ComboBox - Validate so default value is not selected

One of the things that I've been trying to get to work in XPages is getting validation to reject the default value of a combobox. Well, this morning I sat down and decided to get it done. I've used other methods to get around this until now, but this seems to do it.

I have a combobox with "--Select--" as the default value. If that value is still there on submission, I want a display error control to execute. To do this, I think you need to have "--Select--" as the itemValue as well as the itemLabel, but I'm not sure, as I habitually use both anyway.

Add a validateContraint, and use the RegEx "^((?!--Select--).)*$" , I got this from this StackOverflow Post. So on submission, if a value hasn't been selected (errm, sorry) no dice.

I tested on a combobox that needed the user to select the month, the entire element is below.

There may be a better way, but having this will be a relief for me.

Cheers,
Brian

Declan Lynch provided a Signature Capture Control on OpenNTF some time ago. I had downloaded and played with it a bit, but hadn't had a production use for it, but it worked just like it said on the tin - drop it in and use it. Recently I was asked to come up with a way to let people sign into an event using tablets, so a perfect opportunity to pull it out. It was a breeze to add it to the sign-in portion, we display a page on a mobile device and the user can sign in on the canvas. That was the
