[Htmlunit-user] focus is not a function?

[Zhenrong L. <Zhe...@sa...>]

Hey,

I have a test case which will test invalid text input: after enter an =
invalid value in the text input, then click run button, an alert will =
show up and after you click OK in the alert wondow, the focus will go =
back to the input text field for new input.=20
		....
		final HtmlPage page3 =3D (HtmlPage)input.click();
		assertEquals(handler.getCollectedAlerts().size(), 1);
		....
The test passed the assertEquals(), but I got JavaScriptException from =
console:

I checked the JavaScript and I believe the offfending code is:

  if (maxValue !=3D null && elementValue.length !=3D 0 && elementValue > =
maxValue) {
    =
alert(SAS_substituteL10N(dynamicPP_validate_msg16,elementName,maxValue,ma=
xValExclusiveMessage));
    showContent(theObject.menuItemName, theObject.menuItemName, =
theObject.contentElementName);
    window.setTimeout("formElement.focus();", 400);
    return true;
  }

But I don't have a clue how to fix this and I was wondering if someone =
can shed some light?

Thanks,
