Browser/Client info navigatorJavaEnabled property returns undefined

2016-05-25 Thread ravala

Hi, 

I was trying to use WebClientInfo to get browser information on the server,
In the Ipad chrome
when retrieving  'navigatorJavaEnabled' is returning 'undefined' instead of
true/false.

The problem is as  'undefined' is string but server is expecting boolean,
leads to exception and causing  browser to reload continuously.

possible solution 

In wicket-browser-info.js
--
info.navigatorJavaEnabled = window.navigator.javaEnabled() || false; 


Regards,
Ramesh V

excuse me by all this handycopying i lost the part you mentioned if you would 
have looked at the example i send you you would have seen that the instruction 
is :

tester.executeBehavior ((AbstractAjaxBehavior) 
tester.getComponentFromLastRenderedPage("form:land").getBehaviors().get(0));

This is just an execution of a getter.
You need to tester.executeBehavior(ajaxBehavior) it

Re: Generate css from less for package resources at runtime.

2016-05-25 Thread Lars Törner

Hi Martin, Bas and others!

Unfortunately I got one crucial thing wrong when I described our scenario.

"A less-variable (put in a separate file) gets a new value."

This is not the case, the variable is changed in code and not in a file.
This means that even though we have changed a less variable and regenerated
the css, the less files themselves has not changed (no new modification
time), and therefore the problem we have arises.

To touch the css-file might be a work around, but it seems kind of a
strange way to handle things.

Cheers
Lasse

2016-05-25 Thread Bas Gooren

Lars, Martin,


Sorry for hijacking this thread (sort of).


Hmmm, I am 100% sure it was not working for us in a web app we currently
have running.

I just checked which version of wicket-bootstrap-less it uses (version
0.9.11), and that version already has the recursive check on the
last-modified time of imported sources.


I’ll try to do some debugging to see if it really is not working, and if
that’s the case: why it’s not working.

Met vriendelijke groet,
Kind regards,

Bas Gooren

the selection of this field sets the Choices of another DropDownChoice  by

Here you use Ajax behavior to submit the form component. protected void

});
if i select land but don't select orte
and then click at the nextButton

when i simulate this behaviour by WicketTester and FormTester 

formTester.select("land", 0);
Here you don't trigger trigger the Ajax behavior to update the model object of 
this form component, so its value is still the old. 
.getComponentFromLastRenderedPagtestere("form:land").getBehaviors().get(0));tester.assertVisible("form:orte");
