Problem with
Hi all,
I habe a problem with the element inside a list. If I
add the element to my markup, the design of the list is broken in
firefox and Chrome (windows) during designtime. Runs the markup inside
wicket, everything works.
Here is an example of my Problem. If you open the markup in your
browser, you see that the two lists looks different, although they
should look the same.
ul {
list-style-type: none;
display: flex;
flex-wrap: wrap;
}
li {
border: solid red thin;
width: 25vw;
}
Item 1
Item 2
Item 3
Item 4
Item 1
Item 2
Item 3
Item 4
Does anyone have an idea on how to fix that? Otherwise I always get
problems with my markup designer.
Regards
Malte

Re: Custom Component Converter not called
Am 07.09.2013 22:19, schrieb Sven Meier: if you don't specify the type, a TextField will try to resolve the type from its model, see AbstractTextComponent#resolveType() and IObjectClassAwareModel. Thanks for this hint. During further tests after my mail, I found a situtation where the convertToString is called, but not the convertToObject. The initial situation is the same as described in the first mail. Then the model is updated by an ajax-call from null to a value, the output call my ToString-Method, but a later form submit doesn't call the ToObject-Method. It seems the problem occurs in AbstractTextComponent.resolveType. This function tries only once to resolve the type. In the first call the function sets type to null. This is not my problem anymore. I can solve my special problem with the IObjectClassAwareModel. Malte >Shouldn't there be a pre-examination wheter a component converter is available? Without type there can't be a converter.

AjaxEventBehavior that catch only some keypresses
Hi!
I want write an AjaxEventBehavior that calls the server if an function
key is pressed. Im also need to know on serverside which key is
pressed.
I'd tried it with this code:
public HomePage(final PageParameters parameters) {
super(parameters);
add(new AjaxEventBehavior("keydown"){
@Override
protected void updateAjaxAttributes(AjaxRequestAttributes
attributes) {
super.updateAjaxAttributes(attributes);
IAjaxCallListener listener = new AjaxCallListener(){
@Override
public CharSequence getPrecondition(Component component) {
//this javascript code evaluates wether an
//ajaxcall is necessary.
//Here only by keyocdes for F9 and F10
return "var keycode =
Wicket.Event.keyCode(attrs.event);" +
"if ((keycode == 120) || (keycode == 121))" +
"return true;" +
"else" +
"return false;";
}
};
attributes.getAjaxCallListeners().add(listener);
//Append the pressed keycode to the ajaxrequest
attributes.getDynamicExtraParameters()
.add("var eventKeycode =
Wicket.Event.keyCode(attrs.event);" +
"return {keycode: eventKeycode};");
}
@Override
protected void onEvent(AjaxRequestTarget target) {
//Extract the keycode parameter from RequestCycle
final Request request = RequestCycle.get().getRequest();
final String jsKeycode = request.getRequestParameters()
.getParameterValue("keycode").toString("");
target.appendJavaScript("alert('from wicket ajax. you
pressed "+jsKeycode+"')");
}
});
My Problem is, that this blocking all Inputevents on all Inputfields
on the page. I find out, that the result false in the
Preconditionscript cause in a stopping of Eventhandling.
What can I do, that only the keys 120 and 121 result in an
ajaxcallback and leave all other keyevents untouched?
