I wrote a generic selection component that I am using a lot. It is based on someone else's work with the BeanSelectionModel, in Tap 4. It uses Bean Utils.
http://www.phy6.net/wiki/tiki-index.php?page=Tapestry+5+GenericSelectionModel This may help you out some. Another thing I did to make things a bit easier on me, was to make my domain pojo's implement an interface called "Selectable" which forces them to have a method called getLabel() Then I can always specify "label" to the GenericSelectionModel, and the beanutils will call getLabel();. This way I can also aggregate some things into my getLabel() method, like concatenating first and last names, etc. i.e. String getLabel(){ return lastname + ", " + firstname; } On 6/15/07, Erik Vullings <[EMAIL PROTECTED]> wrote:
Hi all, I'm studying the <t:select... > component, which I want to use for populating a select list with products, e.g. the HTML should look like <select ...> <option value="productId1">Product 1</option> etc... I've used it succesfully with a string of names (look at the BlockDemo example in the source code), as well as with an ENUM (look at the PaletteDemo example in the source code), but I actually have a list of products, List<Product>. Each Product in the list has an Id, which should go in the value part of the option, and it's name should be displayed. The simplest approach, it seems, is to use the <t:Loop > component, and create the HTML manually. Or does someone have a good example of how to use the <t:select> component with a List? I've looked at the SelectModel and SelectEncoder parameters of the <t:select> component, but both are interfaces. The first has a SelectModelImpl, which depends on a List<OptionModel>, yet another interface, which has an OptionModelImpl. The SelectEncoder, however, only has an implementation for ENUMs. However, to translate my own List<Product> to a List<OptionModel> does not seem straightforward. Or am I missing something? Could I use type coercion, for example. Any help is appreciated! Erik
