I did a small extention to lookup autocompleter code and now it is able to load description for the lookup field values.
For example when you load a form with lookup fields, currently you see only the Id in the lookup field (which is not very descriptive). After applying the patch, you will see also a description, next to lookup button. The description value is the same one that appears in the autocompler and it is specifiued for in each lookup screen.
You will see the description also when a value is returned from a lookup screen or when a value is selected from autocompleter or when you type a valid Id in the lookup field.
Internally it does an ajax call to get the description for the supplied value in lookup field.
I'd like to know if you want to see this feature in ofbiz and/or if you have any ideas to improve it.
