#foreach issue

[Mo]

Hi Forum,
I'm returning the Map of objects on call of getLiabilitiesMap() if I print $liabilitiesMap output is - showing proper count of 4 elements, but if I use

#foreach( $temp in $liabilitiesMap )
$temp
#end

I get a blank output with warning on console as -
[ WARN] (org.apache.velocity.app.VelocityEngine): Could not determine type of iterator in #foreach loop at [0,0] in template ConfirmationEmail.vm

Any directions on this issue?
Thanks,
Mo.

Map doesn't implement Iterator, you need to iterate over the set of values, set of keys for the entrySet.

for #forEach ($temp in $liabilitiesMap.entrySet)

would make $temp a Map.ENTRY object,

for #forEach ($temp in $liabilitiesMap.values)

would make $temp one of the values in the map,

for #forEach ($temp in $liabilitiesMap.keySet

would make $temp one of the keys in the map.
