Lazy loading of oneToMany associations

[andy.2003]

Hello,

I currently evaluating the smartgwt enterprise editon. As seen in the following examples:
http://www.smartclient.com/smartgwte...ationOneToMany or http://www.smartclient.com/smartgwte...r_detail_batch
all one-to-many relations are fetched eager. I have quite complex related entities so using this aproach is to slow. Is there a way I can enable lazy fetching of one-to-many relations within smartgwt, so when I select a record its relations are fetched on demand.

Thank You
Andreas

SmartGWT does not force one-to-many relations to be eagerly fetched. See this overview of what actually happens and how you can control it.

Thank you for your reply!
Am I right, that there is no support for lazy loading of related Data for OneToMany relations in databound components? Especially I would like to have the same UI experience like in the examples of the 1st post, but without eager loading.

You can fetch data from other, related DataSources at any time.. we'd recommend a second, slow pass through the QuickStart's Data Integration and Server Framework chapters (even if you think you've seen it all), then you could look at ListGrid.fetchRelatedData(), but this is really just a helper method. See also DataSourceField.foreignKey.
