Re: error while submitting form

[Laurie Harper <la...@holoweb.net>]

We'd need to see you JSP to give a more detailed answer, but it looks 
like you're creating a request parameter named 'details' and your 
ActionForm has a property named 'details' that's an ArrayList. Struts 
doesn't know how to convert a string to an ArrayList, so you get an error.

Are you trying to populate that list from the form submission? Or is the 
collision between the request parameter and the form property 
accidental? If the latter, try changing the name of the request parameter.
