inmethod datagrid and row additions and filtering

[Deren]

What is the best way to handle an IDataSource backed by a list that might change in total size or in contents (add/remove items and filter items)?  I have seen cases where the most recently added item is missing (corrected after a refresh), where only the last item is displayed (e.g., one row displayed but 1-8 of 8 in the footer -- also corrected after a refresh), and where no items are displayed after a page refresh.

 

Thanks.

I ended up making the following changes to the inmethod datagrid in order to get the correct behavior:

AbstractPageableView.java:

+      public void reset() {
+           realItemCount = UNKOWN_COUNT;
+           maxFirstItemReached = 0;
+           queryResult = null;
+           cachedPageCount = -1;
+           currentPageFirstItem = 0;
+      }

 

DataGridBody.java:

+      void reset() {
+            getData().reset();
+      }
 

DataGrid.java:

+     protected void onModelChanged() {
+         super.onModelChanged();
+         getBody().reset();
+    }
