Tiles breaks my page that uses logic:iterate

[Janne Mattila]

I have a simple page for editing some form properties. It works. There's a 
select box, a multibox, single-select select and a text input field. Now I 
tried to "Tiles-ify" it, just using Tiles to add some silly decorations 
around the actual form. Using tiles seems to break the form, the exception I 
get is

       at org.apache.jsp.inputs_jsp._jspService(inputs_jsp.java:57)

the JSP page for the form looks like:
<html:form action="/TilesSaveInputs" onsubmit="return 
validateInputsForm(this);">

 <bean:write name="inputsForm" property="counter" /><br>
 <html:hidden property="counter" />
 <p>Select + optionsCollection:<br>
 <html:select property="selectedChoicesForSelect" multiple="true" size="5">
        <html:optionsCollection property="allChoices" value="key" label="name"/>
 </html:select><br>
 <p>Multibox:<br>
 <!-- THE FOLLOWING BREAKS THE PAGE -->
 <logic:iterate id="choice" name="inputsForm" property="allChoices">
   <html:multibox property="selectedChoicesForMultibox">
     <bean:write name="choice" property="key"/>
   </html:multibox>
   <bean:write name="choice" property="name"/><br>
 </logic:iterate>
 <p>Single select + optionsCollection:<br>
 <html:select property="selectedChoiceForSingleSelect">
        <html:optionsCollection property="allChoices" value="key" label="name"/>
 </html:select><br>
 <p>Plain text field, validated using validator<br>
 e-mail:<html:text property="text"/><br>
 <p>
 <html:link action="/Start.do">Back</html:link><br>
 <p>
 <html:submit/>
</html:form>
The part which breaks the page is the multibox, it's iterator and use of 
iterator's choice object. If I take that part out the page works fine with 
Tiles, I can make the selections etc.

The page works fine also with the multibox as long as I do not use Tiles. 
With tiles I use the same Actions, JSP code for forming the output is 
straight copy-paste, there's no difference with the action definitions in 
struts-config.xml. The only difference is the use of Tiles. I wonder what 
about Tiles causes this to break?
