In my web form, i have many similar fields. I have named all of them the same. for example <html:text property="referenceName" name="someForm"/> and there are five of these. my actionform bean has an array declared for these fields and so hopefully the five fields should populate the array. and in fact it does. but my problem is that if my form is invalidated, and my action class takes me back to the same page the all the text fields show some funny junk something like
instead of the original value that i had entered. (if there was no error, and i access the field through the form i get the correct value).
which is probobaly the memory address for that array cell, i don't know. why is this happening? is there any documentation out there that shows how to deal with this type of form? in my jsp form i have explicitely typed out these five fields and not used any iteration function to display it. does this have something to do with this.
your help will be much appreciated.
