Hi Adam,
Yes, I think html:errors is a pretty good validaiton mechanism.
Especially if you use the Struts validation framework (validation.xml,
validator-rules.xml) for
generating your errors.
Yes I am using validation.xml and validator-rules.xml.
For showing errors right beside each specific field that fails the
validation, you will need
to have <html:errors property="property-name"></html:errors> tag beside
each field.
For this question I was more curious about those fields that are being
generated by using an iterator, which means there may be many fields with
the same validation needs, but I won't know how many fields there are.
Basically I am wondering if there is a manner to use error validation to
preform validation on a list that may have from zero to hundreds of
elements. The list that I am using is being created by :
<logic:iterate name="ProdSelectionForm" property="results" id="results">
<html:text name="results" property="numProducts" indexed="true"
/>
Hopefully that question makes sense.
But if you want to show all the errors at once (say above all the fields)
then you can use
<html:errors/> tag as-is.

hope this helps,
thanks for the help so far.
