Sticky state's view/ctrl is being reloaded when passing an object on $stateParams via the 'params' property

[aaronpikkarainen]

Greetings,

I've come across an issue when using sticky states (with deep state redirect) and passing objects as state parameters via the 'params' property of a state. The initial transition to the sticky state works well, but when you transition away and then come back to the sticky state, the view reloads and the controller re-runs (thus losing any changes made on that scope/view). This issue only happens when $stateParams contains a javascript object. Using only primitive params on the URL works fine, but there are cases when we need to pass complex objects to a state.

I took the Simple Sticky States Example (http://plnkr.co/edit/bFMLqLENmPFfCD0XCz8V?p=info) and made three small changes to it to demonstrate the issue. See my fork here...

You will see the issue when you follow these steps:

(Initial state is tabs.account.stuff)

• Enter text into the input box underneath "Here's my stuff"
• Click on the 'Survey' tab
• Click back to the 'Account' tab, which goes back to stuff because of DSR
  (the input becomes empty because the view and controller get reloaded even though it's part of a sticky/dsr group of states)

My plunker changed the following three lines of code...

• script.js - line 7
  
• script.js - lines 31 & 32
  

Thanks!

Actually, this may not be a good example because the savedSurvey state param will be a different object when coming to the state a second time (thus a reload should probably happen). I used this example for the sake of simplicity, but my actual example gets back to the sticky state via deep state redirect. I can try to modify the example.

I've now updated this issue and my plunker to be a better example using deep state redirect to return to the tabs.account.stuff state.

confirmed, yes this is a bug. sticky states does not understand typed parameters properly.
