Yes, I added the table to the provider as a data display. I was not
invoking dataProvider.refresh() as I thought invoking
dataProvider.setList(myList) would update all displays. In fact, my
table is indeed updated. After I call setList on the provider, I can
query the table and see the updates have occurred (and popup the same
table in a Popup shows the updated table). The problem is, the table
was originally placed in a SplitLayoutPanel, inside a DockLayoutPanel,
etc., and that is not being updated.
I know the table is correct because I can query and put it in a popup.
I discovered that trying to figure out why the updated info was not
being displayed. If I wait until the table is updated and then place
it in the same panel hierarchy, it displays correctly. But updates are
not displayed.
Here's a small snippet with trace code where the update occurs (trace
information shows correct update):
public void setSelectedFoodGroup(FdGroupEntity foodGroup,
List<FoodDesEntity> foods) {
logger.entering(NutritionDataView.class,
"setSelectedFoodGroup");
logger.info("Adding food list of size: " + foods.size());
if (!dataProvider.getDataDisplays().contains(table)) {
logger.info("Adding display");
dataProvider.addDataDisplay(table);
}
dataProvider.setList(foods);
table.setPageSize(foods.size());
dataProvider.refresh();
logger.info(table.getRowElement(5).getInnerHTML());
logger.info("page start=" + table.getPageStart());
// PopupPanel popupPanel = new PopupPanel(true);
// popupPanel.setWidget(this);
// popupPanel.show();
}
