Hi,
Is there a way to obtain a list of pages in the app? Thanks.

That expression does exactly what you ask of it: checks if there is a
combination of five digits *somewhere* in the input string. You'll have
to anchor the expression to do what you really want.
So ^\d{5}$ should work.

Re: T5 regExp problem
Posted by Sige <si...@yahoo.co.nz>.
i might have found the reason:
it is not that @Validate("regexp") doesnt work, it
actually checked the input and think the input is
valid. However, it dosnt check the rest of the string.
for example:
zip-regexp=\\d{5}
@Validate("regexp") checks only the first 5 chars in
the input, and doesnt care about those following, and
all the following inputs would be valid:
12345
12345a
12345abcd
....
i have tested Tapestry 5.0.9 and 5.0.11 tutorial, and
i think this may be a bug.

Re: T5 regExp problem
Posted by Sige <si...@yahoo.co.nz>.
Thank you, but still no luck.
the only difference is that i use tomcat and i don't
pack the classes into a jar file. this doesn't seem to
be the problem, since regular expressions provided in
the tutorial work fine, such as:
zip-regexp=\\d{5}(-\\d{4})?
credit-regexp=\\d{4}(\\-?\\d{4}){3}

Since your regex is defined in a property file, you don't need to escape
your backslashes as you do with a java string.
try \-*\d*\.*\d*

Lance.

That's odd, it works for me alright... Tapestry doesn't do anything
special wrt. regular expressions, it just uses the java.util.regex stuff.

It seems @Validate("regexp") only support fixed number
of matches such as \\d{4}, and doesnt support "one or
more" or "zero or more" matches(\\d* or \\d+).

T5 regExp problem
Posted by Sige <si...@yahoo.co.nz>.
Hi,
I have tried to use a @Validate("regexp") to validate
a number field, the regexp used is:
numField-regexp=\\-*\\d*\\.*\\d*
However this doesnt work in T5 (5.0.9), the validation
is simply ignored, i have tested the regular
expression in Java correct. I wonder if T5 supports
all java.util.regex.Pattern, or what I have gone
wrong?
Thanks
Sige

Re: T5: obtaining a list of valid pages
Posted by Howard Lewis Ship <hl...@gmail.com>.
Chris is right, ComponentClassResolver is the service that "knows" the
pages, and could easily provide a list of pages.
I do have a concern that in the future, we may become a bit more
"dynamic" about what pages are available; i.e., pages with templates
but no Java class, or pages created from the aether (i.e., to support
some of the things Trails does in T4). I'm sure I'll be able to come
up with something reasonable.

The problem with this approach is that it doesn't address any other page
packages that may have been added via other modules (in the same manner
that additional component packages can be added).
The idea of copying what ComponentClassResolverImpl does would be the
'correct' method, and an extension to the API was request some time ago
to expose this as a legitimate feature. See:
https://issues.apache.org/jira/browse/TAPESTRY-1923. There's a patch
included that extends the interface as well as implements it. Hopefully
this will make it in...

Hi Angelo,
- get ContextClassLoader from current Thread
- get path of your pages package (org.exemplo.teste.pages) from ClassLoader
- get files on this path that ends with ".class", skiping inner classes.
I think this topic already has been discussed here.

I don't think there's any public API that you can use to get the list of
pages.
Still, i guess you can always copy what ComponentClassResolverImpl does.
That's the service that prints the list of all pages at startup.
