upload files an zone
Hi all, I'm new to tapestry and have the following issue. I have a form with upload field in it. I use: @Property @Persist private UploadedFile file; After executing a button action, I try to refresh a zone, out of the form, and to fill it with the file content. Without zone it works fine, but I do not want to refresh the whole page, just the dynamic content part, so I put the zone, but after that I got some problem with the file persistence - it's not persisted at all, when I try to access it, I got null pointer.

For example, I want to have quot;add buttonquot; and by every click to add whole new tapestry page or component. I don't know how many addings will I have, I want this to be handeled dynamicly. It's like using spring to return ModelAndView object by ajax request and inserting it in some UI container. - Само сега спечели смартфон SAMSUNG и още много награди!виж http://www.specheli.eu/specheli-textgbg.php - Само сега спечели смартфон SAMSUNG и още много награди!виж http://www.specheli.eu/specheli-textgbg.php - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Re: upload files an zone
Standard tapestry upload component doesn't work with ajax requests and so it can not be used in zone. You can try custom solution like this: http://mutabra.blogspot.com/2012/07/tapestry-ajax-upload-fixin.html Or this: http://tawus.wordpress.com/2011/06/25/ajax-upload-for-tapestry/ On Tue, Aug 20, 2013 at 10:31 AM, nn kk inv...@abv.bg wrote: Hi all, I'm new to tapestry and have the following issue.

Re: upload files an zone
Unfortunately file upload in browsers is pretty archaic and ajax upload is quite difficult and requires a trick or two. For this reason tapestry-core only supports non-ajax file upload out of the box. If you use tapestry-jquery, you can use the ajaxupload component http://tapestry5-jquery.com/components/docsajaxupload Taha has also blogged about using valums file-uploader with tapestry http://tawus.wordpress.com/2011/06/25/ajax-upload-for-tapestry/ https://github.com/valums/file-uploader I'm sure if you google for ajax file upload you'll find various other libraries, some supporting drag and drop and multi file upload using various techniques (including flash) which wouldn't be hard to integrate with tapestry.
