As I use D2W for the first time, I try to understand where and when I can modify EO records before Save..
I found a trick but its only a trick :
in D2WEditPassword
public void setValue(String newValue) {
Siteuser aUser = (Siteuser) new Administrator();
String epwValue = aUser.getEncryptedPassword(newValue);
object.takeValueForKey(epwValue, key);
}
It works fine , I can save a new record with encrypted password...
BUT I am sure that's not the correct way to do that...
In Siteuser.java, I can initialize the EO record with :
public void awakeFromInsertion(EOEditingContext editingContext) {
...
}
I should be able also to modify a value before insertion... using saveChange() or better
using willUpdate() in the EOStateTransition interface from PWO maybe
I am not sure ...

I set values in my D2W components this way:
public void takeValuesFromRequest(WORequest request, WOContext
context) throws NSValidation.ValidationException {
super.takeValuesFromRequest(request, context);
if (isEdit()) {
object().takeValueForKeyPath(value, propertyKey());
}
}
also in this case I'd separate out the encrytion method and call it
directly - so for example I would have in Siteuser.java
public void encryptAndSetPassword(final String password) {
this.setPassword(transformString(password, Cipher.ENCRYPT_MODE));
}
then modify the D2W component to include:
public void takeValuesFromRequest(WORequest request, WOContext
context) throws NSValidation.ValidationException {
super.takeValuesFromRequest(request, context);
if (isEdit()) {
Siteuser user = (Siteuser)object();
user.encryptAndSetPassword(value);
}
}
I'm not sure what specifically is causing your problem without seeing
more code but the above is the way I would've implemented it.

I am trying to use (for the 1st time) D2W to test my EOModel
I have a D2WEditPassword custom component that's doing its job (take
the value in a pwd Txtfield)
D2WEditpassword.java (extends WOComponent)
.....
public String value() {
return (String) object.valueForKey(key);
}
public void setValue(String newValue) {
object.takeValueForKey(newValue, key);
}
.....
I would like this value to be encrypted via the setPassword() in my
Siteuser class before being written to the DB
(as it will be in my WOApp) but I just get the String value in my
DB..... why ? how can I do it ? (hint in doc...)
Thanks erwin
Siteuser.java (extends EOGenericRecord)
.....
public void setPassword(String password){
setCredential(transformString(password, Cipher.ENCRYPT_MODE));
}
....
