[OPEN-1407]GridPanel w/ CheckboxSelectionModel can hide all columns (except checkbox)

[Andreas B.]

Ext version tested:

• Ext 3.2 rev 1

Adapter used:

• ext

css used:

• only default ext-all.css

Browser versions tested against:

• FF3 (firebug 1.3.0.10 installed)

Operating System:

• Windows Vista Business

Description:

• When using a GridPanel with CheckboxSelectionModel (so checkboxes a are shown in the first column of the grid) it is possible to hide all columns except the checkbox column. Now it gets worse because the checkbox column has no column header and so it is not possible to show a column again, except a page reload. If you use StateManagement then you are really lost because then there is no way, except clearing the state, to show the columns again.
  I think its a bug because a GridPanel without CheckboxSelectionModel does not allow to hide the last visible column

Test Case:

    Just use a simple GridPanel with a CheckboxSelectionModel

Steps to reproduce the problem:

• Remove all columns of the GridPanel by using the header menu
• After removing the last one, there is only the checkbox column left.

The result that was expected:

• The GridPanel should check if there is at least one column with a header menu left. Otherwise hiding should not be possible.

The result that occurs instead:

• All columns, except the checkbox column, can be hidden. Now there is no way to show the columns again.

Screenshot or Video:

• no

Debugging already done:

• no

Possible fix:

• not provided

Can't you just configure the CheckboxSelectionModel with menuDisabled:false?

[Andreas B.]

Okay thats a working solution for us. I also have to set groupable: false to the CheckboxSelectionModel, otherwise the "grouping" checkbox in the menu could be clicked.

But it's still a bug I think. Or if not it should be documented that these config properties can be set on CheckboxSelectionModel. There are no config properties "menuDisabled" and "groupable" in the API docs of CheckboxSelectionModel.

Why is this bug closed now?

[Jamie Avins]

We're going to update the documentation.

[Andreas B.]

The documentation has not been updated until now! Even not with ExtJs 3.3.0!

[Andreas B.]

It's still undocumented. Please reopen the bug report.
