Hello. I'm having trouble making a *select based on CustomTOs.*
I explain myself: I have three entities: - *User*(idUser, name, surname, phone,...) - *Proyect*(idProyect, name, city,....) - *Member*(idMember, idUser, idProyect, ...) I want to* make a select using user.name as label and member.idMember as value.* I took a look to: http://wiki.apache.org/tapestry/Tapestry5HowtoSelectWithObjects Now, I have the following: - *MemberCTO(idMember, name)*, with a public Constructor, and getters & setters for idMember, name -------------------------- On the page (.tml) I have: <div class="field"> <t:label for="memberCTO"/> <span class="entry"> <t:select t:id="memberCTO" model="membersCTO" encoder="membersCTO" value="memberCTO" t:validate="required"/> </span> </div> -------------------------- On the page (.java) I have ... @Persist @Property private memberCTO memberCTO; private GenericSelectModel<memberCTO> membersCTO; public GenericSelectModel<memberCTO> getmembersCTO(){ return membersCTO; } .... void setupRender() { membersCTO = new GenericSelectModel<memberCTO> (memberDao.findUsersInProyect( fase.getProyecto().getIdProyecto()), memberCTO.class, "name", "idMember", _access); } The source code of GenericSelectModel was obtained from: http://wiki.apache.org/tapestry/Tapestry5HowtoSelectWithObjects I try to load the page, and I get an error (you can see it at the end). I debugged the code, and I can say: - membersCTO contains an ArrayList<MemberCTO> with the data obtained form the DB. - GenericSelectModel, establish (at the Constructor): - idFieldAdapter...: PropertyAdarptedImpl..... name='idMember' - labelFieldAdapter: PropertyAdarptedImpl..... name='name' (I think its correct) - List<OptionModel> getOptions() {} (Inside GenericSelectModel class) for (T obj : list) { optionModelList.add(new OptionModelImpl(nvl(labelFieldAdapter.get(obj)), obj)); } Generate an exception. Particularlly: labelFieldAdapter.get(obj) doesnt work: obj: Object[2] (id=438) *[0]** *Long (id=445) value 6 *[1]* "admin" (id=446) count 5 hash 0 offset 0 value (id=447) Exception:
