Cannot access a arraylist of arraylist

Hi,

I have an arraylist of arraylist. the second arraylist contains two elements
first one string and second one another list.

I was iterating this way and getting the string which is the first element
in the second array list.

imageTemplateNotes ---Arraylist(outer)
itnote ----------Arraylist(contains two elements string, list)

		<#list model.imageTemplateNotes as itnote>
				Image Name = ${itnote.get(0)}
		</#list>

Getting the following exception:

Expected hash. itnote evaluated instead to
freemarker.template.SimpleSequence on line 135, column 48 in
emr_print_html_template.
The problematic instruction:
----------
==> ${itnote.get(0)!""} 

Any help would be appreciated.
