Error using custom tiles - 4.1p 2014-05-19

4.1p 2014-05-19

Hi guys,

I tried a slightly different (not data source bound) flavor of custom tiles using the showcase example. When I add my custom tiles to the grid I get an exception.

Do I need to implement something like SimpleTile's getRecord to make it work?

The javadoc says any child of Canvas is allowed so here's a simplified example (using Label) that produces the same error:

TileGrid grid = new TileGrid();
grid.setTileConstructor(Label.class.getName());
grid.setTiles(new Label("test"), new Label("test2"));
addMember(grid );

Exception in dev mode (only tried in dev mode). One copy of the exception is thrown per Label added to the grid:

See docs for Reflection.

Never Mind!

Don't know what possessed me to use TileGrid. TileLayout worked fine. :)

Oops that right I would have needed to initialize that class for reflection. Thanks.
