Closing the props pane triggers "Uncaught TypeError: Cannot set property 'indexKey' of null"

[sompylasar]

The issue is that Atellier's _handleSelectComponent method assumes there's always a component to select, but in case of handling the Workspace's onCloseProperties it's null.

Line 39 in 5ad6a40

_handleSelectComponent = (component, key) => {

  _handleSelectComponent = (component, key) => {
    component.indexKey = key;
    this.setState({stagedComponent: component});
  };

Line 34 in 5ad6a40

<Workspace components={components} component={stagedComponent} onCloseProperties={this._handleSelectComponent} />

<Workspace components={components} component={stagedComponent} onCloseProperties={this._handleSelectComponent} />

return this.props.onCloseProperties && this.props.onCloseProperties(null);

  _handleCloseProperties = () => {
    return this.props.onCloseProperties && this.props.onCloseProperties(null);
  };
