Dojo 1.5.0 Charting Legend missing

Question

I just upgraded from Dojo 1.4.3 to 1.5.0 and noticed that my legend is now missing. Anyone else have this problem??

I keep receiving the following error:

o is undefined in dojo.js line 73

This error occurs when

chart1.render(); //Graph shows but error causes the rest of the code in that javascript function to not execute (So, not legend because it's created after chart1.render(); line.

executes. Works perfect in release 1.4.3.

Found the problem..It seems like a bug but not 100% sure...Here is how to recreate it using the Dojo Nightly Charting Tests code and dojo version 1.5.0 (Any web browser):

NOTE: This error occurs when adding a series to plot "other" and calling chart1.render(); more than once. If chart1.render(); is only called once, no error and everything works as it should. See addSeries for "Series B"...Remove plot: "other" from "Series B" and everything works OK even if chart1.render() is called twice. This problem can also be recreated by just removing "markers: true" from the "default" addPlot and calling char1.render(); twice.

Warning: The HTML below in the code section isn't displaying 100% correctly but all the javascript code is present to recreate this problem easily.

Eugene: Thanks for the link to the testing page, that helped out. Also, should I file a bug report on this??

Does charting tests work for you? Go to Dojo Nightly Charting Tests and select a test, which uses Tooltips, e.g., test_event2d.html. If it works for you, see what is different in your setup. If you found the difference, and it is related to Dojo, please file a bug. Don't forget to mention a browser you use, and attach a minimalistic test case as a file.
