DataSourceEnumField foreign key to itself

[levi]

Hi,

I've got a list of values and an extra enum field which holds all those values again (to create a hierarchy).

So columns are: id, role, mainrole (another role id)


The only thing I need to do for the mainrole in SmartGWT in the definition of the DataSource is -sweet-:

		field = new DataSourceEnumField();
		field.setForeignKey(this.getID()+".id");
		addField(field);

After adding a record, the new value can be seen chosen from the enum too without any code necessary, which is excellent.


The problem is that the filter on the grid never sees the values (as they are loaded after the grid is drawn),
and when I actually choose an enum, the grid always says "not a valid option" on that column.

I also don't want to see the IDs, but the role text field. I tried using a valueMap instead and built it during fetch, but it gave me the same problem: "not a valid option".


What would be the best way into creating this? If I really need to get the values before drawing the grid, then I would need to destroy and re-draw the grid every time a user adds a new role.
