What is being filled into the StrutsForm?
Is it something like:
public class MyForm
{
private String[] interestOptions;
public String[] getInterestOptions(){
return this.interestOptions;
}
public void setInterestOptions( String[] sValue ){
this.interestOptions = sValue;
}
}
And in your Action class you are making sure that interestOptions
are filled in? If so, you are actually blowing out the user's previous
selections by setting the array again. You've got to have a different
variable for the selectedInterests and the interestOptions. And then
you have to have a double #foreach loop looping through both arrays
(unless there is some way to get specific array values by index, which
I think there is but am not sure how to do it).
---------------------------------------------------------------------------
#set ( $index = 0 )
#set ( $interestOptions = ["snowboarding", "skiing", "mountain biking"] )
#foreach( $interest in $interestOptions )
#foreach( $selection in $selectedInterests )
<input type="checkbox"
name="interestsDisplay"
value="$interest"
#if( $selection == $interest ) selected #end>$interest</input>
#end
#set ( $index = $index + 1 )
#end
---------------------------------------------------------------------------
Or, if there is a way to get array values:
---------------------------------------------------------------------------
#set ( $index = 0 )
#set ( $interestOptions = ["snowboarding", "skiing", "mountain biking"] )
#foreach( $interest in $interestOptions )
<input type="checkbox"
name="interestsDisplay"
value="$interest"
#if( $selectedInterest.get($index) == $interest ) selected
#end>$interest</input>
#set ( $index = $index + 1 )
#end
---------------------------------------------------------------------------
Hope some of that helps.

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
