Re: Customising D2W - adding filtering to list pages
Three things, I can think of three things you might find helpful... 1) as Mark has already pointed out, you can use the useBatchingDisplayGroup key. That will cause the list page to use a ERXBatchingDisplayGroup instead of a regular WODisplayGroup. The difference there is that the ERXBatchingDisplayGroup fetches raw rows and only converts them to EOs when needed. 2) Travis Cripps has recently added a ERDQueryValidationDelegate to the ERD2W query page. It is bound to the queryValidationDelegate d2w key. You can use this to validate input on a query and throw 'validation' errors related to the query. It looks pretty handy (^_^) 3) check here: http://wiki.objectstyle.org/confluence/display/WO/D2W+Flow+Control Specifically the part regarding the ERDQueryDataSourceDelegateInterface. You can step in and hijack the process there. You'll have complete control over the fetchspec, the qualifier, the datasource... the whole shebang.

Re: Customising D2W - adding filtering to list pages
Hi Ramsey, It looks like ERDFilterDisplayGroupButton includes a check for allowsFiltering itself so that I don't think ERNEUListPage needs modifying in this case.

Re: Customising D2W - adding filtering to list pages
Dear Ramsey, Thank you very much. I'll explore the use of ERDFilterDisplayGroupButton which I had ignored previously! I also didn't realise the existence of the showListInSamePage key so I'll look through the Wonder search to find out more!

Re: Customising D2W - adding filtering to list pages
Hi Daniel, I might be able to answer that! I see in the source for ERD2WListPage that it creates a displaygroup first checking the key "useBatchingDisplayGroup". I suspect that if you set that key then the list page will properly batch your entities rather than simply paginate. I hope that is what will happen as I will have need to use that soon Best wishes, Mark 2009/11/2 Daniel Beatty : > Greetings Ramsey, > Got a follow up question for you.

Re: Customising D2W - adding filtering to list pages
Greetings Ramsey, Got a follow up question for you. Is there a way to have D2W use a throttle back mechanism for queries that would otherwise overwhelm the server? For example, I am building a D2W app for a database schema that was badly designed, and some queries, especially wild card, will overrun the memory quickly.Thus in those cases, something like the old Display Groups mechanism for limiting results to the first 100 or so would be nice.
