Let me post a summary of my experiences up till now: I had this disappearing texture issue while using Java3D v1.2. Upon upgrading to J3D v1.2.1 beta2 the problem was fixed. Other problems were introduced and since we are not using Java SDK/JRE 1.3 for our project, and this is a recommendation, we decided to downgrade to J3D v1.2 for the moment. However, if you do not face such restrictions, upgrade and the texture problem may be solved. Using Java3D v1.2 I fixed up a workaround, on switching the tab/page, by recreateing the objects which make up the texture, i.e. the Texture2D and the ImageComponent2D objects; fortunately the large BufferedImage object can be reused.
