Re: [Stripes-users] how to check if error collections not empty
Hi,
There is no such function for messages. But you can do that easily in EL.
For example, if you save your message like this:
LocalizableMessage message = new LocalizableMessage(some_message);
context.getMessages(my_key).add(message);
Then the EL will look like this:
${!empty request['my_key']}
I think this will work even after a redirect since messages are saved in
FlashScope.

*facepalm* I didn't even see that and I've had the JDoc open for the last
couple of days.
What about for the messages collection? I don't see anything analogous to it
there.

Hi Chris,
Perhaps use the hasErrors() JSP function from the Stripes taglib?

In my JSP page, how do I check if the errors for a field that are

In some places I need to display them under the field and use a line
break before them, and in some places I need to display them next to
the field without the line break. Due to this I can't use the
stripes.fieldErrors.X properties because it affects everything.
What I need to do is conditionally insert the line breaks in the places
where it is appropriate. I am assuming they are hidden as a request
attribute, but what is the key for them? What about the collection that
stripes:messages renders?
Thanks

Re: [Stripes-users] how to check if error collections not empty
Hi,
You can also check for errors using:
c:if test=${not empty actionBean.context.validationErrors}
s:errors /
/c:if
Similarly using the following code may also work for messages (not tested):
c:if test=${not empty actionBean.context.messages}
s:messages /
/c:if
