Hi I use tomcat 3.2 on various platforms. My problem is this: when modifying a bean's properties through a jsp form, I would like a property to be cleared if the corresponding form field is cleared. The introspect(...) method in the JspRuntimeLibrary does not do this for me.
I searched the archives and found that according to the spec, if a request parameter has no value, then the corresponding bean property is not to be modified (see http://w4.metronet.com/~wjm/tomcat/2000/Jul/msg00481.html). Oh well. That still leaves me the problem of handling empty fields. I could 1) Go through the list of request parameters myself and clear the corresponding bean properties if parameters have no value. This feels like duplicating some of what the introspectHelper(...) method does. 2) Use javascript to record all empty fields to a hidden field at submit time. This is rather cumbersome and requires a little extra code in the form bean. I've used both but neither is very satisfying. So, to summarize, is there a preferred or recommended way of doing this that anybody knows of?
