Hello,

I am trying to build a grid using GXT 3.0.0 as the BasicGrid example provided by Sencha. However, I have spent a while to figure out why my header doesn't get a modern and clean CSS style. Do you have any clues in order to solve this problem?

I do inherit the com.sencha.gxt.ui.GXT and add the reset.css file in my project.

Code:
    protected void buildGrid() {
        final ColumnModel<AlertDto> cm = new ColumnModel<AlertDto>(buildColumnConfig());        
        store = new ListStore<AlertDto>(props.id());        
        grid = new Grid<AlertDto>(store, cm, new GridView<AlertDto>());
        grid.setBorders(true);
        grid.getView().setAutoFill(true);
        grid.getView().setStripeRows(true);
        grid.setAllowTextSelection(false);
        this.setHeaderVisible(false);
        this.add(this.grid); // added to a ContentPanel
    }
Thank you for your help,
Thomas
