Re[6]: Form bean is not stored in request

No. Before your action is called the form bean exists and its values
are set.

This is definitely the problem.  What properties are you trying to
set?

Re: Form bean is not stored in request

[Nadja Senoucci <Na...@zmnh.uni-hamburg.de>]

Hello,

>This is definitely the problem.  What properties are you trying to
>set?

I have two map backed fields in form. Since they can actually exists
repeatedly I am building the name in my .jsp and am displaying this as
follows:

<tr bgcolor="#FFFFFF"> 
          <% String fname = "field(searchfield"+(counter)+")";
		     String pname = "parameter(searchparam"+(counter)+")";%>
          <td> <html:select property="<%=fname%>"> 
            <html:optionsCollection property="searchFields" value="value"
label="label"/> 
            </html:select></td>
          <td><html:text property="<%=pname%>"/></td>
        </tr>
        <% counter++;
   }while(counter<=number); %>

So, the fields should be set via setField(String key, String value) and
setParameter(String key, String value):

public void setField(String key, String value){
	LoggerSupport.logDebug("setField(): key: "+key+", value: "+value,log);
	this.fields.put(key,value);
	LoggerSupport.logDebug("setField(): sind die Daten auch in der Map?
"+(this.fields.get(key)==null?"Nein":"Ja "+this.fields.get(key)),log);
}

public void setParameter(String key, String value){
	LoggerSupport.logDebug("setParameter(): key: "+key+", value: "+value,log);
	this.params.put(key,value);
	LoggerSupport.logDebug("setParameter(): sind die Daten auch in der Map?
"+(this.params.get(key)==null?"Nein":"Ja "+this.params.get(key)),log);
}

The Maps are being initialzed in SuchenForm's contructor:

public SuchenForm(){
	fields = new TreeMap();
	params = new TreeMap();
	cnt = new Integer(1);
}

Greetings,
Nadja
