simulating click on table row

[wgworek]

Hi!

I'm using rich:dataTable with

<a4j:support id="showDetails" event="onRowClick" reRender="detailsOfUser" actionListener="#{userList.editAction}">
 <f:attribute name="user" value="#{user}"/>
</a4j:support>

I would like to test it. Unfortunatelly it cannot be done by RichFacesClient. I tried this code:

JSFClientServerSession session = goTo("/pages/users.jsf");

WebTable usersTable = session.getClient().getWebResponse().getTableWithID("listForm:userListTable");
TableRow firstUserRow = usersTable.getRows()[1];

HashMap<String, String> params = extractParams(firstUserRow.getAttribute("onclick"));

PostMethodWebRequest request = new WebRequestFactory(session.getClient()).buildRequest("listForm");
for (Map.Entry<String, String> entry : params.entrySet()) {
 request.setParameter(entry.getKey(), entry.getValue());
}

session.getAjaxClient().ajaxSubmit("listForm", params);

It extracts parameters from javascript event onclick and tries to make a ajax request. The problem is that it server logs this request is being made (that's good) but test fails. Exception

java.lang.NullPointerException

at ui.test.UserListTest.testShowDetails(UserListTest.java:92)

I search the web and it seems to be Xalan problem (I'm on JBoss 4.2). Does anyone knows a workaround? Or how to emulate click on table row differently?

Cheers :)

You might want to try out the new JSFUnit from subversion. It replaces the client with one that is based on HtmlUnit instead of HttpUnit. Though this code is still a few weeks from beta, at least you won't see the NPE you are running into now.

If you look at the online demo, you will see that RichDataFilterSlider has an example JSFUnit test and that example uses rich:dataTable. Click on the source link to see the old version of the test.
http://jsfunit.demo.jboss.com/jboss-jsfunit-examples-richfaces/richfaces/dataFilterSlider.jsf

The new version of the test is below:

Hope that helps. I won't be around as much for the next few days, but I'll be back on this forum regularly again on Wednesday.

With JSFUnit from the trunk it works and no errors are generated. Thanks a lot.

Just in case anybody had a problem. One should use this classes:

import org.jboss.jsfunit.jsfsession.JSFClientSession;
import org.jboss.jsfunit.jsfsession.JSFServerSession;

and not from org.jboss.jsfunit.facade.
