Please correct me if I am wrong but I think all the setters in your form
beans need to take Strings as parameters.
I don't think Struts provides a way as yet to convert Strings into objects.
I have got to check whether 1.1 addresses this issue.
Everybody in Struts (except guys who did cgi programming) trips over this. I
wonder why can't they they explicitly mention this in the ActionForm
documentation.

Subject: Re: Help with Arrays of text fields
I've done something similar with hidden fields but have not tried to
repopulate them. I had several hidden fields named "required". My
ActionForm looked like this:
private String[] required;
public String[] getRequired(){return required;}
public void setRequired(String[] required){this.required=required;}
Struts successfully filled the string array with the values from each hidden
field.
Hope this helps.
