Advice with reading multiple html:selects
Hello,
I have read the newsgroups regarding multiple selects.
I have a multiple html:select control that starts out empty
I populate the select control by using a textbox and an add button
so it is filled dynamically.
My html:select is:
<html:select property="questionOptions" multiple="true" size="2" />
which comes out like :
<select name="questionOptions" multiple="multiple" size="2"
style="width:500 px; height: 61px"></select>
I have an action Form that has:
private String[] gstrQuestionOptions = null;
public String[] getQuestionOptions()
{
return this.gstrQuestionOptions;
}
public void setQuestionOptions( String[] value )
{
this.gstrQuestionOptions = value;
}
Even in the validate i try the following
System.out.println( getQuestionOptions().length ) and i get
java.lang.NullPointerException
Since the select control is dynamically populated would i have to
use something like request.getParameterValues("questionOptions")
instead?
Thank you

It does not matter about building it dynamically, what matter is what
was selected when the form was submitted.
Only the selected values are transmitted back and they should all come
back in that array.
