Hi, iam new to wicket, am going through the available examples, i dont
understand how can i capture the selected option in a drop down choice in
the wicket? I checked the example tutorial given in the ensode.net but
still i dont understand how to capture the selected value of the drop down
and
First of all, let me tell you that, I am also fairly new to Wicket. However here are my two cents.
Wicket experts - Please correct me if I am wrong.
How are you sending the data to the page? Are you using any model? If you are, you can retrieve the data using the model object. If not, I think
About the dropdown:
Use a model, maybe a property model to hold the selected dropdown object.
Property models require that there are a get and setter method for the supplied
property. You could also use the abstractmodel and implement your own thing, if
per say you needed to update something
As well as what the others have said, take a look at the wiki,
specifically
http://www.wicket-wiki.org.uk/wiki/index.php/DropDownChoice_Examples,
which might help.

Select/Combo is just as another input field. The model behind the Combobox will hold the selected value.Hidden field: See HiddenField componentBut the question is why do you need it? Normally in wicket there is no need for a hidden field to store data.

Thanq Nino,
well, iam using a model to store the data , actually i was going through the
example given in the http://ensode.net/wicket_first_look.html , where in the
author creates two models , the first model to store the normal form values
and the second model explicitly to store the dropdown
Hi Sathya
Yes you should use one model for each of your dropdowns.
Lets say you are creating a site where you can search for books.
Then you might have a drop down for author and maybe category.
I guess(without knowing anything about searching and or books:)) that I would
create a class that

Hmm - should isn't really correct - could, yes, but not should.
Personally, I'd suggest a single CompondPropertyModel, set for the
form, if not the page, as that can really cut down on the code you
need to write.
That also solves where to put any associated data, as the ModelObject

true, I was meerly trying to explain that you really dont have to grab the
selected object, as this is what wicket does for you:)
I havent yet worked with compoundProperty models...

Hi everyone,
I have the following problem:
I supply the DropDownChoiceElement with a List containing HashMap's. So
every Listelement is a HashMap. The HashMap contains a association
between ID's and Names (the ID's are primary key whereas the Names are
not). Don't bother about the problem that
I succesfully manage to create the html-code right, thru suppling an
IChoiceRenderer. However: how do I get the selecte Value-ID from the
DropDownChoice-Element. All I manage to get is a String containing the
Name and the ID.
Typically, you should do that via your model. The drop down

It doesn't work in firefox because you placed the form directly to table.
This is not valid and firefox freaks out. You have to put it in table cell
(wrap the form in trtd and /td/tr)

For 1.2 you have to use the wicket_1_2 branch.

Okay that's fine. We were using the 1.2.1 release jars and not from SVN. So
is it okay if i check out from wicket_1_2_1 branch instead of wicket_1_2
branch?

if you update to latest code from svn *wicket_1_2 branch*
no, wicket_1_2_1 branch was a mistake - it is supposed to be a label that marks the code that went into 1.2.1 release not a branch - but maven made a booboo.frank i thought you were gonna move it to tags?
