Url Parameter in Custom Component

[Manuel45 (Manuel Di Stefano)]

Hello,

i have a couple of custom class in my application. A custom class extend VerticalLayout and implement View. I call it by http://myapp/#!/customclass.

Now i want get a parameter like httt://myapp/ #!/customclass/?test=hello. I tried implementing Handler Request interface but it didnt work.

In general i cant understand how get a parameter outside my init(VaadinRequest requet) method. Can someone help me plz?

httt://myapp/ #!/customclass/?test=hello.

There’s your problem; the an HTTP URI, the request parameters come
before
the URI Fragment. From
Wikipedia article
(easier to understand than the RFC, and the first result on my quick google!)

@Wikipedia

Every URI is defined as consisting of four parts, as follows:
: [ ? ]
[ # ]

In other words, your URL should be http://myapp?test=hello#!/customclass

In general i cant understand how get a parameter outside my init(VaadinRequest requet) method.

You simply need access to the VaadinRequest object - which you can get via the
VaadinService#getCurrentRequest()
method, e.g.

String value = VaadinService.getCurrentRequest().getParameter("test") HTH,

Cheers,
Charles.
