OpenLazlo and Tapestry
Have you heard of OpenLaszlo yet?
http://www.openlaszlo.org/demos#Laszlo%20Components%20in%20OL4
is this "compatible" with Tapestry (maybe Tapestry 5?) or a theoretical
possible to also integrate such technologies into Tapestry?
Maybe pages and components could be rendered into their Flash counterparts
without the Tapestry programmer having to worry about the details?

Re: Component timeouts and an NPE
Posted by Bryan Lewis <br...@maine.rr.com>.
The easy solution is, don't use private variables like that. Declare
them as persistent page properties. Do your development with caching
disabled so that the problem appears right away, rather than after a
ten-minute garbage-collection period.

Any idea where I can set the timeout? Or if I can find a way to disable it. What I have to do is put a null check around access to the variable and then re-create the list if it is null.

Component timeouts and an NPE
Posted by Mark Stang <ms...@pingidentity.com>.
Hi,
I am seeing Tapestry 3 components with values which is good, say a ArrayList:
private ArrayList<ConnectionItem> displayList;
If I don't touch the component for 10 minutes or maybe a little longer, then the "displayList" is null. I assume that this is due to Tapestry putting it back in the pool. However, I then get a NPE. Any idea where I can set the timeout? Or if I can find a way to disable it. What I have to do is put a null check around access to the variable and then re-create the list if it is null.
thanks,
Mark

Posted by Mark Stang <ms...@pingidentity.com>.
Hi,
I have some .js scripts that I am specifying external to the Shell component. Is there a way to add them to the Shell component?
thanks,

I have attended Flex presentation by Christophe
Coenraets
(http://coenraets.org/blog/2007/01/flex-data-management-services-tutorial/)
and was quite impressed (even I hate Flash ads).
I am convinced that rich flash applications are the
next big thing (web 3.0).
I wish it was JVM and Java Web Start, but because of
non modularity of JRE and inconvenience of installing
I believe that FVM (Flash VM) will be the king on
clients...

When I'm think about Flex, movies is the last thing on my mind lately. I'm
intrigued by the potential of Flex apps and/or Flex hybrid apps. I don't
think Tapestry will be particularly well equipped to create complete Flex
apps (but do correct me if I'm wrong). It would be really nice though if
we could easily create hybrid applications using Flex components tied to
our 'regular' HTML/CSS/JavaScript components using Flex's Ajax Bridge
technology.

Anything is possible, of course. The idea of creating Flash (i.e.,
Flex or Laszlo) movies on the fly is intriguing. At one extreme, you
could get Tapestry to directly create and spool out the bytestream of
the movie, on another you could use Tapestry to generate the XML
descriptor from which the bytestream is generated. There's lots of
options.
It's just a matter of developer bandwidth ... something sorely missing
from my life right now. Viva T5!
