+Summary: Fails on PostBack when HtmlTextArea is located in Dynamically Loaded Control
+Description of Problem:
+I get the following error when I postback to a form that contains a UserControl that has been 
+dynamically loaded via LoadControl, and that UserControl contains an HtmlTextArea control (or 
+asp:TextBox that creates an HtmlTextArea internally).
+System.NullReferenceException: Object reference not set to an instance of an object
+  at System.Web.UI.HtmlControls.HtmlTextArea.DefaultLoadPostData (System.String postDataKey, 
+System.Collections.Specialized.NameValueCollection postCollection) [0x00000] 
+  at System.Web.UI.HtmlControls.HtmlTextArea.LoadPostData (System.String postDataKey, 
+System.Collections.Specialized.NameValueCollection postCollection) [0x00000] 
+  at 
+(System.String postDataKey, System.Collections.Specialized.NameValueCollection postCollection) 
+  at System.Web.UI.Page.ProcessPostData (System.Collections.Specialized.NameValueCollection 
+data, Boolean second) [0x00000] 
+  at System.Web.UI.Page.InternalProcessRequest () [0x00000] 
+  at System.Web.UI.Page.ProcessRequest (System.Web.HttpContext context) [0x00000] 
+This does not occur with other controls.  When a dynamically loaded UserControl not containing 
+an HtmlTextArea is posted back, everything works as expected.
+Steps to reproduce the problem:
+1. Create a UserControl that contains an HtmlTextArea or multi-line TextBox 
+2. Dynamically load into a form using LoadControl
+3. Postback form
+Actual Results:
+Exception noted above.
+Expected Results:
+Somewhat obvious.
+How often does this happen? 
+Every time a dynamically loaded control containing the HtmlTextArea is posted back.
+Additional Information:
+Consistent in every version of Mono since 1.2.  Does not occur in first release of 1.2 or prior 
+versions of Mono.  Occurs in both XSP and XSP2.
