Compule and Run without "properties.setProperty("idRegion", topicCategories);"
code and check check "checkboxprop.properties" file to see the saved data?
If not, check data of topicCategories. Is there any retrieved data on
topicCategories?
Any how, use this
http://download.oracle.com/javase/tutorial/essential/environment/properties.html
for your reference site.
