Using html:errors with a field that is iterated.

[Adam K]

Hi all I am using struts 1.2.9 and starting to work on error validation.  So
far I have my login page using:

html:errors property=username/html:errors
etc etc etc.

I was wondering firstly Is this still the best manner in which to display
errors ?


The second question which has more to do with the title is
How does one use error validation on fields that are iterated ?

As an example if I have 3 fields where a team has to enter a score, I want
to ensure that the only values that are entered beside each field is a
number.  If any of those fields have other than a number I want the error to
appear only beside that particular field.  Is this something that can be
done with error validation ?  I am looking around for examples but most
examples are quite dated and I am trying to use the best things available to
me.

thanks in advance.

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.

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.

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.

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.
