schatekar commented 8 years ago

@jdanyow Is this feature released? Apologies for a dumb question but I tried following your commit and got lost. I need to know if the following will work?

<input type="text" data-original="${name | oneTime}" value.bind="name" />

I specifically interested in the | oneTime part.

yep, the symbol for binding behaviors is & (as opposed to | for value converters).

<input type="text" data-original="${name & oneTime}" value.bind="name" />

Here's the standard way to write a one-time binding. This will be a bit more light-weight in terms of parsing and binding:

<input type="text" data-original.one-time="name" value.bind="name" />
