I have a form that is used to filter tasks (the page default is "everything"; you can type in either "Application" or "Customer" fields and the autosuggest/autofill starts to populate the respective field.)
The submit button prevents the default form submit and does the submit via AJaX. So far, this is working quite nicely, IF the user clicks on or highlights a suggestion.
However, should the user hit the enter key without highlighting one of the suggestions, the selections disappear and the field is left with just the letters that the user has typed, thus far, and submits the form (bypassing the preventDefault() command), and the next thing I see is the whole page is replaced by just the form.
If I could figure it out, I suppose I could put an event handler that will ignore the Enter key; but this is the first time I've used ui.combobox, and I'm not sure what to do.
