Re: Component that displays additional containing Page markup
Grid is much more powerful than I knew. Thank you guys for nudge in the right direction. I will be sticking with my component for this particular page, but I am replacing allot of other code with Grid. t:body/ did the trick and works like a charm. Cannot believe I didn't see it earlier. Thanks again, Bogdan. -- View this message in context: http://tapestry.1045711.n5.nabble.com/Component-that-displays-additional-containing-Page-markup-tp5718622p5718742.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

Re: Component that displays additional containing Page markup
I've written a simple gallery component which displays a list of items in a grid with prev and next links to go through pages. You pass it a block to display each item.

Re: Component that displays additional containing Page markup
Pagination is the reason for not using the Grid component. I want to paginate my results without holding anything in memory (session). For Grid I will select the entire set, @Persist it and then display portions on the page. What I am doing is a bit different. I always select the (number of tokens I need to display) +1 by using SQL Limit A,B. If I have NumberOfTokensToDisplay +1 in the list it means there is another page, if not, well not :). The only thing I need to compute is nextPage number, which I put as context to Next eventLink. Much cleaner in terms or resources then holding an entire list of results in memory, and no cleanup required when I'm done. Thank you Lance, I'll have a look at your demo.

Just implement a GridDataSource and pass it to the Grid's source parameter.

Re: Component that displays additional containing Page markup
As Thiago has said, the Grid component actually accepts a parameter of type GridDataSource so does not require the entire list in memory at once. Tapestry provides a coercion from List to GridDataSource so you can also pass a List to the Grid. http://tapestry.apache.org/typecoercer-service.html#TypeCoercerService-ListofCoercions -- View this message in context: http://tapestry.1045711.n5.nabble.com/Component-that-displays-additional-containing-Page-markup-tp5718622p5718684.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

Re: Component that displays additional containing Page markup
The other limiting thing I remember about the Grid component was that I could only display one Object' per row. I could not do: Object1.Name Object2.NameObject3.NameObject4.Name Object5.Name Object6.NameObject7.NameObject8.Name As you can tell, I did not look at the Grid component for a long time now. I'm at work and cannot test it out. Can't wait to get home :))). Believe it or not, I am working on a legacy Struts application for a client. Painful stuff.

As Howard said, the BeanModel-based components (Grid, BeanEditor, etc) are not supposed to do everything, but to do something specifically and well.

Re: Component that displays additional containing Page markup
We use GridDataSource for paging large sets too. getAvailableRows is the total number of entries prepare tells you the slice to be rendered depending on grids rows per page setting. Simply load the whole slice in prepare and return the single row entity by getRowValue Jens Sent from my iPhone On 13.12.2012, at 19:12, bogdan_cm bogdan.iva...@rbccm.com wrote: I will have a closer look at the Grid component.

Re: Component that displays additional containing Page markup
Hi!
From an Object oriented aspect you are coupling components to particular pages,
when I understand you correctly. This is for my personal opinion a wrong
design. Can't you not just pass the additional info as parameter from your page
to your component (as Taha suggested it)?
Or are you displaying commen/shared info? Maybe tapestry's layout might be a
solution for you?

I would like to write:

maybe a loop here that would read a list in the Page containing the

Re: Component that displays additional containing Page markup
Thank you both for replying. Now that I read it after a day, my question is not very clear. Here is a more to the point explanation. My custom component will take care of pagination. This means I need my component to wrap around a Loop in the main page. The Loop will be iterating over a List of results. The code I am hoping for is: html xmlns:t=http://tapestry.apache.org/schema/tapestry_5_3.xsd; -- tapestry Page t:myPaginationComponent params= (will tie pagination variables from page to component params) loop ... html that displays list entries /loop /t:myPaginationComponent /html I will explore the block suggestion.
