Textures unbinding when text isn't drawn (LWJGL/Slick-util)

I've been working on a game with LWJGL and came to a weird problem. Every time I decide to hide the text my textures seem to unbind. Here's all the code that is invlolved

Below is the code inside my Text class.

public void draw() {
        for (TextData textData : textList) {
            drawString(textData.getX(), textData.getY(), textData.getText());
        }
    }

void drawString(int x, int y, String text) {
        for (String line : text.split("\n"))
            ttf.drawString( x, y += ttf.getHeight(), line);
    }

Now the code in the main class

if (Keyboard.isKeyDown(Keyboard.KEY_H)) {
                hideText = !hideText;
        }

if (!hideText) {
            text.draw();
        }

This is the result

After careful consideration of my code I found out my Entity class was calling glBindTexture(GL_TEXTURE_2D, 0); while it was being drawn and drawing the text was enabling it again. Adding glBindTexture(GL_TEXTURE_2D, 1); at the end of my Entity drawing code fixed the problem. Thanks to the comments for helping me figure out the issue.

When text is drawn an image is bound to draw the text, i'm guessing that usually lwjgl/slick saves the current texture when drawing text and then rebinds it after. I would guess that it might be a bug where when hidden it doesn't rebind the texture but still binds another texture?
