Can you change the value of the that field at submission with javascript, to a 'default' value which can be considered a flag to the setter method in the bean. I do that in order to by pass getting a null value in my bean which then calls an ejb. In the ejb, if the value is the 'default' I reassingn the variable. Maybe this will inspire a solution?
public void setVariable(String value){
this.variable = (value.equals("default")) ? "" : value;
}

Does this work. Tim Davidson wrote:
Different JSPs edit different fields from the bean, so we would have to write a setAll() method for each page to set only the fields for each particular page. This means moving presentation code into the bean, which is not something we wish to do. Becides this is just moving the '15 setProperty calls setting strings to ""' approach into the bean.

If you are also the bean provider, you could add an additional bean field called something like "all" and in its "setAll() call, initialize all of the particular fields you wish to. This may be more efficient than reinstanciating your bean....

I have a bean on a page, and the user may remove the value of an attribute by using the delete key to remove the contents of a pre-populated text box. On the following page we use <jsp:setProperty...property="*"> or <jsp:setProperty...property="firstName"> to set all the values. This works fine for everything apart from empty strings.
The approach I took to solving the same problem is to remove my session-scope bean and then re-instantiate it:
<% session.removeAttribute("sRefQueryTerms"); %> <jsp:useBean id="sRefQueryTerms" scope="session" class="org.mdibl.ctd.jsp.beans.RefQueryTermsBean" /> <jsp:setProperty name="sRefQueryTerms" property="*" />
I don't know how (in)efficient this is, but it didn't sound any worse than doing 15 setProperty calls setting strings to null (or "").
