I have created a listView with method populateList, that fills a list
of customers meetings with the respective manager responsible for each
line according the figure bellow:
Begin End Manager Detail Total

TOTAL ----- 00:12:46
Obs: I'm using scala :-D
Two problems here:
1. When a new new item is created, only the fields (labels) dateBegin and
dateEnd are preserved with previous assigned values, I lost the
values of **Manager** *DropDownChoice* and the **Detail**
*TextField* in last line of the ListItem.
2. **After change** the *DropDownChoice* of after exit from the
*Detail TextField* is needed *update the model* with the respective
value have chosen from each filed.
So the values are kept only for labels, in truth links. Let me show the code:
add(new ListView[Meetings]("listMeetings", listData) {
override protected def onBeforeRender() {
periodTotal = new Period()
super.onBeforeRender()
}
// for populating the listView
def populateItem(item: ListItem[customer]) = {
var customer = item.getModelObject()
item.add(new LinkDate("beginDate", customer))
item.add(new LinkDate("endDate", customer))
val listManagers: java.util.List[Manager] = managerDAO.listManagers
item.add(new DropDownChoice("managerSelection",
listManagers,new ChoiceRenderer[Manager]("name")))
item.add(new TextField("detail"))
/*
* I tried to use the code bellow but it's cause a markups errors too.
* Only the code above display the components without errors.
*/
//val managerSelection = new LinkManager("managerSelection",customer)
//item.add(managerSelection)
//item.add(new LinkDetail("detail", customer))
var period = new Period(customer.beginDate, customer.endDate.get)
item.add(new Label("total", period.toString(getFormatter())))
item.add(new LinkEdit("edit", customer))
}})
The functions bellow work fine for date value and for edit a
respective fields of the line:
private class LinkDate(id: String, customer: Customer) extends
Link[String](id) {
setEnabled(false)
add(new Label("label", new Model[String]() {
override def getObject(): String = {
var result = ""
if (id == "beginDate") {
result = customer.beginDate.toString("dd/MM/YYYY HH:mm:ss")
}
if (id == "endDate") {
result = customer.endDate.get.toString("dd/MM/YYYY HH:mm:ss")
}
return result
}
}))
// ... doing other stuff
}
private class LinkEdit(id: String, customer: Customer) extends
Link[String](id) {
add(new Label("label", new Model[String]() {
override def getObject: String = "edit"
}));
// ... doing other stuff
}
But for DropDown and TextField I tried to do the same and I failed strongly:
// Doesn't work
private class LinkManager(id: String, customer: Customer)
extends Link[String](id) {
val listManagers: java.util.List[Manager] = managerDAO.listManagers
add(new DropDownChoice("managerSelection", listManagers,new
ChoiceRenderer[Manager]("name") {
def wantOnSelectionChangedNotifications() = {
true;
}
def onSelectionChanged(managerSelection: Manager): String = {
// saving model
})
}
}))
// ... doing other stuff
}
// Doesn't work
// Also here I tried to change textFiled for a inline-ajax Editable label
// And I need the behaviour to change model imadiately after change value
private class LinkDetail(id: String, customer: Customer) extends
Link[String](id) {
add(new AjaxEditableLabel("detail", new Model[String]() {
override def getObject(): String = {
// ... doing other stuff
}
}))
}
The piece of corresponding markup is shoewd bellow:
<TR wicket:id="listCustomersMettings">
<TD><a wicket:id="beginDate"><span wicket:id="label"></span></a></TD>
<TD><a wicket:id="endDate"><span wicket:id="label"></span></a></TD>
<TD>
<SELECT wicket:id="managerSelection" name="id"></SELECT>
<BR>
</TD>
<TD><INPUT wicket:id="detail" type="text" name="obs" value="_"/></TD>
<TD wicket:id="total"></TD>
<TD><a wicket:id="edit"><span wicket:id="label"
style="text-align: center"></span></a></TD>
</TR>
I think that is needed a Object, similar to LinkDate, to deal and
store the values for Manager DropDownChoice and for the textField or
AjaxEditableLabel Detail, but I got in trouble to implement them.
Thanks for someone that could help me or give me information about.
