Body
I'm using HtmlUnit to interact with a web page that interacts with the server via Ajax. Soon after the Ajax code starts, HtmlUnit produces these two log messages: <pre>WARNING: Ignoring XMLHttpRequest.setRequestHeader for Content-length: it is a restricted header Mar 3, 2011 3:32:47 PM com.gargoylesoftware.htmlunit.javascript.host.xml.XMLHttpRequest jsxFunction_setRequestHeader WARNING: Ignoring XMLHttpRequest.setRequestHeader for Connection: it is a restricted header Mar 3, 2011 3:32:47 PM com.gargoylesoftware.htmlunit.javascript.host.xml.XMLHttpRequest jsxGet_status</pre> ...Followed by this message, repeated six times: <pre>SEVERE: XMLHttpRequest.status was retrieved before the response was available. Mar 3, 2011 3:32:47 PM com.gargoylesoftware.htmlunit.javascript.host.xml.XMLHttpRequest jsxGet_status</pre> I can't figure out how to turn these messages off. Trawling through the code shows that they're produced by direct calls to a logger, not via a handler object that I could provide a do-nothing implementation for, as I already do for CSS errors. The <a href="http://htmlunit.sourceforge.net/logging.html">HtmlUnit logging page</a> indicates that adding this code should work: <pre><code>System.getProperties().put("org.apache.commons.logging.simplelog.defaultlog", "fatal"); </code></pre> ...but it has no effect. I also tried adding the following option where I invoke java: <pre><code>-Dorg.apache.commons.logging.simplelog.defaultlog=fatal </code></pre> ...but that also has no effect. I guess I could redirect stderr to /dev/null while this code is executing, but are any less hacky solutions available?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
