Re: DropDownChoice with -1 value
ty Jeremy, but usually we'll get these values from db.
Imagine this, a dropdown of customers, if I do it the way that you said,
using a properties file,
for each new client, what I have to do?
To change that file and It's really bad if you have many inserts.
About my trouble, to see what I mean just do an update on data that fills
any dropdown putting a negative value on id.
something like this:
customer_id = -1
thanks.

If you create a properties file for the page class and use dot notation
matching your page hierarchy but leave the last value as null you can set
the default value:
For example:
theForm.birthdayMonth.null=M
theForm.birthdayYear.null=Y
theForm.birthdayDay.null=D
See if that helps..

Hello Everybody
I'm using wicket.markup.html.form.DropDownChoice and it
works fine until now, when I got a suspicious behavior
Into database I have one data called "TEMP CUSTOMER" that has
id = -1 (it's business logic of our client, that data came through
database importation, and I can not update that data)
Following my code:
List relations = relationManager.list();
final DropDownChoice ddRelations = new DropDownChoice("relation", (
task.getRelation() == null) ? new Model() : new
Model(task.getRelation()),
relations, new IChoiceRenderer() {
public Object getDisplayValue(Object object) {
return ((Relation) object).getName();
}
public String getIdValue(Object object, int index) {
return String.valueOf(((Relation) object).getId());
}
});
form.add(ddRelations);
and HERE is the source code generate on html :
Choose one
TEMP CUSTOMER
CUSTOMER 1
CUSTOMER 2 .. and so on ...
As you can see, there are two options with selected attribute,
therefore always "TEMP CUSTOMER" will be selected.
When I saw this, I though why in all other dropdownchoices
that I had already implemented following the same sample are working very
well ?
I had no doubts, and I changed the TEMP CUSTOMER id
on database to "1" and ... sup.. the dropdownchoice works fine.
But I can't change that data, so I rollback, and also the
problem rollback.
I ask to you , experts guys, if I put a negative value into a
dropdownchoice, it will be the default value if none is selected ?
How I can do "Choose one" be the default value in this specific case ?
Any idea to solve this problem ?
Thank you

DropDownChoice with -1 value
Hello Everybody
I'm using wicket.markup.html.form.DropDownChoice and it
works fine until now, when I got a suspicious behavior (maybe bug)
Into database I have one data called "TEMP CUSTOMER" that has
id = -1 (it's business logic of our client, that data came through
database importation, and I can not update that data)
Following my code:
List relations = relationManager.list();
final DropDownChoice ddRelations = new DropDownChoice("relation",
(task.getRelation() == null) ? new Model() : new Model(task.getRelation()),
relations, new IChoiceRenderer() {
public Object getDisplayValue(Object object) {
return ((Relation) object).getName();
}
public String getIdValue(Object object, int index) {
return String.valueOf(((Relation) object).getId());
}
});
form.add(ddRelations);
and HERE is the source code generate on html :
Choose one
TEMP CUSTOMER
CUSTOMER 1
CUSTOMER 2 .. and so on ...
As you can see, there are two options with selected attribute,
therefore always "TEMP CUSTOMER" will be selected.
When I saw this, I though why in all other dropdownchoices
that I had already implemented following the same sample are working very well
?
