[TYPO3-seminars] use checkboxes field as radiobutton or select listbox

[David Denicolo]

I think the problem is inside the html code, with checkboxes I have
tx_seminars_pi1_registration_editor[checkboxes][0]
tx_seminars_pi1_registration_editor[checkboxes][1]
with radiobutton and select i have
tx_seminars_pi1_registration_editor[checkboxes]

here the code:

with checkboxes renderlet:RADIOBUTTON
   <input type="checkbox" 
name="tx_seminars_pi1_registration_editor[checkboxes][0]" 
id="tx_seminars_pi1_registration_editor_checkboxes_0" value="3">
   <label 
for="tx_seminars_pi1_registration_editor_checkboxes_0">Teilnehmer</label><br>
   <input type="checkbox" 
name="tx_seminars_pi1_registration_editor[checkboxes][1]" 
id="tx_seminars_pi1_registration_editor_checkboxes_1" value="4">
   <label 
for="tx_seminars_pi1_registration_editor_checkboxes_1">Arbeitgeber</label>


with renderlet:RADIOBUTTON
   <input type="radio" 
name="tx_seminars_pi1_registration_editor[checkboxes]" 
id="tx_seminars_pi1_registration_editor_checkboxes_0" value="3">
   <label 
for="tx_seminars_pi1_registration_editor_checkboxes_0">Teilnehmer</label>
   <input type="radio" 
name="tx_seminars_pi1_registration_editor[checkboxes]" 
id="tx_seminars_pi1_registration_editor_checkboxes_1" value="4">
   <label 
for="tx_seminars_pi1_registration_editor_checkboxes_1">Arbeitgeber</label>


with renderlet:LISTBOX
<select name="tx_seminars_pi1_registration_editor[checkboxes]" 
id="tx_seminars_pi1_registration_editor_checkboxes">
   <option value="3">Teilnehmer</option>
   <option value="4">Arbeitgeber</option>
</select>
