Hi,
is it possible to do the following:
1 Make a deftemplate and inheriting from a dynamic java-bean and in the process adding
some slots.
(This works fine thru what is described in section 2.7.2 (deftemplate
<deftemplate-name> [extends <classname>] [<doc-comment>] [(slot <slot-name> [(default
| default-dynamic <value>)] [(type <typespec>))]*)
2. ASSERT an ordered fact which is an instance of the deftemplate in 1 but which has
all slots, but the ones created in the deftemplate, initialized using an instance of
the java-bean.
Example:
package SE.ericsson.epk.NAM.DataTranscriptGeneratorPackage;
import java.awt.*;
/**
* Java-bean style class to map between a table name and the corresponding
* prefix when setting upp the table in MML.
*/
public class MMLPrefixBean extends java.lang.Object implements Cloneable
{
/**
* Default constructor necessary for a bean.
*/
public MMLPrefixBean()
{
}
/**
* Setter method for the prefix attribute.
*
* @param prefix a three character wide string specifying the prefix to use
when
* configuring the table.
* If a wider string is used as input the prefix will be shortened through cut.
*/
public void setPrefix(String prefix)throws MMLSyntaxException {
String oldValue=getPrefix();
String newValue=null;
if (prefix!=null) {
newValue=new String(prefix.substring(0, 3));
}
if (prefix.length()==3) {
if (oldValue!=newValue) {
this.prefix=newValue;
changes.firePropertyChange("prefix", oldValue, newValue);
}
} else {
MMLSyntaxException MMLExc=new MMLSyntaxException();
this.prefix=newValue;
changes.firePropertyChange("prefix", oldValue, newValue);
throw MMLExc;

newValue);

this.getDescription());
}

MMLPrefixBean copy=null;

copy=new MMLPrefixBean();
copy.setDescription(this.getDescription());
copy.setPrefix(this.getPrefix());
copy.setTable(this.getTable());
}
catch(MMLSyntaxException e) {
System.out.println("Exception in MMLPrefixBean.clone(): ");
}

}

;retrieves a prefix-bean with all attributes set to default values.
(definstance MyExtendedPrefixBean ?anMMLPrefixBean dynamic) ;this leads to the
following error
Jess reported an error in routine DefinstanceList.definstance
while executing (definstance MyExtendedPrefixBean ?anMMLPrefixBean dynamic).
Message: Unknown object class MyExtendedPrefixBean.
Program text: ( definstance MyExtendedPrefixBean ?anMMLPrefixBean dynamic ) at line
23.
(assert ?anMMLPrefixBean) ;this leads to the following error
Jess reported an error in routine Value.factValue
while executing Jess reported an error in routine Variable.resolveValue.
Message: Null context for anMMLPrefixBean..
Message: Not a fact:
"<External-Address:SE.ericsson.epk.NAM.DataTranscriptGeneratorPackage.MMLPrefixBean>"
(type = EXTERNAL_ADDRESS).
I think I understand what I do wrong in both cases but is there a simple possiblility
to assert a fact and have all the field initialized from the bean.
