I would like to check if a collection is empty and if
not, print some messages. Is there a tag to check if a
collection is empty in my JSPs?
Right now, this one works
webwork:if test=errorMessages
There are Errors like
.
/webwork:if
is there a better way or another tag to do this?
Thanks
for example if I use:
message key=user.name.errors.required/message
and the key doesnt exist ill just get blank error, I know i could put a message in there myself to display if the key is
not valid but can we change it so that if the message is blank like it is now it just displays
thats the only way iv'e seen it done, but you could use also
test=errorMessages.isEmpty(),
i believe test=errorMessages will just just if the property is null.
