This issue seems to pop up in our environment from time to time and trying to figure out how to fix it once and for all.
We have a page with a form that pops up modal window with a form specified as well. When we try to submit, we get the following exception: java.lang.IllegalStateException: ServletRequest does not contain multipart content. One possible solution is to explicitly call Form.setMultipart(true), Wicket tries its best to auto-detect multipart forms but there are certain situation where it cannot. at org.apache.wicket.protocol.http.servlet.MultipartServletWebRequest.<init>(MultipartServletWebRequest.java:113) at org.apache.wicket.protocol.http.servlet.MultipartServletWebRequest.<init>(MultipartServletWebRequest.java:83) at org.apache.wicket.protocol.http.servlet.ServletWebRequest.newMultipartWebRequest(ServletWebRequest.java:500) at org.apache.wicket.markup.html.form.Form.handleMultiPart(Form.java:1668) at org.apache.wicket.markup.html.form.Form.onFormSubmitted(Form.java:862) at org.apache.wicket.ajax.form.AjaxFormSubmitBehavior.onEvent(AjaxFormSubmitBehavior.java:135) at org.apache.wicket.ajax.AjaxEventBehavior.respond(AjaxEventBehavior.java:177) ... Setting Form.setMultipart(true) on either form has no affect. We are running Wicket Version 1.4.7. Is there a fix for this issue? Is this JIRA Issue related??? https://issues.apache.org/jira/browse/WICKET-2749
