Howard M. Lewis Ship commented on TAP5-902:
-------------------------------------------
This may be possible by changing some of the semantics of the GDS interface;
i.e., prepare() called before getAvailableRows().
> GridDataSource does not allow performing less than 2 queries if returning
> results

> Key: TAP5-902
> URL: https://issues.apache.org/jira/browse/TAP5-902
> Project: Tapestry 5
> Issue Type: Improvement
> Components: tapestry-core
> Affects Versions: 5.1.0.5
> Reporter: Dan Adams
>
> By having getAvailableRows() and prepare() separate, any implementation is
> forced to perform 2 queries. Many systems allow getting the results of a
> query and the total count in one query so that you don't have to perform 2
> queries. Getting around this requires some pretty gross hacks (unless you
> just don't use grid at all which is unfortunate).
