Basic Problems

I created a HTML Block, but everytime I restart the server, the FileId is lost

Blocks are persisted into the database. Sometimes a value you entered through the application may not find it's way into the table 'nuke_services_attributes'. It is a good idea to have a look into that table. In case of the problem described above you can find a row with the 'pn_sid'='org.jboss.nukes.core.modules.html.blocks.HtmlBlock/' and the 'pn_aid'='FileId'. If there is some other value or NULL in the field pn_value, just update this row to reflect the FileId you need.
