[jira] Commented: (WW-3444) JSON plugin thows
java.lang.IllegalStateException when used together with Struts2 Portlet
Bridge
[ https://issues.apache.org/jira/browse/WW-3444?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12990035#comment-12990035 ]
Johannes Geppert commented on WW-3444:
--------------------------------------
I also run into this failure with current sandbox version when using a json action.
<s:url
id="jsonurl"
includeParams="none"
portletUrlType="resource"
namespace="/json"
action="json-search"
/>
If i understand Rene right, it should run with this version and portletUrlType = resource

> Surrounding line 260 [ response.setContentLength(json.getBytes(serializationParams.getEncoding()).length); ] in org/apache/struts2/json/JSONUtil.java makes it possible to get it running, but I guess it should be avoided at all to run into this exception.
