Re: Help required in Ofbiz development - Unable to retrieve parameter using HTTPRequest
Your form contains duplicate inputs for each of your field names, one
hidden for each and one visible (date, number etc.).
When this is submitted, the duplicates will be combined into an array of
values for the given parameter name.
ServletRequest#getParameter will only return the FIRST value in the array
(i.e. your empty hidden inputs).
See the servlet spec for more info, section 3.1:

Re: Help required in Ofbiz development - Unable to retrieve parameter using HTTPRequest
Posted by Avijit Bose <bo...@gmail.com>.
I understood your suggestion. But for knowledge sake.... i have to
pass the field hidden else the fields or parameters will not be
available in the java class. As I am calling request.getParameters
method.... it is expecting some parameters.
Is it so that all the form fields/parameters are available to the
corresponding class file by default in ofbiz?
Pls clarify.
