Re: MYFaces and frames

1.) Tiles is working in MyFaces - no prob
2.) Tiles won't help you anything with client-side updates and resizing of frames

IMO, If you are using JSF, do not look at Tiles, particularly, if you are going to weave it into Frames.

It is not worth the effort ;-). I learnt it the hard way. The biggest problem in tiles and JSF I face is that the Tiles-Config.xml does not work in JSF environment. (Or maybe I'm missing something) which I think is the best thing about Tiles.

With some non-trivial _javascript_ it is possible to simulate the the resizing of panels using CSS panels or even HTML tables.

 

But the other nice thing about frames is that it supports a simplistic "partial update" mechanism.  That is, by using the 'target' attribute on an h:form + navigation rules, you can have a selection in one frame cause an update in a different frame.  This is pretty common behavior in non-web applications, and greatly improves the apparent responsiveness of the application.

 

I've heard that people have done things like using a zero-size-iframe and using _javascript_ to bit-blit into a CSS panel, but that sounds like a lot of work!

 

Is there another way in JSF or MyFaces to handle this?  Unlike most web developers, I have never looked at Tiles.  Does it provide some support for this?

 

Thanks,

Don

I know....Heard very often of the saying " Frames are Evil"  ;-) But there is one thing that we do not want to compromise on...

It is the resizing of the width of the navigation tree on the left. I know horizontal scroll bars will help but our user interface guide lines do not accept that. The user should have the facility to drag the width of the navigation tree on the left, just like how you do on the Eclipse Navigation View Pane.

 

I have not come across any solution for this other than frames yet. Probably a custom container component similar to JScrollPane in Java Swing might  help. But such a component on the HTML rendering?? *sigh* Need a lot of time for me to do that which is not at our disposal.

hi i know this is probably not the answer you like, but why do you want
to use a frameset? wouldn't it be better to use tiles, frames always
cause problems, especially dealing withbowser compatibility
