In Wicket-Examples, Repeaters, there's an example of a DataTable from Wicket-Extensions. The data provider supplies lists of javabeans, each bean representing a row in the table. The PropertyColumn object for each column of the table gives information about the column title, its sortability, and the non-OGNL string used for pulling a cell's data out of the bean.
In this example, the column names are hardcoded as bean properties, but what I want is to display any arbitrary JDBC ResultSet in a DataTable. Has anyone written code to do that? (And if so, could I see it? ASP.NET has this feature, and I'm rewriting code that uses it.) If not, I was thinking that I could implement IDataProvider to contain information about the number and names of the columns taken from the ResultSetMetaData. The data provider would hold a list of row objects, each of which would be (or contain) an indexed sequence (an Array or ArrayList) of atomic data objects, obtained by calling "resultSet.getObject(index)" varying "index" within the column count. My subclass of DataTable would be constructed with this data provider as an argument. A loop (indexed within the column count) would create a list of PropertyColumn objects -- each with the display model based on the column name recorded from the ResultSetMetaData, and a non-OGNL property expression that makes use of List/Array indexing to access the specific field in the row. Does this sound like a good approach, or am I re-inventing the wheel here? ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
