Hi folks,
I'm new to the list, so forgive me if I'm not respecting Netiquette or
asking off-topics.
I'm trying to render pieces of html using the following syntax:
from struts-config.xml the definition of the form follows:
<form-bean name="canalizzazioneCLDForm"
type="org.apache.struts.validator.DynaValidatorActionForm"> <form-property
name="listaDanneggiati" type="java.util.ArrayList"/>
</form-bean>
into the jsp I wrote (MyBeanContainer has the method getListaDanneggiati()
which returns a ArrayList of beans):
<jsp:useBean id="beanContainer" class="com.mycompany.MyBeanContainer"
scope="session"></jsp:useBean> ............ <html:form method="post"
action="/canalizzazione_cld.do"> <nested:root name="beanContainer">
<nested:iterate property="listaDanneggiati" >
<nested:text styleClass="inputText" property="cognome"/><br/>
<nested:text styleClass="inputText" property="nome"/><br/>
<nested:iterate property="oggColpiti">
<nested:text styleClass="inputText"
property="descrizioneGenerica"/><br/>
<nested:text styleClass="inputText"
property="tipoGenerico"/><br/> </nested:iterate>
</nested:iterate>
</nested:root>
</html:form>
The html I actually get is:
...............
<input type="text" name="listaDanneggiati[0].cognome" value="SDFSDFDS"
class="inputText"><br/> <input type="text" name="listaDanneggiati[0].nome"
value="SDFSDF" class="inputText"><br/> <input
type="text" name="listaDanneggiati[0].oggColpiti[0].descrizioneGenerica"
value="Trasportato" class="inputText"><br/> <input
type="text" name="listaDanneggiati[0].oggColpiti[0].tipoGenerico"
value="Persona" class="inputText"><br/> <input
type="text" name="listaDanneggiati[0].oggColpiti[1].descrizioneGenerica"
value="COSE" class="inputText"><br/> <input type="text"
name="listaDanneggiati[0].oggColpiti[1].tipoGenerico" value="Cosa/Animale"
class="inputText"><br/> <input type="text"
name="listaDanneggiati[1].cognome" value="SDFSDF" class="inputText"><br/>
<input type="text" name="listaDanneggiati[1].nome" value="SDFSDF"
class="inputText"><br/> <input type="text"
name="listaDanneggiati[1].oggColpiti[0].descrizioneGenerica"
value="Trasportato" class="inputText"><br/> <input
type="text" name="listaDanneggiati[1].oggColpiti[0].tipoGenerico"
value="Persona" class="inputText"><br/> <input
type="text" name="listaDanneggiati[1].oggColpiti[1].descrizioneGenerica"
value="SDFSFSDF" class="inputText"><br/> <input
type="text" name="listaDanneggiati[1].oggColpiti[1].tipoGenerico"
value="Cosa/Animale" class="inputText"><br/> ...............
which is nice but not satisfying. I'd like to get something like:
<input type="text" name="beanContainer.listaDanneggiati[0].nome"
value="SDFSDF" class="inputText"><br/>
where the name property of the input text includes the root name, ie
"beanContainer".
I need this to manage the interactivity correctly. Infact what I actually
get when I submit the form is the following:
java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
at java.util.ArrayList.RangeCheck(Unknown Source)
at java.util.ArrayList.get(Unknown Source)
at org.apache.struts.action.DynaActionForm.get(DynaActionForm.java:298)
at
org.apache.commons.beanutils.PropertyUtils.getIndexedProperty(PropertyUtils.java:474)
at
org.apache.commons.beanutils.PropertyUtils.getIndexedProperty(PropertyUtils.java:428)
at........
Thank you in advance...
