Hello
You are generating Select filed by
t.getBeanHandler().getFormBuilder().generateField(
t,
new ConstrainedProperty( "friendTypeId" ).inList( identifiers ),
null,
"" );
in printForm function.
When you regenerate the form if !friend.validate() , then
generateForm(template, friend ),
regenerate all form fields. So the list is overwrites by this.
Followings are the 2 solutions may be adopted. I recommend second.
Solutions 1)
// is oke
printForm( friendTypeList, template );
print( template );
// select list not generated (i.e. empty)
if ( !friend.validate() ) {
generateForm( template, friend );
printForm( friendTypeList, template );
print( template );
}
Solutions 2)
// is oke
String[] identifiers = printForm( friendTypeList, template );
friend.addConstraint( new ConstrainedProperty( "friendTypeId" ).inList(
identifiers ));
generateForm( template, friend );
print( template );
// select list not generated (i.e. empty)
if ( !friend.validate() ) {
String[] identifiers =printForm( friendTypeList, template );
friend.addConstraint( new ConstrainedProperty( "friendTypeId" ).inList(
identifiers ));
generateForm( template, friend );
print( template );
}
// 'cloned' from a Bamboo example (free source to read is great!!)
public String[] printForm( List<FriendType> friendTypeList, Template t ) {
String[] identifiers = new String[ friendTypeList.size() ];
List<Object[]> labelList = new ArrayList<Object[]>();
for( int i = 0; i < friendTypeList.size(); i++ ) {
FriendType friendType = friendTypeList.get( i );
String friendTypeId = String.valueOf( friendType.getId() );
identifiers[ i ] = friendTypeId;
labelList.add(new Object[] { "friendTypeId:" + friendTypeId,
friendType.getType() } );
}
final Object[][] resources = labelList.toArray( new Object[0][0] );
t.addResourceBundle( new ListResourceBundle() {
protected Object[][] getContents() {
return resources;
}
});
return identifiers ;
}
Regards
