setSelectionMode for CheckBoxSelectionModel doesn't work

[cupakob]

Hi *,

in my grid i need a checkboxes for each row, so I'm using CheckBoxSelectionModel and setSelectionMode. Here my code:

List<ColumnConfig> configs = new ArrayList<ColumnConfig>();
// Needed to insert a checkbox at begin of each search result
final CheckBoxSelectionModel<ModelData> sm = new CheckBoxSelectionModel<ModelData>();
sm.setSelectionMode(SelectionMode.MULTI);
configs.add(sm.getColumn());
configs.add(new ColumnConfig("kurzbezeichnung", "Kurzbezeichnung", 300));

The result is:

And now i have 2 problems:

1. Select all checkbox is not working
2. I can check only one checkbox from the table, two or more isn't possible.

Can someone tell me, what i'm doing wrong?

Thanks in advance!

So, you looked at the examples right?

There is one line, that you are probably missing. But this is only guessing because you have not posted a fully working testcsae:

grid.addPlugin(sm);

maybe not, i'm missing addPlugin(sm)....I'll try it

edit: with addPlugin(sm) i can check more than one row. Another question: the checkbox for "Kurzbezeichnung" in my example - has this checkbox only display function (to see, that all rows are selected)?
