separateFolders in TreeGrid is ignored when using a DataSource

[Crack]

I have a TreeGrid with separateFolders enabled. After adding the "fields" property the folders are no longer sorted separately:

isc.DataSource.create({
  ID: "pathsDS",
  clientOnly: true,
  titleField: "path",
  fields: [
    { name: "id", type: "sequence", primaryKey: true },
    { name: "parent_path_id", type: "integer", foreignKey: "id" },
    { name: "path", title: "Name", type: "text" },
    { name: "isFolder", type: "boolean", hidden: true },
  ],
  cacheData: [
    { id: 10, path: "A/", isFolder: true },
    { id: 100, parent_path_id: 10, path: "Aa", isFolder: false },
    { id: 101, parent_path_id: 10, path: "Ab", isFolder: false },
    { id: 20, path: "B", isFolder: false },
    { id: 30, path: "C/", isFolder: true },
    { id: 300, parent_path_id: 30, path: "Ca", isFolder: false },
    { id: 301, parent_path_id: 30, path: "Cb", isFolder: false },
  ]
})

isc.TreeGrid.create({
  D: "pathsTreeGrid",
  dataSource: pathsDS,
  autoFetchData: true,
  width: 300,
  height: 300,
  separateFolders: true,
  sortField: "path",
  dataProperties: {
    titleProperty: "path"
  },
  fields: [{name: "path"}]
})

If I comment out the "fields:" line then sorting works (bug 1), but initial sort configured by "sortField" is ignored (bug 2).

Hi Isomorphic,

Could you take a look at this issue?

[Isomorphic]

We see the issue you reported with separateFolders:true and are looking into a solution. However, the issue with sortField that you reported as bug #2, isn't a separate issue - if you remove the separateFolders:true setting, sortField works.
