I am using com.extjs.gxt.ui.client.widget.form.FormPanel for uploading a file. Now my requirement has been changed and I need to give a new option/button to user for adding more files to upload in single submit?

I tried to add a new FileUploadField() on submit of a button in my FormPanel, but it is not being added in UI.
Please help me and let me know how can I add dynamic fields in a FormPanel?
