In researching a bug in my application, I have created this example that recreates the problem, which seems to be a Trinidad bug...
In order to reproduce, you should enter SPACES ONLY into the text field and submit the form. The error does not occur if you enter NOTHING or if you enter non-whitespace characters- only if the input is spaces. The error seems to be an attempt to retrieve the message label curing the render of the messages tag.. If I specify a label attribute on the inputText, it works correctly. The stacktrace is shown below the source...
