Doc Library List View Row Checkbox Unable to Select or Check

Question

I have code behind that adds webparts to a page. An example of the code is show below.
# web is an SPWeb object
# wpMgr is the web part manager
# Get the list
SPList list = web.Lists["Document Library"];
# Create the list view webpart
XsltListViewWebPart lvwp = new XsltListViewWebPart()
ListId = list.ID,
Title = "Documents",
ViewGuid = list.DefaultView.ID.ToString(),
XmlDefinition = list.DefaultView.GetViewXml()
# Add the list view webpart to the page
wpMgr.AddWebPart(lvwp, "Main", 0);
Problem:
The issue we are having is only with document libraries. When we try to select the document library in the list view by selecting the checkbox, the item appears to be checked, but when you move the cursor away from the row, the checkbox is no longer selected.
This issue is found in Firefox and IE. I'm getting a js error in the core.js file's CountSelectedItems(a) function, shown below.
function CountSelectedItems(a) {
ULSrLq:;
if(a.CurrentSelectedItems==null) a.CurrentSelectedItems=0;
return a.CurrentSelectedItems}
The js error is "Unable to get property 'CurrentSelectedItems' of undefined or null reference". So I read this as the object a being null.
Workaround:
If you edit the webpart and click on "OK", it seems to refresh something and this is no longer an issue.
Solution:
I've tried the ListViewWebPart as well, but that didn't work for me either. Any advice is greatly appreciated.
Thanks

Answer 1

We experienced the exact same issue and resolved it by using the code below.
In short are we trimming the ParameterBinding from White spaces before adding the webpart. After adding the webpart we update an unimportant property and save back the changes. The strange thing is that this code used to work previously before we added the
"fixup". With this solution you can keep the Group by clause in the CAML Query.
Please mark as answer if it solves your problem.
SPLimitedWebPartManager webPartManager = web.GetLimitedWebPartManager(pageUrl, PersonalizationScope.Shared);
XsltListViewWebPart XsltWebPart = new XsltListViewWebPart();
SPList list = web.Lists[listName];
XsltWebPart.ListId = list.ID;
XsltWebPart.ViewGuid = list.Views[viewName].ID.ToString("B").ToUpperInvariant();
XsltWebPart.XslLink = XslLinkUrl;
XElement el = XElement.Parse("<root>" + XsltWebPart.ParameterBindings + "</root>");
var reader = el.CreateReader();
reader.MoveToContent();
string trimmedBindind = reader.ReadInnerXml();
XsltWebPart.ParameterBindings = trimmedBindind;
webPartManager.AddWebPart(XsltWebPart, zoneId, zoneIndex);
int wpIndex = webPartManager.WebParts.IndexOf(XsltWebPart);
var xwp = (Microsoft.SharePoint.WebPartPages.XsltListViewWebPart) webPartManager.WebParts[wpIndex];
xwp.ExportMode = WebPartExportMode.All;
webPartManager.SaveChanges(xwp);
