About org.apache.tapestry.contrib.jdbc

[Ueyama <ue...@mobster.jp>]

Hello!

I found a package [org.apache.tapestry.contrib.jdbc] in TApestry API 
Documentation. but the detailed usage is not indicated. 
Do you know about detailed usage of org.apache.tapestry.contrib.jdbc
 package, or URL of the sample of it?

I want to make Tapestry Application with jdbc driver and support tool 
for it. (Without O/R mapping Tool for example Torque,Hiberate etc.)

Thanks
Yoshinari Ueyama

Form submit Error

[il...@dev.kck.ru]

Hi, Tapestry users!

Mabe you know the solution for such a problem.
I have a component(Combobox) after user chooses an item from this combobox 
form wich wraps this combobox is submitted
(I need it  to make changes in Database and to display proper output 
according to this changes).
On my page I have several comboboxes of this type. so when I make a choice 
in one of them and then very quickly make a choice in another one
I receive the following error:

org.apache.tapestry.ApplicationRuntimeException
Action invoke error. Origine message:Page recorder for page 
matrix_solutions is locked after a commit(), but received a change to 
property matrixSolution of component matrix_solutions.

As I understand this is becouse the page after submitting a form is not 
rendered, but the listener receives a message to change some property and 
this couses the error.
Have you any ideas how to solve it?
Maybe Tapestry has a buildin solution?

Thanks in advance.
