ShapeRenderer colors stop working when rendering images with SpriteBatch

Question

I've made a game that uses ShapeRenderer for making colorized lines. This worked fine, but when I start to import images the colored lines suddenly became black. Worst of all: When I'm using a background the lines doesn't show at all, and yes, i'm drawing it in the right order....

Code for importing and rendering the images:

Constructor(){
    TextureAtlas atlas = new TextureAtlas(Gdx.files.internal("data/texture.atlas"));
    AtlasRegion region = atlas.findRegion("path");
    Sprite sprite = new Sprite(region);
}

..........................................

@Override
public void render() {
    Gdx.gl.glClearColor(255, 255, 255, 1);
    Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);

    batch.begin();
    background.draw(batch); // drawing the background

    drawing.draw(); // drawing the lines
    drawObjects(); // drawing some pictures
    batch.end();
}

But when I remove the code for rnedering the background and the pictures the lines will show up and in the right color....

Please help!!

EDIT: Drawing with the ShapeRenderer looks something like this (Don't have to put everything in):

public void draw() {
    shaperenderer.begin(ShapeType.Line);
    shaperenderer.setColor(Color.RED);
    shaperenderer.line(1, 1, 100, 100);
    shaperenderer.end();
}

You cannot nest objects that depend on OpenGL context. Specifically, you are nesting a ShapeRenderer.begin() within a SpriteBatch.begin(). If you change render to look like this:

batch.begin();
background.draw(batch); // drawing the background
batch.end(); // end spritebatch context to let ShapeRenderer in

drawing.draw(); // drawing the lines (with ShapeRenderer)

batch.begin(); 
drawObjects(); // drawing some pictures
batch.end();
