Toolbar buttons disabled

Prerequisites

• [x ] I have searched for similar issues in both open and closed tickets and cannot find a duplicate.
• [x ] The issue still exists against the latest master branch of yii2-tree-manager.
• [x ] This is not an usage question. I confirm having gone through and read the documentation and demos.
• [x ] This is not a general programming / coding question. (Those should be directed to the webtips Q & A forum).
• [x ] I have attempted to find the simplest possible steps to reproduce the issue.
• [ ] I have included a failing test as a pull request (Optional).

Steps to reproduce the issue

1. Installed "kartik-v/yii2-tree-manager": "dev-master"
2. Followed instructions at http://demos.krajee.com/tree-manager meticulously, copying and pasting wherever possible.
3. Displayed index.php in Chrome and Firefox browsers.

Expected behavior and actual behavior

Be able to add records using the toolbar buttons.

When I follow those steps, I see... The left panel with toolbar buttons at the bottom. All toolbar buttons are grayed (disabled). When I click them, nothing happens. The mouse cursor does not change to a hand when I hover over them. I was expecting... To be able to add a record by clicking the plus button.

In researching on Google, I found one posting wherein the person said that it would work if you added an initial record manually with: root=1, rgt=1, lft=1, lvl=0, name=SomeName. When I did that, I got this error message: Calling unknown method: backend\modules\associations\models\AssociationCategories::parents()

You can add a new record to a blank new tree in two ways.

• Option 1: First via the User interface... Only the Create New Root button (tree icon) will be enabled assuming you set allowNewRoots to true. Click this to add your first root record

• Option 2: Via tree population db methods available in creocoder/yii2-nested-sets. This can be done when you have large number of records to migrate. Check the docs for yii2-nested-sets.

Actually, with regard to Option 1, I must not have been clear when I said, "All toolbar buttons are grayed (disabled)." All, in this case, includes the tree icon. Clicking on it does nothing. I did go back in, and added 'allowNewRoots' => true, to the widget even though your instructions make no mention of it. I cleared the browser history, refreshed the page, and the tree icon still does nothing.

Read about the widget properties - allowNewRoots ... when you have NO RECORDS the first record you add is typically a tree root.

On your other points will need to understand your issue clearly - you would need to find the way to populate ONE TIME MIGRATION records in your db tables... the db inserts/updates are controlled mainly by creocoder/yii2-nested-sets extension - and there are few ways you can do that - or even write your own db migration script.

I suppose updating to version 1.1.0 would resolve blank tree root creation problems. Check and let know.
