私はJavaScriptでこれをやっています:
function doClick() {
var theValue = document.getElementById("theForm:theField").value;
var theLength = theValue.length;
if( theLength <= 3 ) --> Error
{
alert('Character length too small.');
}
}
そしてthefield
JSFコンポーネントです:
<h:form id="theForm">
<h:commandButton id="theField" action="#{theBean.doFunctionA}" onclick="doClick()"/>
これを IE でレンダリングすると、次のエラーが表示されます。
Caused by: javax.faces.view.facelets.FaceletException: Error Parsing /viewMetadata/pages/thePage.xhtml: Error Traced[line: 66] The content of elements must consist of well-formed character data or markup.

エラー行を次のように置き換えると:
if( theLength == '3' || theLength == '2' || theLength == '1')
その後、すべてが正常に機能しています。私は本当に何が起こっているのか本当に理解していませんか?
