Replace "Choose one" from DropDownChoice?
Hello, I understand that there must be a solution for this. I googled for some time and found one or two results that seem to match what I am looking but they did not answer my question. Tried myself, not successful. So I want to ask folks here. I have a form and it has a dropdown list. Here are my requirements:
1. Replace "Choose one" with a blank line
2. This blank line is the first option and it is always listed no matter whether a value is selected or not, no matter whether the form field of this dropdown list is required or not.
3. I am using ChoiceRenderer to convert between selection and objects.
4. This behavior is applicable to all DropDownChoice.
How can meet these requirement?
Thanks for your help!
Regards.

It's just a localization property <dropdownchoice-id>.null or
<dropdownchoice-id>.nullValid if that's what you want to change?

Martin,
Very sorry for being confusing to you. Here is what I want:
I want blank line is always there, no matter whether a value is selected or not, no matter whether the field is required or not.
I am using ChoiceRenderer to convert a selected option to objects.
Thanks, David

Posted by Martin Asenov <mA...@velti.com>.
David, please describe the use case in more depths.
1)
You want a dropdownchoice with null selection, which is " "?
2)
You don't want a null selection to be there at all, but show the first element.
Best,
Martin

You have to add a selection choice that is just a blank line option.
This is a typical requirement for any dropdown if you wan the use to
be able to clear their choice.

I tried this one. It works. Summarized what I did based on input from folks here:
1. set null = "" in property file (remove "" properties file)
2. call setNullValid(true) on the DropDownChoice object.
Thanks for help!!!

Also setNullValid(true) otherwise the blank option will disappear once you have made a choice or the model has a value.

I don't understand , Chang...
If you want non selection to be " ", then say
null=" " (without the quotes)
Otherwise if you don't want null selection, you say
component.setNullValid(false); and you're fine

RE: Replace "Choose one" from DropDownChoice?
Posted by Martin Asenov <mA...@velti.com>.
Hi, David!
Let's presume your webapplication class is called WebApp.java. In the same directory where it is present, create WebApp.properties with the following line:
null=
that way every single 'choose one' label will be replaced with "".
P.S. Don't forget to include the props files in the pom as a resource.
Best,
Martin

Subject: Replace "Choose one" from DropDownChoice?
Hello, I understand that there must be a solution for this. I googled for some time and found one or two results that seem to match what I am looking but they did not answer my question. Tried myself, not successful. So I want to ask folks here. I have a form and it has a dropdown list. Here are my requirements:
1. Replace "Choose one" with a blank line
2. This blank line is the first option and it is always listed no matter whether a value is selected or not, no matter whether the form field of this dropdown list is required or not.
3. I am using ChoiceRenderer to convert between selection and objects.
4. This behavior is applicable to all DropDownChoice.
How can meet these requirement?
Thanks for your help!
Regards.
