Children divs unable to access Angular scope

This section is from my controller:

mbpMod.controller("bookController", function($scope,api) {   
    ...
    $scope.bookTable=new BookTable();
    $scope.bookLabel="Book";
    ...
}

On the HTML page, it functions properly with this code:

<md-tab>
        <md-tab-label class="mbpPanel">Book</md-tab-label>   
        <md-tab-body>       
         <div flex ag-grid="bookTable.table" class="ag-mbp lowtable" ng-controller="bookController"></div>
    </md-tab-body> 
</md-tab> 

However, it encounters issues when formatted like this:

<md-tab>
    <div ng-controller="bookController">
        <md-tab-label class="mbpPanel">{{bookLabel}}</md-tab-label>   
        <md-tab-body>       
             <div flex ag-grid="bookTable.table" class="ag-mbp lowtable" ></div>                
        </md-tab-body> 
    </div> 
</md-tab>

Inserting the ng-controller directive in the md-tab tag causes a conflict due to duplicated directives.

Do you have any suggestions?

Answer №1

Utilizing the md-tab-directive allows for specifying tab information and customizing its appearance.

During compilation of the directive, the controller associated with the md-tabdirective is activated. By examining the corresponding source code on Github, it becomes apparent that the controller scans the direct descendants of the md-tab directive to fetch the contents of md-tab-label and md-tab-body.

In a functional example provided, both md-tab-label and md-tab-body are nested within md-tab. Conversely, in a faulty instance, only a div element is contained within md-tab, resulting in the controller's inability to locate a label or body for the tab.

By relocating the ng-controller declaration outside the scope of the md-tab definition, the issue should be resolved.
