I need to solve this issue.
I am using jsf primefaces with c:foreach here is my code. but this code is not running.
<p:tab id="catagoryTab" title="#{hardvalue['tutor.reg.tab2']}">
<p:panel header="#{hardvalue['tutor.reg.tab2']}" id="rowCreator">
<h:outputLabel value="#{hardvalue['tutor.reg.selectStmt']}"></h:outputLabel>
<h:panelGrid columns="3" style="width:100%;">
<p:outputLabel value="#{hardvalue['tutor.reg.category.table.collection']}"/>
<p:outputLabel value="#{hardvalue['tutor.reg.category.table.level']}"/>
<p:outputLabel value="#{hardvalue['tutor.reg.category.table.subject']}"/>
</h:panelGrid>
<c:forEach begin="0" end="#{Registerbean.size -1}" varStatus="loop" var="row">
<h:panelGrid columns="3"
style="width:100%; border: 1px solid #d4f1ff; border-radius: 3px 3px 3px 3px; background:#F7FDFF 50% 50% repeat-x ;">
<p:selectOneMenu
value="#{Registerbean.selectedtutorialType[loop.index]}"
style="font-size:15px !important; width:100px;">
<p:ajax process="#this" update="levellist1_#{loop.index}, levellist2_#{loop.index}, subjectlist_#{loop.index}" event="change"
listener="#{Registerbean.updateRecords(loop.index)}" />
<f:selectItem itemLabel="#{hardvalue['tutor.tutorial']}"
itemValue="tutorial" />
<f:selectItem itemLabel="#{hardvalue['tutor.conversaion']}"
itemValue="conversation" />
<f:selectItem itemLabel="#{hardvalue['tutor.music']}"

itemValue="other" />
</p:selectOneMenu>
<h:panelGrid columns="3" >
<p:selectOneMenu style="width:230px" id="levellist1_#{loop.index}" value="#{Registerbean.selectedtutorialLevelFrom[loop.index]}"

<f:selectItems value="#{Registerbean.levellist}" />
</p:selectOneMenu>
<p:outputLabel value=" #{hardvalue['tutor.reg.to']} " />
<p:selectOneMenu style="width:230px" id="levellist2_#{loop.index}" value="#{Registerbean.selectedtutorialLevelTo[loop.index]}"

<f:selectItems value="#{Registerbean.levellist}" />
</p:selectOneMenu>
</h:panelGrid>
<p:selectOneMenu id="subjectlist_#{loop.index}" value="#{Registerbean.selectedtutorialSubject[loop.index]}"
style="width:230px;"
label="#{hardvalue['tutorsearch.select']}" filter="true" filterMatchMode="startsWith"
panelStyle="width:383px">
<f:selectItems value="#{Registerbean.subjectslist}" />
</p:selectOneMenu>
</h:panelGrid>
</c:forEach>
<p:commandButton id="moreButton" value="#{hardvalue['tutor.reg.addmore']}" update="rowCreator" process="#this" actionListener="#{Registerbean.addNewRow}" />
</p:panel>
</p:tab>
The above code is a tab in wizard. So I need to move on the next page after this one.
But I am not able to get the values as it do not let me assign to the array variables using indexes. Here is my backingbean
bean name: #ManagedBean(name="Registerbean")
private Tutor tutor= new Tutor();
private String[] selectedtutorialType= new String[size];
private String[] selectedtutorialLevelFrom= new String[size];
private String[] selectedtutorialLevelTo= new String[size];
private String[] selectedtutorialSubject= new String[size];
public void addNewRow(){
System.out.println("In add row");
size++;
selectedtutorialSubject=selectedtutorialLevelTo= selectedtutorialLevelFrom=selectedtutorialType=new String[size];
}
Here is my flowlistner through which I am just checking about the values of this tab. flowListener="#{Registerbean.onFlowProcess}"
public String onFlowProcess(FlowEvent event) {
System.out.println("tab id is:"+event.getOldStep());
if(event.getOldStep().equalsIgnoreCase("catagoryTab")){
for(int i=0;i<selectedtutorialType.length;i++){
System.out.println("selectedtutorialType : "+selectedtutorialType[i]);
System.out.println("selectedtutorialLevelFrom : "+selectedtutorialLevelFrom[i]);
System.out.println("selectedtutorialLevelTo : "+selectedtutorialLevelTo[i]);
System.out.println("selectedtutorialSubject : "+selectedtutorialSubject[i]);
}
}
return event.getNewStep();
}
What I want is : I want to draw components. on add row A component line will be added here. first one of the component's value changes, it reflacts the values of other two in that row only. but I is not doing the same. As the next button of p:wizard is not allowing me to move upword.
for updates it uses this function of backing bean.
public void updateRecords(int index) {
System.out.println("In update records: "+index);
levellist = new ArrayList<String>();
if (selectedtutorialType[index].equals("tutorial")) {
subjectslist = Arrays.asList(tutorialSubject);
levellist = Arrays.asList(tutorialLevel);
System.out.println("tutorial selection done..");
return;
} else if (selectedtutorialType[index].equals("conversation")) {
subjectslist = Arrays.asList(conversationSubject);
levellist = Arrays.asList(conversationLevel);
System.out.println("Conversation selection done..");
return;
} else if (selectedtutorialType[index].equals("music")) {
subjectslist = Arrays.asList(musicSubject);
levellist = Arrays.asList(musicLevel);
System.out.println("Music selection done..");
return;
} else {
subjectslist = Arrays.asList(otherSubject);
levellist = Arrays.asList(otherLevel);
System.out.println("Other selection done..");
return;
}
}
What to do. Plz help. Any other detail for this, if I am missing, let me know.
Thanks
