automatic form validation not available in IE
hi,
I am developing web applications for five years now, using PHP, ASP,
Zope and some Perl. More and more often I find that the applications
demanded by the customers grow and get more complex.
Looking for alternatives I downloaded and tested Struts and Tapestry.
I found out that both frameworks fail to correctly (client-side)
validate form input in Internet Explorer. And I used the example forms
provided with these frameworks!
I quite can't understand why something like that can happen in a release
version? A framework that does not support IE correctly is useless in a
real world envirnonment. Internet Explorer is the most used browser out
there.
This is not about the pros and cons of this and that browser. This is about
usability.

AW: automatic form validation not available in IE - again
Posted by Andy Pahne <ap...@big1.de>.
Changing the properties file is one good idea, but the problem also occurs
when I select "English" as locale in the workbench. Although I did that
there are still those strings of the german properties file in the generated
HTML-source.
I'll think about which list to use next time.

Ok, I won't harsh you out for posting this to the -dev list, but it belongs
in the -user list.
The problem is definitely in the quotes. Tapestry doesn't escape quotes in
strings when it generates the dynamic script (there's no way to tell when it
is safe or necessary to do so).
You might try changing your .properties file entry from
foo=blah "Baz"
to
foo=blah \\"Baz\\"
The double slashes will be parsed as single slashes, the end result should
be
return validator_invalid_field(field, "Eingabefeld \"Date Field\" ist ein
Pflichfeld.");
In the browser, which will operate correctly.
It's possible this problem is in the donated German localization of the
validation strings. I never looked at that because I don't read German. I
think Malcom imported it into Tapestry.

hello again
Mr Lewis Ship is right when he complains that my problem description was not
very helpful. Sorry for stealing your time, but I'll correct myself on that
in a minute.
How to reproduce what I called a bug but what also could be a problem with
my environment:
- Install Apache Tomcat/4.1.18 on Win2k Professional Service Pack 3, German
Edition
- deploy Tapestry-2.3-core with Ant
- Open IE 5.0 (plain vanilla install, only proxy configured)
- Open the tutorial
- Start "Workbench"
- Select "Fields" and then;
First Javascript-Error before anything of the page renders:
Line 32, Char 58: ')' expected
Oh, when I look at the source code, line 32:
return validator_invalid_field(field, "Eingabefeld "Date Field" ist
ein Pflichfeld.");
[More javascript errors pop up, but these are not important]
I think there is something wrong with quotes.
I suspect that due to the same bug no client side validation occures in
Mozilla 1.2.1 when I open the same page. No javascript popups, but obviously
no client side validation.
Another side-effect of this bug is that the link to the inspector does not
work properly: you cannot open the Inspector.
I repeated these tests with Tapestry-2.4-alpha-4. Same result.
And err, though a bit off topic: client side validation does not work for me
with Struts either. Javascript errors also. Maybe very stable and "used by
tens of thousands of developers", but obviously not with IE.
No blog found yet to complain...
Bye,
Andy

Betreff: RE: automatic form validation not available in IE
A few weeks ago, I posted a message about abuse of the mailing lists.
This is a perfect example.
The message is posted to the wrong list; it should be posted to
tapestry-user@jakarta.apache.org.
The message is crying out to be ignored. The user is negative, accusatory
and has done no research on the subject matter of his problem.
He doesn't bother to describe his problem: "fali to work correctly" is not a
problem description.
He also has the gaul to accuse not one, but two, released, stable frameworks
used by tens of thousands of developers of being broken in a major, obvious
way. It has never occurred to him that the problem may be with his
environment.
He has not provided any evidence that he spent more than five seconds
digging into his problem.
He has not provided any resources to help us diagnose his problem (though,
with the other problems in the message, I'm not predisposed to dropping my
useful work to help him). Not any info about his environment, version of
IE ... nothing. He's begging us to beg HIM for the information we need just
to get started.
Now, he'll probably find some blog to complain about how useless Tapestry
is, and how mean we all are.
