反應我在primefaces的環:不按壓按鈕
<h:form>
<p:ring id="ring" value="#{ringBean.images}" var="image"
styleClass="image-ring" easing="easeInOutBack">
<p:graphicImage value="./../../images/#{image.image}" width="150" height="150"/>
<p:commandButton value="#{image.name}" action="#{image.action}" />
</p:ring>
</h:form>
我RingBean:
@ManagedBean
@RequestScoped
public class RingBean implements Serializable{
private List<PersonImage> images;
private PersonImage selectedPerson;
public RingBean() {
images = new ArrayList<PersonImage>();
images.add(new PersonImage("person3.png", "Pacjent", "patientList"));
images.add(new PersonImage("person4.png", "Admin", "adminList"));
images.add(new PersonImage("person5.png", "Lekarz", "doctorList"));
images.add(new PersonImage("person6.png", "Sekretarka", "secretaryList"));
images.add(new PersonImage("person7.png", "Nieaktywni", "inactiveList"));
}
public List<PersonImage> getImages() {
return images;
}
public PersonImage getSelectedPerson() {
return selectedPerson;
}
public void setSelectedPerson(PersonImage selectedPerson) {
this.selectedPerson = selectedPerson;
}
}
PersonImage類:
public class PersonImage {
String image;
String name;
String action;
public PersonImage() {
}
public PersonImage(String image, String name, String action) {
this.image = image;
this.name = name;
this.action = action;
}
public String getImage() {
return image;
}
public void setImage(String image) {
this.image = image;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAction() {
return action;
}
public void setAction(String action) {
this.action = action;
}
}
面-配置:
<navigation-case>
<from-outcome>adminList</from-outcome>
<to-view-id>/protected/admin/adminList.xhtml</to-view-id>
<redirect/>
</navigation-case>
<navigation-case>
<from-outcome>doctorList</from-outcome>
<to-view-id>/protected/admin/doctorList.xhtml</to-view-id>
<redirect/>
</navigation-case>
<navigation-case>
<from-outcome>patientList</from-outcome>
<to-view-id>/protected/admin/patientList.xhtml</to-view-id>
<redirect/>
</navigation-case>
<navigation-case>
<from-outcome>secretaryList</from-outcome>
<to-view-id>/protected/admin/secretaryList.xhtml</to-view-id>
<redirect/>
</navigation-case>
當我按下我的按鈕,沒有反應。但爲什麼?我加入這個動作按鈕:
而在環我說: images.add(新PersonImage( 「person4.png」, 「管理」, 「adminList」));
action is adminList。爲什麼這不起作用?
當我將按鈕更改爲:<p:commandButton value="#{image.name}" action="adminList" />
一切正常。爲什麼?兩個建築都返回相同的字符
將您的託管bean更改爲'@ ViewScoped',然後重試。 –
