Re: Binding selection boxes to beans in cocoon forms?
Jason, No problem putting this solution on the Wiki, except that I do not know how I could possibly edit the wiki. I think we could add 8 lines or so to the following page: http://wiki.apache.org/cocoon/WoodyDatatypeReference?highlight=%28selection-list%29 Also, please have a look at the Binding Framework documentation. Search for setSelectionList on it. Did anybody manage to build a concrete example using that technique? Would you be able to post some more snippets of it? How are you setting the selected value from the list?

Re: Binding selection boxes to beans in cocoon forms?
Hi,
Managed to solve one of the problems so that the selection list now shows, but
it shows empty.
Still debugging why it shows empty when there is DB data loaded on the bean to
display.
To get the selection list to show:
Hibernate required the method:
public void setRoomType(RoomType roomType) {
as shown below.
But for Cocoon I had to create the following overriden method
otherwise Cocoon would keep throwing:
An Error Occurred
Incorrect value type for data.roomType (expected class java.lang.Long,
got class
br.com.hotelman.datatypes.RoomType).
//overriden method created for cocoon binding
public void setRoomTypeId(Long id) {
}
Also created the corresponding getter,
and then changed the following:
fd:field id=roomTypeId required=true
fd:datatype base=long/
fd:selection-list type=flow-jxpath list-path=roomTypes
label-path=description
value-path=id /
fd:labelRoom type:/fd:label
/fd:field
To use roomTypeId (instead of roomType). And also the
fb:value id=roomTypeId path=roomTypeId/
And
ft:widget-label id=roomTypeId/
ft:widget id=roomTypeId/
Still working on why the selection list displays empty.
Kind regards, ANdre'
