following are two methods for getting parameters from GSP in form of list only:-
even if the variable has only one value, it will be recieved as a list and not as “String”.
List<String> myList = params.list(‘variableName’)
List<String> myList = [params.variableName].flatten()

It is very easy and handy to use Grails <g:uploadForm> tag insteed of using HTML <form> tag or grails <g:form> tag, as you don’t need to set the enctype attritbute to multipart/form-data (as in case of HTML <form> tag or grails <g:form> tag) to work with file upload.
for example insteed of using:
<g:form name="myForm" controller="myController" action="myaction" id="1" enctype="multipart/form-data">...</g:form>
,We can just use
<g:uploadForm name="myForm" controller="myController" action="myaction">...</g:uploadForm>
with all same features!!!
