Form/Submit tags suggestion
A suggestion,
The form tag wont acept an onsubmit event and the submit button wont accept
an onclick event.
I need to do some processing immediately before submitting the
form(accumulating 120 checkboxes into a single hidden tag so it can be
passed to a form property).
Of course I can just remove the struts submit button and replace with a
standard button but it would be nice to just be able to us the tags and set
the events....
BTW
Can a form property be somehting other than a string??

There has been some code submitted (by Ralph Schaer) to deal with sets
of
checkboxes that I haven't had a chance to add yet ... but better support
for
this is coming.

I think your right. Supporting indexed properties would be a nice
improvement though.

Well its different to the extent of trying to have the ActionForm object be
auto loaded with the data.
AFAIK struts only handles simple strings rather than arrays of strings.

Is this somehow different than assigning all of the checkbox fields with the
same name, and then using ServletRequest.getParameterValues(String) to get
an array of the parameter values?

Thanks,
Sorry should have RTFM....
The hours are long and I am getting tired :-))
On types, I was just thinking of whether there was a simpler way of handling
arrays of controls, ie I have 3 sets of 40 checkboxes allowing someone to
select the type of news they are interested in, I dont feel like having 40
properties on the form object (and in any case it would then break if I
added a new news item) so I have a js function to run over all the controls
and concat the values in to a CSV string which I pass to a single
property(though this is quite slow).
Yea like the client side script auto validation, we are doing this now but
we keep the validation routines in a seperate js file then call the routine
from the onblur for a field or the onsubmit for the form but it would be
neat to have this auto generated

Both of these are legal ... it's just that Struts, like all XML
applications,
is case sensitive and I chose a different capitalization for these
attributes
(see the tags.html file in the "struts-documentation" file for the correct
capitalization).
Try <struts:form ... onSubmit="xxx"/> and <struts:submit ...
onClick="xxx"/>.

At the moment it cannot. On the client side, I don't see a lot of room for
changing this. However, what I'm interested in exploring is the idea of
adding
a "validate" attribute on the input fields like "text" that would generate
JavaScript code to validate things like "this field is required" and "this
field must be a date". On the server end, though, the parameter values are
still going to come in as strings because of the way that the HTTP protocol
(and the servlet API) are defined.
