Only the first TextField in a repetition gets correct OnChangeAjaxBehavior with 1.5.1
Hi,
Upgrading to wicket 1.5.1 from 1.4.18 my ajax updates stopped working.
I have a page with a form. Inside the form there is a repetition (ListView) that among other things creates a text field for each item (ListItem). Each of those text fields has an OnChangeAjaxBehavior set that should update a label. The label should continously display the total sum of the numbers in the text fields.
With wicket 1.4.18 (and previous versions) this worked fine.
With 1.5.1 only the first text field in the repetition gets the correct ajax behavior - it works the way I want it, and the way it worked with 1.4.*. The other text fields are "dead", except for focus set/removed. While typing in any of the other text fields nothing is updated (the ajax debug window shows no activity). When focus is removed I get a NullPointerException regardless of what I've changed.
Is this a (known) bug, or is there a difference between 1.4 and 1.5 that I've missed?

Hi,
can you attach the code you use to initialize ListView?

I've tried to reproduce your condition in a quickstart. The Java code is
the following:
List<String> itemList = Arrays.asList(new String[]{"red", "blue",
"green", "yellow"});
final Label label;
add(label = new Label("label", ""));
label.setOutputMarkupId(true);
ListView<String> colors = new ListView<String>("colors", itemList){
@Override
protected void populateItem(ListItem<String> item) {
String value = item.getModelObject();
final TextField text;
item.add(text = new TextField("value", Model.of("")));
text.add(new OnChangeAjaxBehavior(){
@Override
protected void onUpdate(AjaxRequestTarget target) {
target.add(label.setDefaultModelObject(text.getModelObject()));
}
});
}
};
colors.setOutputMarkupId(true);
colors.setReuseItems(true);
add(colors);
and the markup is
<body>
<div id="hd">
<div id="logo">
<img src="logo.png" width="50px" height="50px" alt="Wicket Logo" />
<h1>Apache Wicket</h1>
</div>
</div>
<span wicket:id="label"></span>
<div wicket:id="colors">
<input type="text" wicket:id="value"/>
</div>
</body>
However I didn't notice any problem, it works as expected. Maybe the
problem is inside one of your custom components (ContextLabel,
ContextTextField, ...)

This is what I love about Wicketeers. They don't just sit around
complaining about something; they jump in and help fix it! Way to go

Solved: Only the first TextField in a repetition gets correct OnChangeAjaxBehavior
with 1.5.1
Posted by Anders Peterson <ap...@optimatika.se>.
The problem was in the html file.
I used to have this:
<input name="marketWeight" type="text" id="marketWeight" size="6" maxlength="6"
wicket:id="marketWeight" />
Needed to change that to:
<input type="text" size="6" maxlength="6" wicket:id="marketWeight" />
"marketWeight" is the component with the ajax behaviour, and it was in a
ListView so I had several of them.
I guess something related to replacing the name/id of a component changed from
1.4 to 1.5.

Hello again, I still have this problem... (been working on other things)
I've tracked the problem back to the request parameters simply not containing
the expected values.
This "input name" seems correct since I changed the market weight attribute of
the second instrument:
instruments:1:marketWeight
But the HashMap containing parameter values ONLY contain this:
{instruments:0:marketWeight=[17.602]}
This results in me getting null as FormComponent input.
Anyone know what I've done wrong?
