描述

When I use these two lines in my code then I get an error: TypeError: Cannot read property 'subgrid' of undefined

// Error!!!! grid.setValue(colPos['bob'], gridRow+1, rowData[i].bob); grid.setValue(colPos['pi'], gridRow+1, rowData[i].key);

But when I use these two lines in my code then everything works fine

// No error!!!!! grid.behavior.dataModel.setValue(colPos['bob'], gridRow, rowData[i].bob); grid.behavior.dataModel.setValue(colPos['pi'], gridRow, rowData[i].key);

Is the grid.setValue method the one to use or is the grid.behavior.dataModel.setValue method the one to use?

The error only seems to happen when the height of the div containing the Hypergrid is smaller than the height that the Hypergrid eventually grows to as rows are dynamically added.

研究方向
Examine the implementation of grid.setValue in the source code (likely in src/lib/Grid.js or similar). Understand how it calls dataModel.setValue and why it would fail when the container height is smaller than the grid's eventual height. The error suggests that the subgrid property is undefined, indicating that the cell or row is out of bounds. A fix might involve adjusting the row index handling, or ensuring that setValue delegates properly. Compare with the direct call to grid.behavior.dataModel.setValue which works, to identify the missing step.
