SmartGWT Warning when destroying DrawItem

[sderouchie]

I am trying to get rid of any warnings produced by SmartGWT in our product in order to ensure we are using SmartGWT as intended.

One warning I can't seem to resolve is when using the Drawing API (e.g. DrawLine), destroying the object gives the following:
"DrawItem not yet drawn - exiting erase()"

The line is drawn: it is displayed in the window.

I can reproduce the issue if I use the code from this example:
http://www.smartclient.com/smartgwt/showcase/#lines_and_arrowheads

Here is the information for my development environment:
Isomorphic SmartClient Framework (v8.2p_2012-08-08/PowerEdition Deployment 2012-08-08)

FireFox 14.0.1 (may not be limited to this browser)

Here are the log messages from the console:

15:48:20.853:MUP7:INFO:destroys:isc_DrawPane_0:destroy()
15:48:20.864:MUP7:WARN:DrawLine:isc_DrawLine_1:DrawItem not yet drawn - exiting erase()

[DynamicForm ID:dynamicForm]
104 drawn length (policyLength: 104) (inherent size)
300 drawn breadth (explicit size)

Please let me know if any more information is needed.

I'm still having this issue. Any suggestions?
