Re: T5: Removing empty valued columns from grid (A Solution)

[Fermin Da Costa Gomez <da...@dcgconsultancy.nl>]

For those that have a similar requirement to the one i have/ had i herewith
post my (current) solution

I load the model via a separate method after i retrieved the result set from
the search.


...

private void loadModel() {

// Get the columns from the resultset that actually contain data

_searchResultFilledFieldNames =
ResultManager.getFieldColumnsContainingValues(_resultSet);


 _myModel=_beanModelSource.createDisplayModel(ISearchResult.class,
_componentResources.getMessages());


                // My implementation of a BeanModelSource

LuceneResultBeanModelSource lbm=new LuceneResultBeanModelSource(
_beanModelSource);


                // Actually generate the model based on the supplied
columns/ fields

                // In the method only those columns are added that have to
be shown

_myModel=lbm.generateBeanModel(_searchResultFilledFieldNames,
_componentResources);


 }
...


This does the trick i was looking for: Do not show any columns that do not
contain any data!


Cheers,
