[albatross-users] check boxes again.

[Eric S. Johansson]

it is working better.

however, I still have a major problem with checkbox state presetting.  I can 
either set them all on or set them all off.  then there's the question of 
getting the data back on the state of all the checkboxes.

This is a fragment of the entire form cut down for intelligibility

<al-form action="retrain.cgi" method="post">
...
<al-for iter="line" expr="display_list">

<tr class=<al-value expr="line.value().style">>
<td  bgcolor="#ffffff" align=center >

<al-exec expr="albatross_token = line.value().token">

<al-input type="checkbox" name="albatross_token"  valueexpr="line.value().token" 
  list onclick="CCA(this,'mystery');DownReset();" >

<td><al-value expr="line.value().truncated_score()">
<al-if expr="line.value().list_type != None">
<br>
<al-value expr="line.value().list_type">
</al-if>
</td>
<td><al-value expr="line.value().destination"></td>
<td><al-value expr="line.value().from_address"></td>
<td><a href=<al-value expr="'spamtrap_display.cgi?token='+line.value().token"> 
target="spamtrap_display"> <al-value expr="line.value().subject"></a></td>
</tr>
</al-for>
</table>
<br>
...
</al-form>

as you can see, I feed it with an object containing all the attributes that 
define a line including whether or not a check box should be on or off.  So, 
this is my next cognitive hurdle.  How do I directly turn the checked attribute 
on or off?  or is it only possible using indirect means?
