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();
+ }
