knockout validation regex not evaluating properly

Question

I am using knockoutjs and knockout validation. I am attempting to restrict semicolons from being entered. I have tried this:

.extend({ pattern: { params: "[^;]"} });

..somehow when I enter 'pppppp' into my text input it is considered invalid. but 'eee' is valid, please help?

Thanks!

It would appear that you need to include a custom message, or not use a wrapping object.

Check out this js fiddle.

The following constructions are valid:

.extend({
    pattern: {
        params: '^[^;]*$'
        , message:"fail"
    }
})

or

extend({
    pattern: '^[^;]*$'
})

However, this results in unexpected behaviour:

.extend({
    pattern: {
        params: '^[^;]*$'
    }
})
