[FLOW3-general] need help with f:form.select

["Christian Müller (FLOW3 Team)"]

Hi Wasko,

I think you have a minor misconception in your approach. Either you 
directly accept the book in your listAction as it is now (and is the 
recommended way) or you accept the idnr, which is I guess a string or 
integer. I would go for accepting the book as your listAction already 
shows. What I don't see are the proper annotations for your action, 
those are needed. If you have them, your form should work this way:

  <f:if condition="{books}">
       <f:form action="detail">
          <label for="book">Book</label><br />
          <f:form.select name="book" options="{books}"
  optionLabelField="name" id="book" sortByOptionLabel="true" /><br />
          <f:form.submit value="Show" />
       </f:form>
</f:if>

Because you actually just want to select one of your books and don't 
edit any book you can directly use the name argument of the select 
viewhelper, because your form doesn't deal with editing an object. This 
way the selected book (UUID) will be given to the detailAction.

Cheers,
Christian
