[SharePoint 2010 – Developpement] Create a Content Query Webpart in Site Definition (onet.xml), with dynamic site Url

I wanted to create a webtemplate with content query webpart in pages. Those webpart had to have the current site url. So I used the hack “~Site” in the properties of the webpart
Here are the step for it :

Step 1 : Create the Content query WebPArt Graphically

Create your webpart, and edit its properties (filter on content type, on column etc)

STEP 2:  Export the WebPart

From the page, export the webpart

STEP 3 : Modify the generated file exported .webpart

Modification 1 :
<property name=”ListGuid” type=”string”>d2d…
replace it by =>
<property name=”ListGuid” type=”string”/>

Modification 2 :
replace the property Weburl by
<property name=”WebUrl” type=”string”>~Site</property>

Step 4 : Integrate the CQWP in your onet.xml

   1: <AllUsersWebPart

   2:           WebPartZoneID="Left"

   3:           WebPartOrder="1">

   4:           [CDATA[<webParts><webPart xmlns="http://schemas.microsoft.com/WebPart/v3%22>

   5:     <metaData>

   6:       <type name="Microsoft.SharePoint.Publishing.WebControls.ContentByQueryWebPart, Microsoft.SharePoint.Publishing, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />

   7:       <importErrorMessage>Cannot import this Web Part.importErrorMessage>

   8:     metaData>

   9:     <data>………..data>

  10:   webPart>

  11: webParts>]]>

  12:         AllUsersWebPart>

Deploy the solution and it will work
