Conflict between tabarray and ng-animate, caused by a known bug in angular

Bug

Hi everybody

I am using angular-schema-form with angular-schema-form-bootstrap, and I am managing my form through the tab array template provided in this package.
When using ng-animate in the Angular.JS project, an insidious problem occurs with the tabarray: the form fields within the tab are not displayed until the "add" button is clicked.

Expected behaviour

I expect them to be shown.

Actual behaviour

The form fields within the tab are not displayed until the "add" button is clicked.

Other info

As you can see editing the Plunker, the problem can be solved importing the bootstrap decorator inside "angular-schema-form". The one in this repo is bugged.
One can also disable ng-animate.

How to solve the problem

The problem as described in the Angular issue provided above, exists when one uses ng-animate and specifies more than one interpolated value in the "class" attribute of an element, in conjuction of ng-class.
In this particular situation ng-class is never evaluated.
This is the case of:
/0.2.0/src/tabarray.html
where we have

      <div class="tab-pane clearfix tab{{selected.tab}} index{{$index}}"
           sf-field-model="ng-repeat"
           ng-repeat="item in $$value$$ track by $index"
           ng-show="selected.tab === $index"
           ng-class="{active: selected.tab === $index}">

Here there are two interpolated variables inside "class" (selected.tab and $index), and ng-class is never evaluated.
So the tab-pane doesn't get the active class, that gives to it display:block over the default "display:none".
I suggest you to remove the tab{{selected.tab}} in order to solve the problem.
I'll send a pull request to do it.
After doing that everything will work fine (I have already tested it locally).

Hi Patrizio I made a comment in the PR, happy to accept, I've already been changing this whenever I find them in the decorator. Once I have alpha 3 ready I will try to push the version of bootstrap decorator compatible as well.

Sorry for not monitoring this correctly, I have added the angular-schema-form-bootstrap-lead group now.
