Vaadin Slider Not Showing on browser

I have a Slider component, but is not showing on the browser, only its caption is displayed.

Slider sampleSlider = new Slider("Test slider");
            setValue =  40;     
            sampleSlider.setMax(setValue);
            sampleSlider.setImmediate(true);
            sampleSlider.setMin(10);
            sampleSlider.setWidth("250px");
       controls.addComponent(sampleSlider);

Only the caption "Test slider" shows on a browser.

I am using Vaadin 7.4.8 now. It was same for V 7.4.0
It was working Ok for V 7.3.x

Regards.

SOLVED!!!

I found that the projectfile.scss had some componets removed from css

// Optimize the CSS output
$v-included-components: remove($v-included-components, accordion);
$v-included-components: remove($v-included-components, colorpicker);
$v-included-components: remove($v-included-components, grid);
$v-included-components: remove($v-included-components, popupview);
$v-included-components: remove($v-included-components, progressbar);
//$v-included-components: remove($v-included-components, slider);
$v-included-components: remove($v-included-components, splitpanel);
$v-included-components: remove($v-included-components, tree);
$v-included-components: remove($v-included-components, treetable);
//$v-included-components: remove($v-included-components, twincolselect);

After I commented line no 7,

All was good, in fact I had problems with twincolselect too, and commenting line for it, solved it.

Regards.
