Re: Can Wicket automatically remove beginning and trailing spaces in a text field?
Just one question... on method protected void convertInput() I
see convertValue(getInputAsArray()) is only called if typeName==null,
otherwise IConverter is used. It is always guarantied that "trim" behavior?
Thanks for your explanations and time!

No fuss, just confusion. Thanks for the clarification, which helps not only to

Re: Can Wicket automatically remove beginning and trailing spaces in a text field?
Not sure what the fuzz is all about: wicket trims the whitespace
before and after the input by default (like Marat already mentioned in
this thread).
Marat's code example is taken *directly* from Wicket's FormComponent.
You don't have to do anything.

Re: Can Wicket automatically remove beginning and trailing spaces in a text field?
For this to work, I have to overwrite this method either for each form or write
a custom class extending FormComponent. Correct?
If yes, then it is not what I hope to get. I dont want to do it for each form
or a custom class.
I came from Spring MVC camp. This task is very easy in Spring.

Re: Can Wicket automatically remove beginning and trailing spaces in a text field?
Why use aspects for 2 when you have IComponentInstantiationListener? All you
have to do is set you components model to use the TrimmingModel pasted
before on the listener. I didn't try it myself but I guess that should work.

RE: Can Wicket automatically remove beginning and trailing spaces in a text field?
Afaik there is no way to set this behavior by some flag. But
1) You can extend TextField to wrap it's model with model which on
getObject() trim (ie. remove begging and trailing spaces) returning
string if Model's type is Sting (in other cases it doesn't make
sense)... when value is setted into model trimming is done by wicket
(see FormComponent#shouldTrimInput) automatically (in older version you
have to do this manually by overriding FormComponent#convertInput()
method)
2) you can do aspect (AspectJ?) to do the same as 1) - with aspect there
is no need to make new class of TextField's type so there is no need to
change the code base...
3) you can override implementation of coverters
override Application#newConverterLocator() to
protected IConverterLocator newConverterLocator() {
ConverterLocator locator = new ConverterLocator();
locator.set(String.class, new IConverter() {
public Object convertToObject(String value,
Locale locale) {
return convertToString(value,
locale);
}
public String convertToString(Object value,
Locale locale) {
return value.toString().trim();
// see trim() which remove trailing and beginning spaces
}
});
return locator;
}
I didn't test it but you've got the idea... But this solution is really
bad, because if you want to turn off this behaviour (trimming) in some
cases
you can't do it without overriding for example Component#getConverter()
to convert it in default way and it's a mess.
I recommend you to trim it by hand on Model level (make some wrapper
model to do it so) or on tier (layer) where you obtain data (data acces
layer? service level?). It depends on if spaces have some business
meaning. If yes do it on model level otherwise on that layer.

It already does that.
FormComponent:
protected T convertValue(String[] value) throws ConversionException
{
return (T)(value != null && value.length > 0 && value[0] != null ?
trim(value[0]) : null);
}

Re: Can Wicket automatically remove beginning and trailing spaces in a text field?
Never done it myself, and don't know if it is a better way to do it, but:
protected IConverterLocator
{
return new ConverterLocator();
}
can be overriden to return your own converter locator and... plug there a
default converter (for Strings?) that will trim strings...
If you want to do this for a particular kind of component, e.g. textareas,
another possibility would be to use a component instantiation listener and
wrap the component model with a trimming model, e.g.
import org.apache.wicket.model.IModel;
import org.apache.wicket.model.Model;
public class TrimmingModel extends Model {
private static final long serialVersionUID = 1L;
private IModel model;
public TrimmingModel(IModel model) {
this.model = model;
}
@Override
public void setObject(String object) {
if(object != null)
this.model.setObject(object.trim());
this.model.setObject(object);
}
@Override
public String getObject() {
return this.model.getObject();
}
}
Best,
Ernesto
