  1. Controller that takes the user input for the billing street
  2. send it to the Apex Controller which returns the same thing back
  3. Hides the section
  4. Shows a different section, then on click of a button shows the previous section

Result: Input fields no longer have the value, placeholder is gone, object still has correct values....It only happen when the section is hidden....

Now, i MUST be doing something fundementally wrong here cause this is such a basic scenario that if I am having this much trouble I find it hard to believe anyone can get anything done with lightning. I have spent my whole day trying to get this working but I can't.

I am leaning on you all for assistance....Otherwise, I give up.....

    Your post has drastically reduced my fledgling interest to convert our SF from Classic to Lightning. Looks like we will further delay our lightning implementation by few more months :)

  • Looks like the only way so fare is liberal use of $A.util.toggleClass(ele,'sods-hide') and replacing the renderIf with regular divs......Ugh....

  • @ZenSeeker - Don't give up. Its really cool and fun to learn (frustrating at times). It seems very fickle too but when it works it is pretty cool. Once I get it down I will prefer it to VF any day....

I was able to reproduce the issue, its seems like you are using the deprecated aura:renderIf instead of recommended aura:if.

aura:renderIf is Deprecated. Use aura:if instead.

Using aura:if will fix your issue.

  • Using auraIf yields Cannot read property 'set' of undefined for me. Will check into it more. Maybe it is the beta component being used with a depreciated component

  • @Eric I ran your code in my dev org(winter'17) using a lightning app with the above mentioned fix, the code worked fine.

  • Yea, the above is so you could reproduce it. It is not my exact code. Right now I cannot use aura:if. Caught between rock and hard place.....

    BTW This is what i LOVE about this place. Something that took me all day (learning curve) is solved within an hour by someone who has seen it before. I would have still been working on this until who knows when. A BIG Thank You!!!!
