    Hello, I have a collection of objects which implemepts IEditableCollectionView. I bind this collection to dataSource of DataGrid (Actually XamGrid) In my AddNew i prepare the item i want to add to the collection . Than i enter the indexer of the object i am adding and setting it's attributes (i have a dynamic DataGrid columns) Than in my CommitAdd i add the prepared item to the collection. I do it like this: private Boolean _isAdding = false; public object AddNew() { _isAdding = true; _attributeRow = new FilterSetDefinitionAttributeRowViewModel() {ParentViewModel = _parent}; return _attributeRow; } private FilterSetDefinitionAttributeRowViewModel _attributeRow; public void CommitNew() { Add(_attributeRow); _isAdding = false; } public void CancelNew() { _isAdding = false; } But after it's complete i get an exception saying "Parameter count mismatch" from mscorlib Maybe i miss something? i even don't enter the CommitNew method
