Thank you, based2.

I am following the jumpstart examples. But in my case, the property I need
to choose from a t:select is not an enum. It`s a complex type.

Official documentation has the easiest way if your situation is not very complex.

https://tapestry.apache.org/using-select-with-a-list.html

For more complex cases (in fact always) I use this component:
https://wiki.apache.org/tapestry/Tapestry5SelectObject

I have added few modifications to it so that it will work even more generic.

For your example with my modification, the component can be used like this:
<t:selectObject
    t:id="selectProduct"
    list="productList"
    value="selectedProduct"
    labelField="literal:productName '\s-\s' price '\s-\s' category.name"
    keyField="literal:productId"
/>

What it will do?



The select list will look like this (look into the labelField)
LG LC51 - $500 - TV
Nokia E71 - $100 - Mobile

For example, let's say that "Products" is a database @Entity and if you have "@Property List<Product> productList" in the background java, and you have "productName" and "price" in each Product, and you have a "@ManyToOne" link to Category (also an @Entity) and you have "name" in "Category". And the behind html values linked to each element will be taken from the primary key of Product (look into keyField). If this is what you want to do, I can send you the code with full modification (our subversion host is down at the moment). Maybe I should post these modifications on the Wiki, but there were some comments that in general this is not a very good approach.
