s:radio and s:checkboxlist - how to customize listValue property.
When I use that 2 components in my form I need to set attributes listValue and listKey. That attributes as I understand require a field of a bean that is a member of collection represented by list attribute. Example: That means: 1) there will be one radiobutton for each element of collection getTypes(). 2) Each html radiobutton will have value = getId() and label = getName() . I want to compose label from several fields of my bean. So I can't write because that class doesn't have getSomeField() method. How can I do this ? -- View this message in context: http://www.nabble.com/s%3Aradio-and-s%3Acheckboxlist---how-to-customize-listValue-property.-tp22455829p22455829.html Sent from the Struts - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
Re: s:radio and s:checkboxlist - how to customize listValue property.
The easiest (I'm not going to say "best") solution is to make a "fake" getter on your bean. Make a "getListLabel()" method that composes a String from the values that you want to display in the list label, and then set the listValue to be "listLabel". This is the way I've done this in the past and it works OK. It isn't ideal if you want to keep your model carefully isolated from your UI but my own designs are a little less pure than that. jk On Wed, Mar 11, 2009 at 10:05 AM, boraldo wrote: > > When I use that 2 components in my form I need to set attributes listValue > and listKey. > That attributes as I understand require a field of a bean that is a member > of collection represented by list attribute. > > Example: > > listKey="id" /> > > That means: > 1) there will be one radiobutton for each element of collection getTypes(). > 2) Each html radiobutton will have value = getId() and label = getName() . > > I want to compose label from several fields of my bean.

>> It isn't ideal if you want to keep your model carefully isolated from your UI Unfortunately it is the case, so I need another solution.
