Re: Tapestry 5.1 running in Google App Engine (GAE)
This apparently happens on 5.0.x as well, and seems to be a problem in the classloading on the local development server. Apparently this error doesn't occur (or at least isn't manifesting this way) on the actual appserver production engine.

User/error message that are not validation errors
Hi list, while trying to grasp the tapestry way of doing things, I stumbled on this question: I want to show a message in response to a submit. It is not a result of validation, but rather of the database state which is detected during data manipulation in the onSuccess event. For example, the submit is supposed to delete several entries in a database, some of which may have been removed by another process between the user selecting them and submitting the form. If this is the case, I want to show a friendly message to inform the user about this fact. Normally, after a submit, the same page should be re-displayed with updated data. I'm not sure how to incorporate the messages there. Can I use something similar to the t:errors/ component for this? That one uses a wording adapted to the input validation and uses error colors which don't fit here. Maybe I need to implement some similar behaviour by hand via properties into which the messages are put and display these by hand in the tml template? Another way would be to use an exception page. Can I use a special exception page that gets called automatically for some special type of exceptions? A normal page especially for user messages could be used, too, but what is preferred way? Is there a way that tapestry suggests for this situation, as it does for input validation?

Re: User/error message that are not validation errors
My Layout component has a message parameter of type Block that gets displayed if set. Pages that should display messages derive from a base class with a message page property of type string. In the page's template I then bind Layout's message parameter to the page's message property (coercion from String to Block is done automatically by Tapestry). In an event handler I then acquire a page instance by injecting it, set the message and return that page.

Pagination component for Tapestry4
Hello!
I'm working on one project with Tapestry 4 which makes heavy use of
paginated lists. They are at least 10 lists of different items in project.
This paginated lists have coulumns, optional filter and sorting upon some
columns.
I though of this in this way:
Application service returns a list of domain objects. Each domain object can
have tapestry component implemented. i.e. :
Class CustomerBean {
String firstName;
String lastName;
String phoneNumber;
//getters, setters, constructor
}
CustomerBeanComponent:
Template:
div jwcid=@Insert value=ognl:domainObject.firstName/
div jwcid=@Insert value=ognl:domainObject.lastName/
div jwcid=@Insert value=ognl:domainObject.phoneNumber
Specification:
parameter name=domainObject required=true /
Now PaginationComponent should take the ListCustomerBean and iterate over
this list with rendering of it's body component. This is similar behaviour
like For component but I would need pagination, filters and columns in
PaginationComponent.
Can you give me some guidelines how to implement this component and do you
think is it possible at all?
Thanks!

tapx-templating: using it in a t5 webapp possible
Hello, I'd like to use tapx-templating to generate some content. I want to integrate it into an existing t5 app (just for convenience). Unfortunatly when I try that, the hosting t5 application won't work anymore as expected, especially assets won't be found. Is it possible to use the actual t5 applications's classpath as the required classpath for t5? So that assets will be found both in the hosting webapp and in the generated offline content?

T5.1 If/Conditional against a method?
Hi all,
I've been searching the documentation/examples/list all morning, but
can't find an answer to this so far. Can T5.1 do a conditional
against a method instead of a variable (property)? I have something
like:
div t:type=If test=showFoo.../div
For the Java, I have tried numerous varieties of:
protected boolean showFoo() { ... }
(isShowFoo, getShowFoo, etc, etc)
I keep getting an exception that it can't convert showFoo to a
component parameter binding, then it shows me all the variables (not
methods) in my class. Of course, you can't put an @Property on a
method, either. Is it not possible in T5 to bind your conditional to
a method? (T4 could do this.)
Thanks,
mrg

Re: T5.1 If/Conditional against a method?
If you want the method to be showFoo(), then you need to do
test=showFoo().
But you can use test=showFoo if showFoo() is renamed to isShowFoo,
iff you change the accessor to public (from protected).
That is, for property access, tapestry is following java beans
conventions, and a property is only a java beans property if it's
public. :)

About Tapestry HttpServletRequest
I met a problem.
I upload files from a page. In the tranditional servlet, all things are right.
The code is :
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
DiskFileItemFactory factory = new DiskFileItemFactory();
// set cache
factory.setSizeThreshold(1024);
// set temp
String base = d:/upload;
File file = new File(base);
if(!file.exists())
file.mkdirs();
factory.setRepository(file);
ServletFileUpload upload = new ServletFileUpload(factory);
// set the single max
upload.setFileSizeMax(1000240l);
// set the whole max
upload.setSizeMax(1000240l);
upload.setHeaderEncoding(UTF-8);
try {
List? items = upload.parseRequest(request);
FileItem item = null;
String fileName = null;
for (int i = 0 ;i items.size(); i++){
item = (FileItem) items.get(i);
fileName = base + File.separator + item.getName();
// save file
if (!item.isFormField() item.getName().length() 0) {
item.write(new File(fileName));
}
}
} catch (FileUploadException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
but when I transfer these codes to a setupRender() of a tapestry page. After
debug, I found that after it go to List? items =
upload.parseRequest(request); , the varible items will be empty.
I use HttpServletRequest request = requestGlobal.getHTTPServletRequest(); to
get request object, it is not null.
any help?

Both of your suggestions worked (although I had to change the method
to public instead of protected for both). I didn't try Norman's
(although I'm sure OGNL would be fine) because I'm not using CK (at

Re: [T5] Security of files in the classpath
Hi Guys, Sorry to pull up an old thread, but there doesn't seem to be a lot about this topic. Was there ever a nice solution implemented for this? 2 years of tapestry framework development later and I can still download all my class files. I've restricted assets to authenticated users using a method like below, but I thought by now we wouldn't need to be adding custom solutions to manage this and it would be part of the core project?? Robert Zeigler wrote: I don't plan on changing the default configuration from whitelist to blacklist... it's the fallback. I'm a fan of deny unless explicitly authorized, as well. The AssetProtectionDispatcher takes an ordered configuration of AssetPathAuthorizer's, with the default whitelist implementation being the catch all final authorizer in what amounts to a chain of command. So you can certainly contribute your own implementations of authorizer on top of the default. Having a pattern matching whitelist would certainly be useful; I'm in a time crunch at the moment (and basically will be until the end of August), but in the beginning of September, I will rework the default WhitelistAuthorizer to accept url patterns.
