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
