
ArrayList of profiles that is accesses through getProfiles().
This all works pretty well except that Tapestry 5.0.18 tries to
serialize the profile bean (I get errors unless I make it extend
Serializable) AND it appears to set the selection on another instance
of the profile bean. I suspect that tapestry serializes the profile
bean, unserializes it to create it's own copy, then changes selection
on it's own copy. My bean never sees the updated result.
The work around is ugly - to store the profiles list in the session, the
retrieve it and update the actual bean in in the profile.setSelection()
method.
My question is is this a bug in tapestry or am I doing something wrong?
Is there a better way to accomplish this?
Thanks!
