    Default Treepanel expand/select issue

    Ext version tested:
    • Ext 5.1.0 rev 107
    Browser versions tested against:
    • Chrome
    DOCTYPE tested against:
    • N/A
    • This might be related to EXTJS-13133 which was fixed in 5.0.2. When using checkboxmodel as selection type in a treepanel, the rows get selected when expanding the nodes.
    Steps to reproduce the problem:
    The result that was expected:
    • Rows should not be selected when expanding nodes
    The result that occurs instead:
    • Rows get selected

    It's not really intended to use the checkbox model for trees, since trees have their own selection model subclass. Regardless, you could use checkOnly: true if you only want selection via the checkbox. Otherwise, I don't really see a bug here.

    I am using Extjs 5.1.0

    I am using checkbox selection model within tree panel.

    when we expand the tree more than once i.e open, close and then open, the selection of the child nodes goes away.

    I am not sure if it is possible to persist the selected child nodes on expand when using checkbox model.

    I am not using the checkbox. Normal / expected behavior for trees is to have the ability to expand a node without selection. This option should be configurable with the default being no selection. The fact that the selection event fires before any expand events makes implementing normal tree behavior problematic.

    Combine this with routing and you get a bad user experience.
