Conditional table converter (based on another field)

Hi guys,

i’m creating a new table for my project with this structure:

ID | ID_STATE | ID_USER | ..... So, my problem is this one: i’d like to convert the ID_STATE to a most presentable value, but to do that i need to access the corresponding ID_USER field (since i have a mapping in the db).
Can i do that with a converter? Basically i think i’ll have to extrapolate the rowId to get to the other properties…

Or should i write an extended version of table? And how?

Thanks a lot!

Not sure if this helps:

Table t = new Table(){
            @Override
            protected String formatPropertyValue(final Object rowId, final Object colId, final Property<?> property) {
                String result = super.formatPropertyValue(rowId, colId, property);
                if (colId.equals("ID_STATE")) {
                    result = //Maybe some enumerated state list
                } else {
                    return "";
                }
                return result;
            }
        };

Thanks a lot! That actually (almost) did it.
I was able to cast rowId into my pojo type and extract the data from there.

In other words:

Table t = new Table(){ @Override protected String formatPropertyValue(final Object rowId, final Object colId, final Property<?> property) { String result = super.formatPropertyValue(rowId, colId, property); switch(colId.toString()){ case "ID_STATE": result = connect_to_db(((myobj)rowId).getId()); break; ...... return result; } }; Thanks a lot!
