Re: Generic DAO
Greetings!
I'm no expert at all for this topic but I can't see your problem with
generic DAOs. I wrote a couple of typical database apps and they all use
generic DAOs. Stuff that is unique to an entity is handled by named
queries defined in the entities.
Works great and saves a lot of code to write.

Hourglass during fle upload
Greetings! I'm using Tapestry file upload capabilities to upload some files. Is it possible to replace mouse pointer to something like an hourglass or so to show that system is busy doing stuff?

Reading HTTP headers

Accessing zone form elements
Greetings!
I have a page that has the following structure:
...
The idea: The select list "item" is updated based on the choosen value of
select list "manufactuer". Content for "item" is pulled from a database.
That works fine but now I need to add some javascript that operates on the
"item" select list. After the first update of the zone, the id of the
select list changes to "item_".
Due to this new id the Javascript document.getElementById("item") fails,
for sure.
How can I solve that? Any ideas?

Validator name for numeric fields
Greetings! What's the name of the system validator for numeric fields in a form? One of the fields in my form is of type "Double". Tapestry is intelligent enough to validate that and provide the message "You must provide a numeric value for " if I try to submit with letters. For translating this message I need to know the validators name, and it is not listed under "Available Validators". Any hints?

Global validation messages translation
Greetings!
I need to translate the messages of the standard validators. The Tapestry
documentation reads:
-
Each validator (such as "required" or "minlength") has a default message
used (on the client side and the server side) when the constraint is
violated; that is, when the user input is not valid.
The message can be customized by adding an entry to the page's message
catalog (or the containing component's message catalog). As with any
localized property, this can also go into the application's message
catalog.
-
Since it is quite uncomfortable to add a property file for every page that
uses a standard validator ("You must provide a value for XY"):
Is it possible to override the default message with a translation? I
didn't find info on that (or just did misunderstand existing documentation
;))

George, I have done exactly the same (a drop-down box that filters entries displayed in a grid) - it is very, very easy using a zone and works like a charm.

:-)
Yes, I did, but it now turned out that I tried it the wrong way:
...
@Persist
private Supplier supplier;
@Component(id="form")
private Form form;
It needs to be
@Persist
@Property
private Supplier supplier;
@Component(id="form")
private BeanEditForm form;
My bad, sorry for confusion.

Display textfield dynamically
Greetings! I have a form that display a select list. This list is filled with data from a database query. Now I would like following behaviour but have no clue on how to implement that: I would like to add the option "Other" to the select list. A soon as this option is choosen (without submitting the form), a textfield should appear so that the user can add a value that is not available in the select list. Any hints here how to achieve this? Thanks Markus - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

Sorry, I don't get that :-(
I have the following in my template:
In the Java file:
...
public List getCapacityValues() {
return crudService.findWithNamedQuery(Capacity.ALL);
}
public String getLabel() {
return currentLeistungElement.label;
}
}
...
The possible values for the Radio group are pulled from a database.
Which radio button should already be selected when the form is displayed
(i.e. pre-selected) is pulled from another table. (It's a 1:n relation,
nut I think that doesn't matter here).
Where do I have to do what you did suggest above?

Grid displaying database relation
Greetings! Let me quickly introduce myself: I'm a long-time PHP developer, starting developing PHP back mid of 90s. After a long pause I started with web application again, but this time I had a look onto Tapestry. Even though I'm knowing Java not very well I think that developing apps with Tapestry is a great fun, especially in comparison to that PHP-Scripting I did in the past. OK, now to my first question: I'm developing a app with a database backend, using tapestry-hibernate. Displaying a grid with content from a database table is quite easy and well described, but what's the best approach to display a grid with content from a database table that has relations? I have a list of users, each of them has role. I have the tables 'user' and 'role'. Displaying all users in a grid was easy, but I also want to display the role in the grid. Any hints into the right direction? Thanks Markus - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
