Lookup fields not working on jtable
-----------------------------------
Key: CAY-912
URL: https://issues.apache.org/cayenne/browse/CAY-912
Project: Cayenne
Issue Type: Bug
Components: DataViews
Affects Versions: 2.0 [STABLE]
Environment: JRE 1.5 + Windows Vista :-(
Reporter: borgo
Assignee: Andrus Adamchik
I have tried to use DataViews with the following example code
(http://cayenne.apache.org/doc20/dataviews-in-action.html)
The DataViews documentation It's not clear about use the lookup when editing a
JTable.
Two problem arise:
1) Lookups combobox are always empty
I have look at createTableCellEditor() methods in CellEditors
Here the method field.getLookupValues() returns always an empty list.
The cause is getRootOwner().getLookupCache().getCachedValues(lookupField) that
returns always an empty list.
I think it's because I haven't setting any data in the cache.
But how could I do that ? Does I need to create query in the modeller ?
Unluckly, documentation and examples doesn't help to understand how cache and
lookup fields works.
2) So I have tried to use a custom method to load the lookup combobox.
Here is another problem: when I pickup an element, the cell in the table is not
updated and becomes empty.
there is no way to update the cell choosing elements from the combo.
I'm very interested in DataViews. My first reason to use Cayenne is the
presence of DataViews.
I'd like to give my contributes to that project but first we need a working
base to develop on.
