Vertical Split Panel is not working

I have a split panel but I cant drag the split line…
I dont know why…
I am using the Dashboard demo template…

VerticalSplitPanel split = new VerticalSplitPanel();
        split.addStyleName(ValoTheme.SPLITPANEL_LARGE);
        split.setLocked(false);
        split.setFirstComponent(buildFirstComponent());
        split.setSecondComponent(buildSecondCompoent());
        addComponent(split);

this is the result view

I solve this by Compiling the theme :slight_smile:
My Mistake sorry :slight_smile:
