hi, The answers were a real help. I could get the things to things working...
now when i use: fruits Val :${fruitsId.value} this displays: fruits Val :[apple, banana, orange] but when i use: ${fruitsId.value.size()} its giving compile time errors:tAttributes.jsp(98,16) The function size must be used with a prefix when a default namespace is not specified. I need to get 3 so how should i form the expression? i basically need to use this in < td colspan="{...}" > ... is there any alternative ways of handling this? any ideas pl: help ravi Laurie Harper wrote: > > > fruits KEY <s:property value="#fruitsId.key" /> > > Gets the key from the map entry and displays it; OK here. > > > fruits Val <s:text name="%{fruitsStat.value}" /> > > Gets the 'value' property of the iterator status object and uses that as > a lookup key in the application's message resources.
