If you're worried about hitting a non-existent array member, do this:
${(seq[n].myFieldOfInterest)!"Not Found!"}
Note that braces ().

I just confirmed it, it does.
To test, I edited party/webapp/partymgr/party/findparty.ftl
line 87 has the following:
<#list roleTypes as roleType>
<option
value="${roleType.roleTypeId}">${roleType.get("description",locale)}</option>
</#list>
after the subsequent td endtag, I added...
<td>${roleTypes[0].get("description",locale)}</td>
and was givin the correct description in a third column on the main
page of the party application.(localhost/partymgr/conrol/main)
So in your example, ${seq[0]} will print the first hashmap of the
collection seq. If you wanted to access a specific field of the
hashmap, you would use ${seq[0].myFieldOfInterest?if_exists}

hmm..IIRC correctly, try ${seq[0]} x is the current object in the
index.

I have this ftl snippet code.

How can i retrieve just the certain index from seq list (say x[0]
and
x[1])
??
