Hi all,
Continued working on this problem and have it resolved in the following
Velocity macro.
I'm surprised it didn't already exist being a very common requirement (maybe it
does but I just haven't found it !!)

## Checkbox control. 'Remembers' checkbox choices made by user on previous form
submission.
## $name The control name
## $selectedValues A list of currently checked values
## $labels The list of labels for the options
## $values The list of values for the options
#macro (checkboxGroup $name $selectedValues $labels $values)
## Use a zero-based counter.
#set ( $index = 0 )
#foreach( $value in $values )
#set ( $rendered = false )
#foreach( $selectedValue in $selectedValues )
#if ( $value == $selectedValue )
<input type="checkbox" name="$name"
value="$value" checked>$!labels.get($index)</input><br/>
#set ( $rendered = true )
#end
#end
#if ( $rendered == false )
## the current checkbox still hasn't been rendered it,
so it must be rendered (unchecked)
<input type="checkbox" name="$name"
value="$value">$!labels.get($index)</input><br/>
#end
#set ( $index = $index + 1 )
#end
#end
----------------------
It can be used with the following example
#set ( $interestLabels = ["snowboarding",
"skiing", "mountain biking"] )
#set ( $interestValues = ["snowboarding",
"skiing", "mountain biking"] )
#set ( $selected =
$!newsletterForm.interestsDisplay )
#checkboxGroup ( "interestsDisplay" $selected
$interestLabels $interestValues )
NB. $selected is a String[] in associated Struts form.

Hi all,
Another newbie question here. I'm working with a StrutsForm that holds
checkbox selections in a String[] as I normally do when working with struts.
In the form, I'm having difficulty pre-selecting checkbox options that the user
set on a previous request, so far I have....
#set ( $index = 0 )
#set ( $interestOptions = ["snowboarding",
"skiing", "mountain biking"] )
#foreach( $interest in $interestOptions )
<input type="checkbox"
name="interestsDisplay" value="$interest" #if (fillInTheBlanks) selected
#end>$interest</input>
#set ( $index = $index + 1 )
#end
Can somebody please tell be how I 'fillInTheBlanks'? Or point me to a resource
on the web that would help me, I can't find a think on the velocity site.
Many thanks
Robin
