Selenium Exception : "return not in a function"

Question

I am writing Selenium test scripts in C#.Net and I keep bumping into this exception -

ERROR: Threw an exception: return not in function

Here is my line of code which throws the error -

string code = selenium.GetEval(
   "var win = this.browserbot.getUserWindow(); "+
   "return win.editAreaLoader.GetValue(win.loadedCodeEditorID);"
);

Can anyone please suggest why the exception is coming and what could be the best way to get a return value from GetValue javascript function?

Thanks,

Saarthak

From the selenium documentation for GetEval:

Gets the result of evaluating the specified JavaScript snippet. The snippet may have multiple lines, but only the result of the last line will be returned.

Therefore you simply need to leave off the return:

string code = selenium.GetEval(
   "var win = this.browserbot.getUserWindow(); "+
   "win.editAreaLoader.GetValue(win.loadedCodeEditorID);"
);

Got this error - ERROR: Threw an exception: win.editAreaLoader.GetValue is not a function

its an open source api. The GetEval works fine when I am not returning any value.

@saarthak - by the sounds of it GetValue is undefined. Are you sure it's not getValue?

it was getValue instead of GetValue. How stupid of me! Thanks for pointing out.
