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.

Objet : Re: [Stripes-users] how to check if error collections not empty
*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?

Hope that helps,

In my JSP page, how do I check if the errors for a field that are
rendered by the stripes:errors tag is not empty?
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
Chris
