You will need to provide more information that that one line before anyone is likely to understand the problem you are having.

the operation that I am creating renders a simple gradient from 0 to image width but in the middle of the image ends the gradient and starts again to the end of the image. I don't understand the reason.

You probably want to look at either the mandelbrot or the checkerboard operations and how they deal with coordinates. Be aware that the operaiton will be asked to render a subrectangle (with an x,y offset as well) and not it's entire output in one pass. This applies to all operations and is due to GEGL
supporting processing and generation of images larger than system RAM as well as that this design constraint will enable a future version of GEGL to be
performing paralell processing.

The API for writing operations is still settling, I hope you are looking at the latest version in SVN and not the last released version, since there has been considerable amounts of changes recently. (The next release of GEGL will be the first release where header files for writing custom operation plug-ins will be installed.)
