Each time you want to show a new page in the Composer or if you start the Prototyper, Embedded Wizard needs to execute the Chora code for the initialization of the object and all embedded members. If the canvas area remains invisible, the reason is usually an error during the initialization of the object. Go to the log window and search for the first error message. If there are too many messages in the log window, clear the log messages and change again to the Composer page that shows the problem.
The following example shows an error during the execution of an Init() method:
To clear the log history, click with the right mouse button in the log window and select in the context menu item "Clear the log". Then scroll up to the first error message and solve the problem(s) from the top down to the bottom of the list. In case of multiple errors it might be helpful to clear the log again and repeat this procedure until you get your canvas area visible again.
