expand-level not working when tree-data loaded dynamically

[Hesesses]

html:

<tree-grid tree-data="settings.documentsTreeDdata" tree-control="my_tree" col-defs="col_defs" expand-on="expanding_property" on-select="my_tree_handler(branch)" expand-level="5" icon-leaf= "glyphicon glyphicon-globe"></tree-grid>

JS:

function initTreeView() {

        var tree;

        var rawTreeData = [

        var myTreeData = getTree(rawTreeData, 'DemographicId', 'ParentId');

        $scope.settings.documentsTreeData = myTreeData;    
        $scope.my_tree = tree = {};
        $scope.expanding_property = "Name";
        $scope.col_defs.length = 0;

        for (var i = 0; i < rootIds.length; i++) {
            tree.push(treeObjs[rootIds[i]]);
        };

        return tree;
    }

$scope.col_defs = [];

And later call

initTreeView()

tree-grid only displays the three elements (United States of America, India, Bangladesh) not expanded

[melozzo]

this is a show stopper for the application I am working on

[esinek]

I haven't done a lot of work on this, so YMMV, but this seemed to work in my initial tests.

In the function _add_branch_tolist, look for this statement: _return b.expanded = b.level < expandlevel; and replace with this _return b.expanded = b.level <= expandlevel;

Let me know if that works for you (or submit the PR yourself :-))

[TrueDub]

Are you sure you're looking at the latest version of the directive? That line doesn't appear in that function.

[TrueDub]

I have a solution for this issue, but it has a caveat - you can never collapse the tree to less than the expand-level. I'm not sure this will meet the need here, so all comments welcome, before I submit a pull request.

[TrueDub]

The fix for this is in release 0.4.0 of this directive - closing now.
