[Htmlunit-user] cannot read html updated source

[Christoff, K. <kch...@no...>]

Hello,

I'm trying to automate a cloudera installation by using htmlunit-2.19.
I've downloaded cloudera-manager-installer.bin from cloudera.  After
executing it, a cloudera manager installer web site is available at
http://localhost:7180.  I'm trying to navigate this web site and supply
inputs using htmlunit-2.19 to complete my installation.

I can use htmlunit to login and navigate to the page where I can enter the
hostnames of what will become my hadoop cluster.  After setting a textArea
on this page with my comma-separated list of hostnames, I find and click a
"Search" button on the page.  The page, I believe, executes some javascript
to go out and find these hosts.  After finding them, the page is updated
with a list of the nodes.  At this point, a previously unavailable
"Continue" button on the page becomes available.  I'd like to click it to
move to the next page and continue my installation.

However, my java program never sees the updated list of nodes and I cannot
move forward.  I know that htmlunit normally does not wait for javascript
to finish, so I've taken steps to allow for that.  As you'll see in my
attached code, I've:

webClient.setAjaxController(new NicelyResynchronizingAjaxController());

and after clicking the "Search" button:

webClient.waitForBackgroundJavaScript(10000);

but I've not been successful.

How can I capture the page updates and continue my installation?

thank you,
Kyle
