Users - Jpublish to Screens
Locked

Yes and no.
I think the main difference that you need to remember is that jpublish is simply there to make html documents, while the widgets (screen, form, tree, menu) are put together so that other technologies can take advantage of them. In transitioning an application that made use of jpublish so that it "just has to work", you should take on the approach that the other applications have done using the simplest "transitional" tool (in this case screen.render and the continued use of ftl) as the majority of the community has been web browser centric. However, as far as maintanence and extensibility and reuse and all of the things that Ofbiz has the potential to take advantage of (inside and especially outside of the html world), you're better off utilizing a widget approach. Freemarker is great for creating html, it's easy to use, etc. But, if you can store your presentation information in a generic format it will be much more useful. But, again if it just has to work in an html environment, why are you updating away from jpublish? ========== Tibor wrote: Hi Chris Please tell me if I understood this properly: you say that I should do my page declaration as a combination of widgets, widget-includes, decorators, instead of inserting bits of pages (ftl) into a base ftl ?

Thanks Chris
very interesting response, I completly understand the multiple channel output approach for ofbiz. but indeed I am only intersted by the html output, but I thought screens and widgets were the way to go and I just went on using what was proposed in Sequoia. do you think I should stick to JPublish ? now I'm done and have both versions running, but please tell me which one would be the best choice to make? Thanks for sharing experience Tibor

Hi Tibor,
A couple of months ago I posted a request for help with a problem very similar to yours. I totally agree with you on your comments in this matter. I solved my problem by editing the source code responsible for this misbehavior. Unfortunately, I can't share my solution with you, since the class containing this problem has undergone other, more extensive customizations. If used, it would most likely brake some of your code elsewhere. But if you're intrested in a solution and don't mind toying with the source code, here's the source of the problem: FreeMarkerWorker.renderTemplateAtLocation() Basicly you need to help FreeMarker find your ftls by supplying the right template loader. You may find these resources helpful: http://freemarker.sourceforge.net/docs/pgui_config_templateloading.html http://freemarker.sourceforge.net/docs/pgui_misc_multithreading.html Good luck! </Firas> ________________________________________________________Original Message Message: 6 Date: Mon, 13 Mar 2006 17:07:37 +0100 From: "tibor katelbach" <[hidden email]> Subject: Re: [OFBiz] Users - Jpublish to Screens To: "OFBiz Users / Usage Discussion" <[hidden email]> Message-ID: <[hidden email]> Content-Type: text/plain; charset="iso-8859-1" Hi Chris Please tell me if I understood this properly: you say that I should do my page declaration as a combination of widgets, widget-includes, decorators, instead of inserting bits of pages (ftl) into a base ftl ?
