Hi Thiago,
Hi!
invoice.
At this point you need to select a customer: you can insert a customer
number, but, if you don't know it, you can press the search button at
the right of the customer number and the system will open a popup
showing you a list of customers.
You can choose one of them, and, after the selection, the popup will
close, and the data of the selected customer will fill in you form.
I was trying to mimic this behavior.
Ok, now I think it's better explained.
What would be your way to do this? May be there is a simpler way, that I
didn't spot, for solving this problem in tapestry?
I'd do what I proposed above.
Tapestry or not, there are basically two ways of doing what you want: 1)
doing an AJAX request that, after the option is selected, rerenders the
form with the corresponding fields filled and 2) use some JavaScript to
copy the values from the listing to the form. 1) can be easily done in
Tapestry using two zones: one around the form, one for showing the options
(list of customers). In the options, you'd have an EventLink which would
have the customer id as its context and its handler would use it to
pre-fill the properties which are bound to the form's search fields. 2) is
very easy if you know *basic* JavaScript. Like this (not tested, not
dynamic, but can be very easily made dynamic):
document.getElementById('address').value =
document.getElementById('address-from-grid').value.
Also, I understand that the fields in the invoice form could be wrapped
in a zone and updated after the selection, but I don't understand how
can I show a popup to the user, allow him to choose the customer, and
get the data back to my form.
Unless you're talking about the much hated browser popups, popups are
merely CSS things. With CSS and a little bit of JavaScript you can make
parts of your page resize, appear or disappear. Anyway, that's outside the
scope of this mailing list.

Re: prefilling password
I've always considered this a bit of a security flaw. Using the javascript
console you can show the password in plain text.
Eg:
alert(document.getElementById('password').value);

This is actually done by the browser, not Tapestry, which never prefills
password fields. I believe you should add autocomplete=false to your form
or password field. More information here:

Re: Working with JPA - Page Requests - Checking if object with id exists - Redirecting if false
Have you read this?
http://jumpstart.doublenegative.com.au/jumpstart7/examples/infrastructure/handlingabadcontext/1
My personal preference is to treat ids that don’t exist, and ids that you are
not authorised to, the same way: display a does not exist” message on the same
page. It will be detected in setupRender() or, if there’s a Form, in
onPrepareForRender(). To keep it simple and consistent you can create an
ExistenceChecker component that you use like this:
t:form t:id=form context=“personId validate=this
t:existencechecker exists=“person name=message:Person-name
:
/t:existencechecker
/t:form
ExistenceChecker could start like this:
public class ExistenceChecker {
/**
* Usually set by testing the entity of interest, eg. exists=“person”
* (which will be true if client is not null); or
* the entity list of interest, eg. exists=evaluations”
* (which will be true if the list is not null and not empty).
*/
@Parameter(required = true)
@Property
private boolean exists;
/**
* This name will be displayed to the user, substituted into the
object-doesnotexist message.
*/
@Parameter(required = true)
private String name;
Here’s my ExistenceChecker.tml:
!DOCTYPE html
html xmlns:t=http://tapestry.apache.org/schema/tapestry_5_4.xsd;
xmlns:p=tapestry:parameter
t:content
t:if test=exists
t:body /
/t:if
t:if test=!exists
div class=alert ${alertClass}
text-center${doesNotExistMessage}/div
/t:if
/t:content
/html

RE: Multiple domains, one webapp
4) You can't use Tapestry's Live Class Reloading on any class in the common JAR (e.g. Tapestry IOC service implementation classes). I think 4) is the biggest downside in a multi-module project. Do you think Tapestry can do a Live Class Reloading of the common JAR included with contributeCoreLibComponentClasses? If this is about Eclipse (I'm not sure about other IDEs, since I haven't used any besides Eclipse for many years), if you have all the projects open at the same time, you can use live class reloading on all of them at the same, and I do this all the time. Really! I am using IntelliJ IDEA Ultimate and NEED this functionality. Today I need to recompile all maven projects and restart jetty for every change to components and JavaScript modules (all resources) in the common JAR.

RE: Multiple domains, one webapp
1) You have to maintain three projects (or a Maven multi-module project if you're using Maven) instead of one. 2) You'll have two different app servers to configure maintain. 3) You'll probably need to maintain database credentials in two different places. 4) You can't use Tapestry's Live Class Reloading on any class in the common JAR (e.g. Tapestry IOC service implementation classes). I think 4) is the biggest downside in a multi-module project. Do you think Tapestry can do a Live Class Reloading of the common JAR included with contributeCoreLibComponentClasses? 5) If you use an automated build server like Jenkins then you'll have to set up and maintain triple the number of jobs. 6) Your build process will be slower and more error prone because you'll often have to build the common JAR before building and deploying you'll have different log files. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

Re: Working with JPA - Page Requests - Checking if object with id exists - Redirecting if false
Just be aware that there are pluses and minuses to doing it in onActivate(). On the plus side, onActivate() is an event handler, so it can control what’s displayed next by its return type. The return type could even be new HttpError(404, Page not found); http://jumpstart.doublenegative.com.au/jumpstart7/examples/navigation/returntypes1 http://jumpstart.doublenegative.com.au/jumpstart7/examples/navigation/returntypes1 On the minus side, it gets called more than you might expect: http://jumpstart.doublenegative.com.au/jumpstart7/examples/navigation/onactivateandonpassivate/3 http://jumpstart.doublenegative.com.au/jumpstart7/examples/navigation/onactivateandonpassivate/3 Geoff On 4 Aug 2015, at 9:51 pm, Thiago H de Paula Figueiredo thiag...@gmail.com wrote: On Tue, 04 Aug 2015 06:15:08 -0300, Poggenpohl, Daniel daniel.poggenp...@isst.fraunhofer.de wrote: Hello everyone, as the subject describes, we are trying to decide when to redirect the user to the error page.

Re: Multiple domains, one webapp
Hi, Many thanks for all of your thoughts on this. I have chosen to go with having a common project as a jar and setting up maven to build this project first and use it as a dependency for the other two. This means i'll be able to put the various entities in there that are shared between both web applications. I am not *too* concerned about live class reloading if it's only for the shared JAR since it will contain mainly only entities and it doesn't take long whilst developing to just hit run again if I can't figure out a better way. I would imagine these entities will remain relatively static throughout the restructing as they are mapped to database tables using hibernate and everything currently works, they are just going to be moved. Another factor in deciding to use this approach is that I have been told we are having one side of the website launch before the other and this division of the projects into separate web apps makes it slightly easier. I'm looking at the documentation at he moment for how to create a jar file for tapestry to use and I intend to use the documentation here: https://tapestry.apache.org/component-libraries.html I did spot that it says clearly at the top: This page has not yet been fully updated for Tapestry 5.4. Things are different and simpler in 5.4 than in previous releases. but i'm going to have to just run with it and find out what those changes are as I go along. I think long term, having them split into two webapps that just share the same model (the database and various entities) makes most sense. In the meantime, whilst making this decision I have been working on the front end, but after a while of reading up I am thinking (for us) this is the best solution. Any light on what the documentation is hinting at with the updates for that page would be fantastic if anyone has any ideas.
