> Struts core 1.3.10 unable to submit single Form file
> ----------------------------------------------------
>
> Key: WW-4534
> URL: https://issues.apache.org/jira/browse/WW-4534
> Project: Struts 2
> Issue Type: Bug
> Reporter: venu b
>
> My requirement is to support uploading multiple files at a time:-
> Getting NPE while submitting Form file thru multipart form
> In Java form I am not using
> private FormFile [] importConfigFile
> because, it throws
> Exception found: java.lang.ClassCastException:
> org.apache.struts.upload.CommonsMultipartRequestHandler$CommonsFormFile
> cannot be cast to java.util.ArrayList
> Hence, without declaring it, dynamically I am using
> Hashtable files =
> adminConfigurationsForm.getMultipartRequestHandler().getFileElements();
> ArrayList list = (ArrayList) files.get("importConfigFile");
> to accept multiple files at a time..
> ----------
> Same Action is working fine, if not File selected
