This example code from "test case examples.lisp"

<application-window title="OpenGL 3D" margin="12" width="300"  
height="300">
   <column align="stretch" valign="stretch">
     <row minimize="vertical" align="stretch" valign="middle">
        <label text="red" align="right" width="50"/>
        <slider name="red" action="adjust-vertex-color-action" max- 
value="1.0" flex="1"/>
        <label text="0.00" name="red label" width="40"/>
     </row>
     <row minimize="vertical" align="stretch" valign="middle">
        <label text="green" align="right" width="50"/>
        <slider name="green" action="adjust-vertex-color-action" max- 
value="1.0" flex="1"/>
        <label text="0.00" name="green label" width="40"/>
     </row>
     <row minimize="vertical" align="stretch" valign="middle">
        <label text="blue" align="right" width="50"/>
        <slider name="blue" action="adjust-vertex-color-action" max- 
value="1.0" flex="1"/>
        <label text="0.00" name="blue label" width="40"/>
     </row>
     <spacer height="12"/>
     <triangle-opengl-dialog name="opengl" vflex="1"/>
     <spacer height="12"/>
     <row align="stretch" valign="stretch" vflex="2">
       <triangle-opengl-dialog name="opengl2" flex="1"/>
       <spacer height="12" width="12"/>
       <triangle-opengl-dialog name="opengl3" flex="1"/>
     </row>
   </column>
</application-window>

results in this error:
