Hello,
First of all, thank you for SmartGWT! It's been a slick and flexible way for me to write pretty advanced and good-looking GUIs!
I'm posting now with a problem I've encountered in Dev Mode when trying to draw a TreeGrid that is bound to a DataSource. I have my own client-only DataSource to which I addData() by creating TreeNode objects and defining their property values. (For my project, I want the root of the Tree to be some value that is less than 1 or is not an Integer; I would prefer a null value for convenience.)
As it is I get the "Loading Data..." message in the TreeGrid and an unspecific error message on the stderr console of my IDE: "Uncaught JavaScript exception [Exception thrown and not caught] in http://localhost:8080/Ticketer/gwt/Workbench/hosted.html?Workbench, line 281". The sample code posted below renders fine if I compile and run without Dev Mode. It also works in Dev Mode if I refactor the TreeGrid/TreeGridField/TreeNode objects to ListGrid/ListGridField/ListGridRecord.
Am I missing something? Have I done something stupid? Thanks for taking a look!

Code:
public class TreeGridDatasourceTest extends VLayout { public TreeGridDatasourceTest() { TreeGrid grid = new TreeGrid(); grid.setSize("125px", "100px"); grid.setLeaveScrollbarGap(false); TreeGridField idField = new TreeGridField("TicketID", "Ticket ID"); TreeGridField parentField = new TreeGridField("ParentID", "Parent ID"); grid.setFields(idField, parentField); MyDS ticketDS = new MyDS("tickets"); TreeNode node1 = new TreeNode(); node1.setAttribute("TicketID", 1); /*Integer nullParent = null; node1.setAttribute("ParentID", nullParent);*/ TreeNode node2 = new TreeNode(); node2.setAttribute("TicketID", 2); node2.setAttribute("ParentID", 1); ticketDS.addData(node1); ticketDS.addData(node2); grid.setDataSource(ticketDS); grid.setAutoFetchData(true); this.addMember(grid); } private class MyDS extends DataSource { public MyDS(String id) { super(id); setClientOnly(true); DataSourceIntegerField ticketId = new DataSourceIntegerField("TicketID", "Ticket ID"); ticketId.setPrimaryKey(true); DataSourceIntegerField parentId = new DataSourceIntegerField("ParentID", "Parent ID"); parentId.setForeignKey("TicketID"); setFields(ticketId, parentId); } } }
