Using UI hash key in an events hash
backbone.js, marionette
Solution
Okay, problem solved after you showed version.
This feature, parsing @ui. syntax within the events and triggers hash, is recently added in 1.4.0 in early December. See changelog: https://github.com/marionettejs/backbone.marionette/blob/master/changelog.md
Just update your Marionette version to the latest stable(1.4.1 currently) and problem should be solved.
*I just noticed this new feature thanks to your question. I don't feel comfortable at this point before, now solved. Another evidence of helping others could also help the man himself. :)
Problem
I am using marionette version 1.2.3 and backbone version 1.1.0 Here is my UI and events hash: ``` ui:{ title : '#modelTypeTitle' }, events: { 'change @ui.title' : 'validateTitle' }, ``` This seems to match what the documentation says: "You can also use the ui hash values from within events and trigger keys using the '@ui.elementName'" To clarify I want to know why what I am trying above does not work. but the following works fine: ``` events: { 'change #modelTypeTitle' : 'validateTitle' }, ```
