I have a three-level hierarchy in my data, and want to display this in a hierarchical grid. By following the examples in the demo section, I can create the grid to show Level 1 which expands to display results from Level 2 of the hierarchy. And, I can create a Grid that shows Levels 2 and 3. I can also display the three individual levels in grids of their own. What I cannot manage is having Levels 1, 2 and 3 on the same Grid. Firebug reports that there is an error in the template for Level 2 of the hierarchy - but, as mentioned, when this grid is rendered on its own, it functions correctly.
Maybe answers to the following question would help me;
- Do the grids for Levels 2 and 3 both have to be rendered using the 'renderInTemplate' method?
- Does it matter what order the grids are rendered in the html page?
- My filter for Level 3 checks a value from Level 2 - should it also include a value from Level 1?
