Jasper Rosenberg created WW-4514:
------------------------------------
Summary: DefaultUrlHelper.buildParametersString appends just ? if
collection is empty
Key: WW-4514
URL: https://issues.apache.org/jira/browse/WW-4514
Project: Struts 2
Issue Type: Bug
Components: Core Actions
Affects Versions: 2.3.24
Reporter: Jasper Rosenberg
Priority: Trivial
Attachments: DefaultUrlHelper.patch
DefaultUrlHelper.buildParametersString() checks that it has parameters to
append before adding the first "?"/"&", but if the only parameters are empty
Iterables/Arrays, then it shouldn't do that.
I'd suggest adding the new query string to a StringBuilder, and then if it is
non-empty, append that with the separator to the link at the end. (See patch)
