this.props.dispatch 没有正常触发

ChrisFan commented 8 years ago

有两个组件：分别为 DataFlowPanel\ModelGroup，项目是一个 dva project

DataFlowPanel 与 ModelGroup 关系

<DataFlowPaper
  connections={connections}
  onActiveNodesChange={this.onActiveNodesChange}
>
  <StateGroup coordinates={coordinates.state} />
  <ModelGroup coordinates={coordinates.model} models={models.data} />
  <ComponentGroup coordinates={coordinates.component} components={routeComponents} />
</DataFlowPaper>

DataFlowPaper 具体实现：

drawPaper() {
  if (!this.Paper) {
    this.Paper = createContainer({
      width: 1000,
      height: 1000,
    })(Paper);
  }
  return this.Paper;
}
...
const DataFlowPaper = this.drawPaper();

ModelGroup 实现：

class ModelGroup extends React.Component {
  drawLabel() {
    const { coordinates } = this.props;
    if (!this.label) {
      this.label = createNode(
        () => ({
          getNodeData: () => ({
            id: 'ModelGroup.Label',
            x: coordinates.x,
            y: coordinates.y,
          }),
          canDrag: () => false,
          canSelect: () => false,
        })
      )(Label);
    }
    return this.label;
  }
  drawModelList() {
    const { coordinates, models } = this.props;
    return models.map((m, i) => {
      const data = {
        id: m.id,
        x: coordinates.x,
        y: coordinates.y + 36 + i * 35,
      };
      return (
        <ModelNode key={m.id} data={data} showActionFlow={this.showActionFlow}>
          {m.namespace}
        </ModelNode>
      );
    });
  }
  render() {
    const { coordinates } = this.props;
    if (!coordinates) return null;

    const ModelLabel = this.drawLabel();
    return (
      <div>
        <ModelLabel>MODELS</ModelLabel>
        { this.drawModelList() }
      </div>
    );
  }
}

ModelGroup.propTypes = {
  coordinates: PropTypes.object,
  models: PropTypes.array,
};
export default connect(({ dataflow }) => ({ dataflow }))(ModelGroup);

问题是，在 ModelGroup 中通过 this.props.dispatch 触发 action 不成功；但是在 DataFlowPanel 中可以

哪个位置触发不成功？

在 Paper children 中的组件：ModelGroup

this.props.dispatch 没有正常触发 #6
