Hello Daniele,
Thanks for your reply. The sub-component is actually a
WOSwitchComponent that is dependent on the subclass of entity that is
loaded in the page. This is the first subclass that I have made that
requires an uploaded graphic associated with the metadata. The date
uploaded was just a poorly thought out example of additional metadata
in my form ;). If anyone is curious, the pattern is much like Chuck
hints at in the last paragraph of this mailing list post: http://
lists.apple.com/archives/webobjects-dev/2004/Oct/msg00357.html
I was hoping that there was an easy entry point in a subcomponent to
set values in the EO before the sub-component's values passed to the
main component when it saved. If it is impossible, I'll just add the
graphic to the main form as you have suggested so that every entity
with that parent class gets an optional graphic element as well.
Thanks again,
David

I have a sub-component inside a form that contains a WOFileUpload.
<form>
Name
Address
<uploadcomponent>
WOFileUpload
Date of upload
</uploadcomponent>
Submit
</form>
Normally I set the values in the database using a method that
evaluates the bindings in the WOFileUpload when I submit the form. In
this case I can't do that because the submit button is in the parent
component. How can I programatically set attribute values in a sub-
form when the parent form is submitted?
David, I really don't see a good reason to split you data in two
component: if you have one submit, the best choice would be to have
the entire form inside the subcomponent.
Another way would be to set the form as Multiple submit, and create
two submit: one for the FileUpload, One for the other data to save.
I.E.
YourMainComponent Start
<wo:WOForm>
<wo:WOTextFileds value="$name" />
<wo:WOText value="$address" />
<wo:UpLoadComponent />
<wo:WOSubmitButton action="$saveAllData" />
</wo:WOForm>
YourMainComponent End
UpLoadComponent Start
<wo:WOFileUpload /> //I don't remember the binding for this...
<wo:WOSubmitButton action="$uploadFile" />
UpLoadComponent End
You can see I don't insert Date of Upload, because I've not
understand what that was: if it is an input for the date is
useless, because The date is the moment when the submit is press,
if it is a String with the current date, you can display it after
the submit of the subcomponent, in place of the WOFIleUpload
