Hi,

I found the similar issue with same error message as

"Selenium.SeleniumException : ERROR: Couldn't access document.body. Is this HTML page fully loaded?"

This error is not shown everytime for a single test suite execution. Instead it appears for different suites, and on running the failed suites again, these are passed with error shown for some other suites.

The details of the environment used is as:
OS: Win XP (Pro) Service Pack #2
Web Application under test developed in .net.

For Selenium Automation Testbed we are using following:
MS Visual Studio Express Edition C# 2005/2008.
NUnit 2.4.6
selenium-remote-control-1.0-beta-1

The error details are as:

Are you testing an AJAX based web application ?

If yes, you have to wait until a certain element is present in your page using the Wait object (see the javadoc of Selenium, or the equivalent if you are not using java). You have to choose an element in your DOM tree that you are sure that if present the entire page is loaded.

You can also reduce the speed of selenium by using the Selenium.setSpeed method. It may help.

What worked for me was to change:

click(...)

waitForPopUp (summaryWindow)

assertTextPresent (abc)

to

click(...)

waitForPopUp (summaryWindow)

waitForTextPresent (abc)

assertTextPresent (abc)

I'm experiencing the same problem with 0.9.2 and 1.0-beta-1.   Has anyone figured out a workaround yet?
