Body
I need to display an unknown quantity of tabs each with an unknown quantity of graphs (Google Visualizations). I have created "Tab" and "Graph" classes and Tab contains an ArrayList. TabWrappers extends FlexTable and is currently empty. It's a place holder at the moment, but the behavior does not change if I use FlexTable rather than TabWrapper. The code below, minus the section that adds Tab2 works perfectly for creating 1 tab populated with graphs. When adding the 2nd tab both tabs are displayed and named correctly but neither have graphs. <pre><code> public class SomeClass { ... DataTable data = response.getDataTable(); DataView result; Options options = createOptions(); ArrayList<Tab> displayTab = new ArrayList<Tab>(); Tab t; ArrayList<Graph> graphList = new ArrayList<Graph>(); Graph g; t = new Tab(); g = new Graph(); result = DataView.create(data); result.setRows(new int[]{0, 2, 4, 6}); g.setGraphType(new PieChart(result, options)); graphList.add(g); g = new Graph(); result = DataView.create(data); result.setRows(new int[]{1, 3, 5, 7}); g.setGraphType(new PieChart(result, options)); graphList.add(g); g = new Graph(); result = DataView.create(data); g.setGraphType(new PieChart(result, options)); graphList.add(g); t.setTabName("Tab1"); t.setGraphs(graphList); displayTab.add(t); // Add a 2nd tab t = new Tab(); t.setTabName("Tab2"); t.setGraphs(graphList); displayTab.add(t); TabWrapper tabWrapper; for (Tab tX : displayTab){ int row = 0, col = 0, maxCol = 2; tabWrapper = new TabWrapper(); for (Graph gX : tX.getGraphs()) { col = tX.getGraphs().indexOf(gX) - (row * maxCol); tabWrapper.setWidget(row, col, gX.getGraphType().asWidget()); if (++col == maxCol) { row++; } } tabPanel.add(tabWrapper, tX.getTabName()); } ... } </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
