Re: DropDownChoice without preselection and without 'Please choose one'
Hi Johan, hi Martin, Just for the sake of completeness: Having select.null= select.nullValid= as string resources, an empty option is displayed as first item if nullValid is true. If it is false, there is still the 'Please choose one' option. Anyway, I'll stick to the ListMultipleChoice solution I have described before, it might not be the most elegant one, but I think the code is more comprehensive this way. Thanks again for your input on this. Martin Makundi wrote: > > DId you try setting the .null <- property value?

Re: DropDownChoice without preselection and without 'Please choose one'
just had a deeper look at AbstractSingleChoice. looks as if it did exactly this when the ###.null string resource is empty. I will check that out tomorrow.

Re: DropDownChoice without preselection and without 'Please choose one'
Sorry, just saw your message. Didn't know about the .null thing... quite confusing. I will try this tomorrow. Thanks a lot Martin Makundi wrote: > > DId you try setting the .null <- property value?

Solved: DropDownChoice without preselection and without 'Please choose one'
I have found a solution for this after all, not quite elegant, but works like
charm :)
new ListMultipleChoice("select",new Model(new ArrayList(0)), new
PropertyModel(this, "choices"), renderer) {
@Override
protected void onComponentTag(ComponentTag tag) {
super.onComponentTag(tag);
tag.getAttributes().remove("multiple");
}
};
The trick is to use the multiselect component (because this one neither
requires preselection nor nullValid option.
Having an empty list in the model means nothing is preselected.
Since I do not want it to be multi-selectable, I removed the attribute by
overwriting onComponentTag.
Thats it :)

Re: DropDownChoice without preselection and without 'Please choose one'
DId you try setting the .null <- property value? If null is valid then try .nullValid , see http://wicket.sourceforge.net/apidocs/wicket/markup/html/form/DropDownChoice.html ** Martin 2009/2/20 pixologe : > > I tried overriding getDefaultChoice already, returning an empty string, this > did not work, unfortunately. > > The 'Please choose one' option is not rendered, however the first 'normal' > option gets selected instead. > Also, inside AbstractSingleSelectChoice, there remains an empty string in > the options list, letting my ChoiceRenderer stumble when it tries to > interpret my idExpression :( > > If there are any more ideas regarding to this, please let me know. > > Thanks so far! > > btw.: nullValid is the correct 'Please choose one' string resource key > > > > Sergio García wrote: >> >> I guess that if you simply override the dropdownchoice i18n property value >> for that component/page with a plain "" it may work. >> >> DropDownChoice property key for "Please choose one" is "null", or at least >> i remember that. >> >> >> > > -- > View this message in context: > http://www.nabble.com/DropDownChoice-without-preselection-and-without-%27Please-choose-one%27-tp22120191p22120404.html > Sent from the Wicket - User mailing list archive at Nabble.com. > > > - > To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org > For additional commands, e-mail: users-h...@wicket.apache.org > > - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: DropDownChoice without preselection and without 'Please choose one'
I tried overriding getDefaultChoice already, returning an empty string, this did not work, unfortunately. The 'Please choose one' option is not rendered, however the first 'normal' option gets selected instead. Also, inside AbstractSingleSelectChoice, there remains an empty string in the options list, letting my ChoiceRenderer stumble when it tries to interpret my idExpression :( If there are any more ideas regarding to this, please let me know. Thanks so far! btw.: nullValid is the correct 'Please choose one' string resource key Sergio García wrote: > > I guess that if you simply override the dropdownchoice i18n property value > for that component/page with a plain "" it may work. > > DropDownChoice property key for "Please choose one" is "null", or at least > i remember that. > > > -- View this message in context: http://www.nabble.com/DropDownChoice-without-preselection-and-without-%27Please-choose-one%27-tp22120191p22120404.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: DropDownChoice without preselection and without 'Please choose one'
I guess that if you simply override the dropdownchoice i18n property value for that component/page with a plain "" it may work. DropDownChoice property key for "Please choose one" is "null", or at least i remember that. -- View this message in context: http://www.nabble.com/DropDownChoice-without-preselection-and-without-%27Please-choose-one%27-tp22120191p22120391.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
