Re: exception with automatic formbean population

Hi,
I'm using arrays of Strings and call all my fields the same name.
It works ok, yet with some arrangements.
For instance I do not want to set an array length, so I do not initialize my
arrays.
And it works ok.
Thanks.
Emmanuel

Hi Emmanuel,

I just checked the example - to get the data out of the form I used an
Array (sorry, the List just the other way to prepare the data for the
form):

Inside the bean:
private String[] para = new String[3];

Inside the Action:
String[] oldParas = infoForm.getPara();

// if you prefer a List do this...
ArrayList newParas = new ArrayList();
for (int i = 0; i < oldParas.length; i++) {
newParas.add(new String(oldParas[i].getBytes("ISO-8859-1"),
encoding));
}

// now iterate through this list or do whatever with it
...

Replace para with value...

But this is just a quick Sunday afternoon solution - there should be a
way to handle a HashMap, too.

Regards,

Berny

population

Thank you for your prompt answer, Bernhard.

It seems that in strutscx-demo.war, your infoformbean is static.
By using Map values, my formbean is dynamic (I can populate dynamically
my
bean with any form -dynamically created with xsl and fields names gotten
on
the fly -).

The only fields and methods in my formbean are :
private final Map values = new HashMap();
public void setValue(String key, Object value);
public Object getValue(String key);

which is enough to retrieve all fields names and values in the Map.
I failed to see how I could replace this mechanism.
Would you explain me how it works without Map in the case of strutscx ?

Thank you very much,
Emmanuel

Hi Emmanuel,

The reason of the error is: XML names cannot contain the character "(".

One solution would be to replace the Map with a List. Check out the
strutscx-demo.war for an respective example. - Maybe there are other
solutions, too. But keep in mind: StrutsCXStandardDocumentBuilder will
try to make XML elements out of the Request's parameter names.

Hope this is of help for you.

Regards,

Berny

Betreff: [Strutscx-user] exception with automatic formbean population

Hi All,

I use a formbean that retrieves information passed in a form, like this
:

public class InfoFormBean extends StrutsCXValidatorForm {
...
private final Map values = new HashMap();

public void setValue(String key, Object value) {
logger.debug("key:"+key);
values.put(key, value);
}

public Object getValue(String key) {

return values.get(key);
}
...
}

##and my form looks like :
<form ...>
<input name="value(key1)"
type="text" />
<input name="value(prop1)"
type="text" /> ...
</form>


##The formbean is populated alright. The associated action is called and
execute is code also.
##But after the action executes its forward to another page, I get the
following exception :

2004-01-10 22:04:02,158 DEBUG - [StrutsCXStandardDocumentBuilder]
CONSTRUCT request Parameter: action = UPDATE
2004-01-10 22:04:02,158 DEBUG - [StrutsCXStandardDocumentBuilder]
CONSTRUCT request Parameter: value(key1) = townname
MonitorFilter::Error: The name "value(key2)" is not legal for JDOM/XML
elements: XML names cannot contain the character "(".
MonitorFilter::A web application object caused an exception
MonitorFilter::org.jdom.IllegalNameException: The name "value(key2)" is
not legal for JDOM/XML elements: XML names cannot contain the character
"(".
at org.jdom.Element.setName(Element.java:217)
at org.jdom.Element.<init>(Element.java:145)
at org.jdom.Element.<init>(Element.java:158)
etc....

##I tried to reset the formbean before doing the forward, but the error
is exactly the same.
I do not need this information (value(key2)) anymore at that time.
How could I get rid of that ?

Thanks in advance.
Emmanuel
