Original report by Brandon M (Bitbucket: bmagliano, GitHub: Unknown).
If I randomly click around in cells, resize them, change values continuously I am able to make the cells shift and remain that way until the application is closed. This also throws some nullpointerexceptions. I have tried to narrow down the behavior that causes this but I am unable. I essentially keep clicking, change cell sizes and throw a cell value change here and there. Once it goes in start exceptioning there is no going back. I have been able to recreate this three times with the following code.
controlsfx 8.40.9 maven java 8_45
#!java
TabPane tabPane = new TabPane();
Tab tab = new Tab("Test");
int rowCount = 15;
int columnCount = 10;
GridBase grid = new GridBase(rowCount, columnCount);
ObservableList<observablelist>> rows = FXCollections.observableArrayList();
for (int row = 0; row < grid.getRowCount(); ++row) {
final ObservableList<spreadsheetcell> list = FXCollections.observableArrayList();
for (int column = 0; column < grid.getColumnCount(); ++column) {
list.add(SpreadsheetCellType.STRING.createCell(row, column, 1, 1,"value"));
}
rows.add(list);
}
grid.setRows(rows);
SpreadsheetView spv = new SpreadsheetView(grid);
tab.setContent(spv);
tabPane.getTabs().add(tab);
AnchorPane root = new AnchorPane();
root.getChildren().add(tabPane);
Scene scene = new Scene(root, 1024, 768);
stage.setTitle("Hello SpreadsheetView!");
stage.setScene(scene);
stage.show();
</spreadsheetcell></observablelist>
