Hi,
Thanks for the pointer - although Im not sure this is a case for those tags
(at least I cant work out how to solve my problem using them!)
My issue is that I don’t know how many multibox sets I will need on my form
(i.e. it has to have a dynamic number of multiboxes, each with a dynamic
number of name/value pairs).
At present my Action form subclass uses:
private java.util.ArrayList attributeValues = new java.util.ArrayList();
private java.util.ArrayList attributeStatus = new java.util.ArrayList();
to store the possible values and 'check status'. The ArrayLists each hold
LabelValueBean[] and String[] respectively.
This allows me to display a variable number of multiboxes as follows:
<html-el:form action="/AdminEditProductAttributes">
<c:forEach items="${modifyAttributesForm.attributeNames}" var="heading"
varStatus="i">
<c:forEach items="${modifyAttributesForm.attributeValues[i.index]}"
var="valuePairs" varStatus="j">
<html-el:multibox property="attributeStatus[${i.index}]">
${valuePairs.value}
</html-el:multibox>
${valuePairs.label}
</c:forEach>
</c:forEach>
<html-el:submit value="Update Attributes" />
</html-el:form>
This generates html:
<form name="modifyAttributesForm" method="post"
action="/store-modules/admin/AdminEditProductAttributes.do">
<h3>Size</h3><br>
<input type="checkbox" name="attributeStatus[0]" value="0">S
<input type="checkbox" name="attributeStatus[0]" value="1">M
<input type="checkbox" name="attributeStatus[0]" value="2">L
<h3>Colour</h3><br>
<input type="checkbox" name="attributeStatus[1]" value="0">Black
<input type="checkbox" name="attributeStatus[1]" value="1">White
<br><br><input type="submit" value="Update Attributes">
</form>
So the display works fine - I just cant work out what setters in need in my
form subsclass. The best I can get is a single value for each multibox being
passed using:
public void setAttributeStatus(int i, Object in){
this.attributeStatus.set(i,in);
}
Any ideas?
TIA
