People Picker to add users to SharePoint 2010 group - Namespace prefix 'xsd' is not defined

Hi All,

We have recently migrated from SharePoint 2007 to SharePoint 2010. Upon trying to add users to SharePoint group, we got the below error:

System.InvalidOperationException: Namespace prefix 'xsd' is not defined.    at System.Xml.Serialization.XmlSerializationReader.ToXmlQualifiedName(String value, Boolean decodeName)     at Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationReaderDictionaryEntryArray.Read1_Object(Boolean isNullable, Boolean checkType)     at Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationReaderDictionaryEntryArray.Read2_DictionaryEntry(Boolean checkType)     at Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationReaderDictionaryEntryArray.Read3_ArrayOfDictionaryEntry()

The problem here is we have a known issue with people picker not working properly in IE9..

Possible Resolutions:

Solution 1 (Temporary Solution)

Change the Document Mode to IE-8 using IE - developer toolbar as shown below

Solution 2 (Permanent Solution)

In System master page, change the content attribute in meta tag from IE-9 to IE-8 as shown below.

<meta http-equiv="X-UA-Compatible" content="IE=8"/>

Hope this helps some one. Thanks !!!

ABCpdf stopped working after IE9 is installed

Hi All,

We use ABCPDF to generate PDF out of a SharePoint data. The version we use is 8.0.0.5. Till now, everything worked fine and suddenly, ABCPDF stopped working with the below error message:

"ABCpdf could not initiate MSHtml engine for this version of Internet Explorer installed."

The only change done to the server was that IE9 is installed. According to the WebSuperGoo support team, ABCPDF versions below 8.1 do not support IE9. The below is the explanation:

Using IE9 on the same system as older ABCpdf versions may cause this error message. The current release - ABCpdf 8.1 - is fully compatible with IE9 and also provides a new Gecko-based HTML engine.

When converting HTML to PDF, ABCpdf uses the MSHTML component installed with Internet Explorer as the first stage of the process. The issue when using older ABCpdf versions is related to a set of problems Microsoft introduced in IE9. We (and other developers) reported these issues to Microsoft in September 2010 but unfortunately they have not been fixed.

Unfortunately with the official release of IE9 Microsoft released new documentation which says the IHTMLElementRender::DrawToDC function that was required has been deprecated. This is especially unfortunate given that there is no replacement for this function.

Given that Microsoft appears to be unwilling to support these interfaces we would strongly recommend that on new deployments you consider a move to the new Gecko-based HTML engine available in ABCpdf 8. It is just one line of code to select the Gecko rendering engine (see the Doc.HtmlOptions.Engine property).

WorkAround:

Change the Rendering Engine from MSHtml to Gecko by using the below code:

Doc theDoc = new Doc();
theDoc.HtmlOptions.Engine = EngineType.Gecko;

After this issue is resolved, we got one more error which says "The RPC server is unavailable"
