Not sure that it matches what you want to do, but you could make your

tabgoup and read this env value in tabnavigation. Something like that :

RE: [T5] Grid totals
Daniel,
In our current solution we disregarded the paginator and always show the
total of all lines as showing page totals doesn't make sense in our
situation. But implementing this should not be a big problem as you can just
obtain the current page, the rows per page and thus generate your totals
from it.
Though my solution works, it feels like a hack and I will search for a more
elegant way after our initial launch ;-)
On my page/component implementing the Grid, I instantiate a new RowObject in
a @SetupRender method, loop though all (or just current page on paginator)
rows and sum the totals. Then in a @AfterRenderTemplate method I take the
DOM and add a TFOOT containing the totals to the TABEL element.
Below my (simplified) @AfterRenderTemplate method
There will most likely be very nice and elegant ways to inject into or
extend from the Grid component so everything can be done at the component
level and not the DOM. But I just needed something to work right now ;-)
Hope it helps,
Joost
---totals dom injection method--

void after(MarkupWriter writer){
//first find the table Element. T5 writes it in a div. Note that
//multiple tables in one component/page might cause issues

T5 Strategy for redirecting due to any error
Hi, this is more a question of technique than an actual problem. Some use cases: Lets say I have code that throws a NPE. I'd get a Tapestry error page that spills it's guts. It must use some technique for redirecting to another page at any point (might be too deep in the framework to harness that power) Lets say I have another page that requires a user session (ASO) -- the OnActivate method would do the checking and redirect to a page from there. Anyone can do this from OnActivate--so long as you know everything in the OnActivate() method, so it's not really interesting. Now lets say I have a page or component that checks a value that we could label as invalid, or we have a select component that can't be filled because a DB is down. Is there a way to redirect to another page at any point in the render process of a component or page? I think this would kind of fall along the lines of people who questioned how to replace the Tapestry error page with something more appropriate for the end user. Except that I'd want to be able to explicitly call/forward to an arbitrary page when my code comes across something abnormal. Does anyone have ideas or strategies about this?

[T5] ValueEncoder = TypeCoercer?
Hello again, I'm trying to write a CheckboxGroup / Checkbox pair of components for my project based on the RadioGroup / Radio components in the corelib. While doing so I stumbled upon the ValueEncoder / ValueEncoderSource and I keep wondering why are they introduced and why isn't the type coercion used instead (objectType - string, string - objectType)? Also in this direction, it would be good if one can contribute more dynamic type coercion configuration. E.g. if one uses Hibernate, one could contribute just one coercion handler that can turn any @Entity into a string and back (using the entity's declared @Id properties). This would greatly simplify Radio's, Checkboxes, Selects and the like.

Re: Tap5 - integrate several templates
all pages and components are technically consider the same thing within t5. all components/pages wrap there content (what is between the tags t:component/pagecontentt:component/page) within the wrapping component template you specify a t:body/ component. This directs the template as to where to insert the body content. ex: border component html head.../head body t:header/ t:body/ t:footer/ /body /html any page which you wanna use the border on t:border content /t:border note how the border component calls a header and footer component to insert at the top and bottom of the body. ~evan - Original Message - From: Anujith Amaratunga [EMAIL PROTECTED] To: users@tapestry.apache.org Sent: Wednesday, August 01, 2007 12:18 PM Subject: Tap5 - integrate several templates Hi, How do I integrate several templates into one page? i.e I have a header and a footer which needs to go into all the pages, but I don't want to duplicate code in all pages.

[T5] Any component Bis
Hi,
The Any component is gone and now
div t:type=any class=prop:someProperty.../div
is now just:
div class=${someProperty}.../div
but is it possible since it's gone to add a mixin to and element like
div t:mixins=myLayoutMy layout/div
When I try this case tapestry throw me this error :
You may not specify mixins for element div because it does not
represent a component (which requires either an id attribute or a type
attribute)
Ok so a :
div t:id=myId t:mixins=myLayoutMy layout/div
Embedded component 'subLayout' has no type. You should specify a type
in the component template, or define the component inside class
Any solution ?
Thanks.
Re: [T5] Any component Bis
after some more research it seems that mixins have to be applied to a
specific component type of specific instance of a component type. i dont
think you can mixin for generics. i think a component minus a template is
more what your looking for.

T4.0.2: Is compatible Tacos(Dojo) with any Browser??
Hi, I need a guide about of compatibility of Tacos (or Dojo) with browsers. I made a page that works in IE6 and IE7, but it does not in Firefox. In particular, the page is a component tacos:Tree whose links throws a tacos:Dialog where things are edited and saved, finally go back to refreshed tree. In IE the tacos:Dialog works and is a good render, but in FireFox it does not work and watching the resulting code of the generated render its bad. In Firefox the attributes delayedLoad and loadElement of the tree work well, but in IE no. Tacos (or Dojo) has a configuration for each browser? Perhaps this problem is resolved in version 4.1 of Tapestry, but i am not safe of change to this version because version 4.1 is not stable. For Any idea or aid many thanks.

A couple questions: Your generic page -- I just got back into extending pages (the T4 way). I am putting my abstract orbase pages in the /base directory. This seems like the proper place to put them, right? 2nd: With an ApplicationScoped bean, is that per session or one for the whole application? It seems like having one for the whole app would cause issues with one person receiving another person's error flag. I guess I am confused a little--when say ASO, I think of it as existing for a current user's session only. (Another person using the app would have no direct knowledge of the ASO) On 8/1/07, Joost Schouten [EMAIL PROTECTED] wrote: Daniel, I just setup a system where I have an ApplicationScoped bean hold a String authenticationDeniedMessage (could obviously be any error message). On my GenericPage which all my pages extend, I check on the @CleanupRender if this String != null and if so, redirect to my AuthetnicationDenied page. This page renders the message in clears it on @CleanupRender so any subsequent request will work again. This setup allows me to deny access to a page at any point of my page lifecycle without Declerative or Runtime Exceptions.

Some use cases: Lets say I have code that throws a NPE. I'd get a Tapestry error page that spills it's guts. It must use some technique for redirecting to another page at any point (might be too deep in the framework to harness that power) Lets say I have another page that requires a user session (ASO) -- the OnActivate method would do the checking and redirect to a page from there. Anyone can do this from OnActivate--so long as you know everything in the OnActivate() method, so it's not really interesting. Now lets say I have a page or component that checks a value that we could label as invalid, or we have a select component that can't be filled because a DB is down. Is there a way to redirect to another page at any point in the render process of a component or page? I think this would kind of fall along the lines of people who questioned how to replace the Tapestry error page with something more appropriate for the end user. Except that I'd want to be able to explicitly call/forward to an arbitrary page when my code comes across something abnormal. Does anyone have ideas or strategies about this?
