Form bean is not stored in request
Hello everyone, I have this weird little problem and I don't know how to fix it. I have a form (actually I have many forms but the others work just fine) and a form bean and action class for it. Now when the form gets processed (after hitting 'submit') its form bean should get stored in the request. But it isn't for some reason. When the action class now tries to access this form bean, it can't find it in the request and creates a new one - which results in exceptions since it doesn't have the data the form bean should've had. Any ideas why? I've checked the action mapping, it is set to request and there is an attribute defined for the form bean. I know the form does not get stored in the request since that would usually be logged in my log file (it gets logged for all the other forms, anyway) but there is no such entry for it. I would include code with this email but I have no idea where the error might be and I don't want to post all of the code of those two classes, the form and the action mapping for it, since that would be way too much code, I fear... If you could tell me what you need to look to find out where the error is, I'll send it in - and I'd greatly appreciate any kind of help. This error is slowly driving me crazy...

Re: Form bean is not stored in request
Hello again,
it is actually struts that seems to be expecting the form bean in the

Re: Form bean is not stored in request
hi,
change the scope to session , just to track down the problem.
also make sure u have properly defined the form-bean== suchen
to SuchenForm in the config
remove attribute "attribute" in the action mapping if not
needed

Re: Re[2]: Form bean is not stored in request
Hello again,
Do you need the above line for some good reason. If not, drop it.
I deleted the attribute line. Stupid easy-struts is still telling me that
attribute=suchen but I can't find the line the struts-config.xml anymore. I
have that line in all my action mappings (for forms anyway), it never did
anything... Why shouldn't I have the line in there?
Still things seem to be behave oddly... Here's the logging (with comments
from me) I don't quite understand what is going on anymore...
1) Looking for ActionForm bean instance in scope 'request' under attribute
key 'suchen'
2) Creating new ActionForm instance of type 'de.zmnh.struts.form.SuchenForm'
This is the first call to the form, it correctly creates a new instance.
Then comes some general struts initialisation. Next 16 lines are from my
own debugging info for the dropdown in my form and then follows some more
struts message initialisations and such. All these are not really of
consequence here, so I deleted them.
Then after info in entered into the form and submit is pressed:
3) Get module name for path /suchen.do
4) Module name found: default
5) Processing a 'POST' for path '/suchen'
6) Looking for ActionForm bean instance in scope 'request' under attribute
key 'suchen'
7) Creating new ActionForm instance of type 'de.zmnh.struts.form.SuchenForm'
8) -- [EMAIL PROTECTED]
As you can see, the form bean is stil being looked for even though I
deleted that line. Maybe, it's easy-struts messing things up but I checked
the code the line is not there anymore...
(mapping: action
input=/index.jsp
name=suchen
path=/suchen

Tried switching to session, no change...)
9) Storing ActionForm bean instance in scope 'request' under attribute key
'suchen'
Now, it created a new one and stores this one in the request right away...

12) setProperty([EMAIL PROTECTED], field(searchfield1),

13) Skipping read-only property

works, but not here...

was created the size of this map is of course zero...

The form's data needs to be processed further in the action and NS that can't really be done if there is a new form bean getting created in NS the action class every time... Or am I completely misunderstanding NS something here? No. Before your action is called the form bean exists and its values are set. NS Also, I've added another line of debugging info and it seems that my NS variables don't get filled at all, meaning my setField and setParameter NS methods do not get called to. I have write debug info into my logfile NS there, so that should get printed into the logfile if they were called... NS Also, there are these lines that are worrying me: NS setProperty([EMAIL PROTECTED], field(searchfield1), NS [string_Geraet.Hersteller]) NS Skipping read-only property NS setProperty([EMAIL PROTECTED], NS parameter(searchparam1), [HP]) NS Skipping read-only property NS I never said anything about read-only. I guess, that's actually my whole NS problem (not sure though) but I have no idea how to fix it. This is definitely the problem. What properties are you trying to set?

Re: Form bean is not stored in request
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=#FF
% 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
tdhtml: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

Hello Nadja, try to change your getters (Field/Param) to return String, not Object.
