Thanks, Mike:
Just google into this link myself a few minutes ago. Things change
quickly with struts :-(
http://www.nabble.com/-PROPOSAL--Deprecate-or-remove-Dojo-plugin-td18573704.html
It seems for ajax, better learn another tool like JQuery or something.
Quite confusing they still have the line "*First-class AJAX support*" on
the homepage and no warning in the migration guide from 2.0.x to 2.1.6.

I think those tags are deprecated, so I'd be cautious of using them.

Subject: struts2.1.6 dojo ajax tags conflict with fileupload interceptor?
repost, since last one went as a reply under another topic
I am trying to use struts2.1.6 dojo tags (<%@ taglib prefix="sx"
uri="/struts-dojo-tags" %>) within a multipart form which also uses
fileupload interceptor, but with no success.
My dojo tags is to populate a second drop down based on selection of
first dropdown. This works fine on regular form. But once the form
becomes mulitpart with file uploads, dojo tags stop working. Core
elements from the form looks like this:
<%@ taglib prefix="s" uri="/struts-tags" %>
<%@ taglib prefix="sx" uri="/struts-dojo-tags" %>
<jsp:include page="/includes/struts2/header.jsp"/>
<head>
<sx:head parseContent="true"/> </head>
<script language="JavaScript">
function show_courses() {
document.a_form.selected_userid.value =
document.getElementById("for_id_list").value;
dojo.event.topic.publish("show_courses");
}
</script>
<s:form action="%{actionName}" method="post"
enctype="multipart/form-data" theme="simple" id="a_form" name="a_form">
<s:select list="mygroup" name="for_id_list" id="for_id_list"
listKey="key" listValue="value" name="scheduledFor"
value="scheduledFor" onchange="show_courses();return false;"/>
<s:file label="attach file" name="upload" value="uploadFileNames"/>
<s:hidden name="selected_userid"/>
<s:url id="d_url" action="CourseAction"/>
<sx:div id="course_list" href="%{d_url}" listenTopics="show_courses"
formId="a_form" >
</sx:div>
</s:form>
There is the normal fileupload code in Action class like below:
private List<File> uploads = new ArrayList<File>();
private List<String> uploadFileNames = new ArrayList<String>();
private List<String> uploadContentTypes = new ArrayList<String>();
private void uploadFiles() {
try {
if (uploads != null) {
for (int i = 0; i < uploads.size(); i++) {
File theFile = new File(getFileSavingPath() +
uploadFileNames.get(i));
FileUtils.copyFile(uploads.get(i), theFile);
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
Does anyone have experience using dojo tags successfully with file
upload interceptor? Or is there some better approach for ajax in struts2?
Any suggestions and pointers are greatly appreciated!
Have a good day!
