Trying to load data into a TreeStore. There is a Treepanel to which the store is attached.
The following error pops up:
Uncaught TypeError: Cannot read property 'parentNode' of undefined ext-all-dev.js:153509
The view of the treepanel is resized to be 18x its original width (??), and a folder icon without any text is shown.
The treestore has a model defined with 2 columns, "id" and "name".
A treepanel exists, (without any altering) where the store is bound to.
The treepanel is inside a panel, which itself is a tab of a tabpanel.
All elements were created with the Sencha Architect (lastest version).
Excerpt from the line where the error is thrown:
I debugged it, me.cellSelector is undefined, so oldCells is an empty array.
oldCells = oldRow.query(me.cellSelector);
row = oldCells.parentNode;
(I repeat: The complete UI was designed with the Architect and is pretty much "default").
What exactly am I doing wrong?
Do you need further code (especially mine?)
