Updating and reading values from Smartdashboard.

Hi all,

I am using smartdashboard for image analysis - there is no connection with a robot whatsoever.
The method processImage contains what I need for the calculation:
Code:
@Override
    public WPIImage processImage(WPIColorImage rawImage) {
1- If I have this line of code:
Code:
Robot.getTable().putString("MSG", "message 1");
I can see the message displayed on the dashboard. But if further on in the code I have the same line with "message 2", I do not see it displayed, MSG still says "message 1".

2- I have also tried to to read values that I have set with Preferences/Keys/Values by using:
Code:
int threshold = Robot.getPreferences().getInt("Threshold");
But the SmartDashboard does not display anything (it might be stuck at the line above) when I have this line of code.

3- I thought that SmartDashboard keeps calling the method processImage. Should not I see the displayed values updated depending on the image (like number of polygons found, distance to target...etc.) ? Only the image and whatever I draw on the image changes.

Anybody knows what am I doing wrong (on top of volunteering )? Thanks.
