Help!! TextField in ListView = NULL
Hi,
I am very new with wicket and I have a problem with TextField within
ListView , I try to getModelObject from the Textfield but return NULL ?
I am trying my best to find the solution, unfortunately I am running out of
time with my final project. Already spent 2 days dealing with this small
problem :,(
Hope you guys can help. Below is the some part of the codes:
textfieldModel = new Model("");
textField = new TextField("textfield",textfieldModel );
listItem.add(textField);
listItem.add(saveLink = new Link("saveLink") {
public void onClick() {
String myText = (String) textField.getModelObject();
info("####### myText = "+myText );
}
});
Thanks!!

Re: Help!! TextField in ListView = NULL
Posted by Al Maw <wi...@almaw.com>.
Have you done any web development before using Wicket?
If so, you should be able to solve this problem by asking yourself the
following questions:
What happens if you click a link on a web page?
Do you think the browser sends the data in a text field on the page to
the server if you click a link?
What about if you put the <input> tag in a <form> and click a link?
What about if you put the <input> tag in a <form> and click a submit button?
In short, I'd suggest thinking a little more about the fundamentals
before playing around with user input in listviews. Have a look at the
examples.
Alastair
P.S. There are ways to do what you're trying to do without needing to
put things in a form, etc., but they involve AJAX and therefore
probably aren't the best solution for whatever it is you're trying to
do.

Re: Help!! TextField in ListView = NULL
Posted by Alvin_my <al...@gmail.com>.
I have add testsListView.setReuseItems(true), but still doesn't work.
:confused: Hope anyone able to give me hints and guide me to the correct
implementation... thanks
Refer to "HERE" below:
ListView testsListView = new ListView("tests", tests) {
public void populateItem(final ListItem listItem) {
final Test myTest = (Test) listItem.getModelObject();
final Link editLink1;
listItem.add(editLink1 = new Link("editLink") {
public void onClick() {
Long test_id = myTest.getTest_id();
TestCanvas testCanvasPage = new TestCanvas(test_id);
setResponsePage(testCanvasPage);
}
});
editLink1.add(new Label("title", myTest.getTitle()));
String test_dateNow = df.format(myTest.getTest_date());
listItem.add(new Label("date", test_dateNow));
listItem.add(new Label("time", myTest.getTest_time()));
listItem.add(new Label("duration",
myTest.getTest_duration()));
listItem.add(new Label("status", myTest.getStatus()));
HERE --> testMeModel = new Model("");
testMeField = new TextField("testMe",testMeModel);
listItem.add(testMeField);
Lecturer lecturer =
getQuestionnaireService().getLecturer(myTest.getLecturer().getLecturer_id());
String lecturerName = lecturer.getPrintableName();
listItem.add(new Label("creator",lecturerName));
final Link removeLink = new Link("remove"){
public void onClick() {
getQuestionnaireService().removeTest(myTest);
TestManager testManagerPage = new TestManager();
setResponsePage(testManagerPage);
}
};
listItem.add(removeLink);
removeLink.add(
new JavascriptEventConfirmation(
"onclick",
"Delete test of " +
myTest.getTitle() +
" on " +
myTest.getTest_date()+
", time " +
myTest.getTest_time()+
" ? "
)
);
final Link testMeLink;
listItem.add(testMeLink = new Link("testMeLink") {
public void onClick() {
HERE --> String test_Me2 = (String) testMeField.getModelObject();
System.out.println("#########################");
System.out.println("####### test_Me = "+test_Me2);
System.out.println("#########################");
info("####### test_Me = "+test_Me2);
}
});
}
};
HERE --> testsListView.setReuseItems(true);
border.add(testsListView);
