@krunal039 about what event are you talking about? Can you provide at least an example of how reproduce it

@artf below is codepen link and i have added custom component named slider. here when you drop slider to editor and than click on it and it should open trait manager and if you change Link Title or Link to Open to blank value it throws above error.

I can't reproduce any error, but what I see wrong at the first look is how you update models

...
someModel.attributes.href = this.get("a_href");
// use
someModel.set('href', this.get("a_href"));

then you don't need $(this.el), you have already this.$el
