Here is the form I used:

 client.click("commandButton");

1. Re: Wrapped java.lang.RuntimeException: Could not retrieve X

There appears to be a problem in this method (HtmlUnit) in com.gargoylesoftware.htmlunit.javascript.host.EventHandler

public EventHandler(final DomNode node, final String eventName, final String jsSnippet) { node_ = node; eventName_ = eventName; final String functionSignature; if (node.getPage().getEnclosingWindow().getWebClient().getBrowserVersion().isIE()) { functionSignature = "function()"; } else { functionSignature = "function(event)"; } jsSnippet_ = functionSignature + " {" + jsSnippet + "\n}"; }

For some reason the node is a com.gargoylesoftware.htmlunit.html.HtmlElement which forces a cast to HtmlPage in the getPage() method.

If I comment out the browser check (Since I know the browser isn't set to IE), my test code works fine, but that doesn't explain what causes this.

Looks like an HtmlUnit bug.

The above doesn't seem to be an isolated case, I seem to encounter many cases where an XmlPage (likely the response from an ajax call) is mistakenly used for the current page (expecting an HtmlPage). It seems most common when there is a reRender="" attribute defined on a control.

Thanks for the info. I'm looking at it now. Hopefully, it's a JSFUnit problem. That will be easier to fix.

I don't know if this is related, but I have a case where a datatable with
links for each record. This table is re-rendered from an ajax call. Calling
client.getElement() for the ID of the links (after the ajax update) gives me
the expected "matches more than one JSF component ID" exception and
lists the links that were there prior to the ajax call - not what should be
there now. Calling client.getContentPage() and then dumping the xml
(HtmlPage.asXml()) does display the updated page.

BTW, what's up with the page width on this discussion?

ssilvert Jun 17, 2008 5:55 PM (in response to bgregory)
The stack trace had a long line in it, which made our forum increase the width to its crazy size.

Your datatable problem could be related. I have to distinguish between an a4j request that changed the view and one that didn't (like a resource request). I need to take a closer look at that.

BTW, HtmlUnit fixed an earlier problem with IE, so you are no longer required to use Firefox emulation. If you use the latest HtmlUnit code you can work around your original problem like this:

WebClientSpec wcSpec = new WebClientSpec("/refresh.faces", BrowserVersion.INTERNET_EXPLORER_6_0); JSFSession jsfSession = new JSFSession(wcSpec); JSFClientSession client = jsfSession.getJSFClientSession(); client.click("commandButton");

Maybe you can try that and see if your datatable problem goes away too.

Plain old click is now working:

<h:selectOneMenu id="Weekdays">
 <f:selectItem id="selectMonday" itemValue="Monday"/>
 <f:selectItem id="selectTuesday" itemValue="Tuesday"/>
 <f:selectItem id="selectWednesday" itemValue="Wednesday"/>
 <f:selectItem id="selectThursday" itemValue="Thursday"/>
 <f:selectItem id="selectFriday" itemValue="Friday"/>
 <f:selectItem id="selectSaturday" itemValue="Saturday"/>
 </h:selectManyListbox>

JSFSession jsfSession = new JSFSession("/indexWithExtraComponents.faces");
 JSFClientSession client = jsfSession.getJSFClientSession();
 JSFServerSession server = jsfSession.getJSFServerSession();

 client.click("selectMonday");
 client.click("selectWednesday");
 client.click("selectFriday");
 client.click("submit_button");

If you have a use case, I'll be glad to put it back though. Also, I've only tried it with <h:selectManyListbox>, but it should work the same for <h:selectOneMenu>.

Follow up from prior comment:

I built the latest HtmlUnit/JSFUnit from just now (7pm EST) and ran my simple test cases. Using the IE6 browser def it seemed to work fine.

Unfortunately I can't run my more complicated tests because the setSelected() API call has dissapeared (see my previous comment).

TX for the progress...

Good. I'll set that back as the default so you don't always have to create a WebClientSpec.

Ok, thinking about this... Every selectItem must now have an id?
What about selectItems that aren't declared in the page?

<h:selectOneMenu id="filterSelects" value="#{backingBean.selectVal}"> <f:selectItems value="#{selectItems}"/> </h:selectOneMenu>

Do I have to change the code that generates the select items to also add IDs to them? (I'd prefer not)

I don't think you can set an ID to a SelectItem generated in code:

ssilvert Jun 17, 2008 7:45 PM (in response to bgregory)

The UIComponent backing the <f:selectItems> can still have an ID even though that ID doesn't get rendered in HTML. I can look it up on server side and find the proper component to click, which is what I do.

So for your example, you would to do the same kind of thing you do for a DataTable.

For <f:selectItems id="foo" value="#{selectItems}"/>, the id's will end up like foo:0, foo:1, foo:2 ...

For the old method, you had to know the parent component id, the value of the item, and the state you wanted to set - regardless of the current state selection. Plus with the old method, I'm not sure if the onclick event is triggered.

Using plain click() you just need to know the id of the <f:selectItems> and the position in the list.

I think that's easier and looks cleaner. But perhaps there is a case where you know the value of the item but not its position? You can always search the list yourself to find its position though. What do you think?

That being said, I haven't actually tried this with a <f:selectItems>. I'll have to give that a go.
