#17 bad generated code when setting layout of frame to BoxLayout

[Johan Guiheneuf]

Operating mode:
1. Creates a new v4all file
2. Add a JFrame in the GUI editor
3. In the properties pane, in the category Container,
in the field Layout, select BoxLayout from the combobox
4. Add a JPanel in the JFrame
5. Click on the button "Generate code for Swing and run"

Expected result:
the frame is displayed in the center of the screen

Obtained result:
There is an error: "java.awt.AWTError: BoxLayout can't
be shared..." and the code is not executed.

Explanation:
In the class Gui_1, in the method
getFrame100ContentPane, there is the following line:
ivjFrame100ContentPane.setLayout(new
javax.swing.BoxLayout(this, javax.swing.BoxLayout.X_AXIS));

This line is incorrect. v4all should generate the
following line:
ivjFrame100ContentPane.setLayout(new
javax.swing.BoxLayout(ivjFrame100ContentPane,
javax.swing.BoxLayout.X_AXIS));

As it is an automatically generated part of the code,
it can not be changed by the developper of the GUI
without being overwritten by v4all at the next code
generation.
