Re: Java Wickets Refresh Model Window

[Sven Meier]

You should clear the textField's model and update it:

  textField = new TextField(...);
  textField.setOutputMarkupId();

  onSubmit(AjaxRequestTarget target) {
...
textField.setModelObject(null);
ajaxRequestTarget.update(textField);
  }

Hope this helps
Sven

Re: Bean not properly injected into another bean when using Wicket stateless page

[Tomasz Dziurko]

Hi Martin

Two questions:
1. Which class? HomePageHandler ?
2. I have digged deeper and in fact there is a check whether to use CGLib
or Objenesis (if there is no-args constructor Objenesis is chosen) but is
it an expected behaviour? Or maybe this case could be a trigger to discuss
proper way to deal with such cases?

I think you will need an additional default constructor for this class.
CGLIB needs it.
It might have lesser visibility than public too.

CommandPublisher commandPublisher) {
this.commandPublisher = commandPublisher;

Java Wickets Refresh Model Window

[ASHU_JAVA]

Hello All,

I'm having a table containing a button on each row.
Onclick of this button, a model window appear, providing user two options,
either use text field for single record or upload a file for multiple
records and then click "Add Details" button to save the record(s) in
database.

The issue is if a user enter data in text field OR upload file then the user
input's reference remains existent even after the clicking of "Add Details"
button.
Thus, the data remains present and if the user clicks on "Add details"
button again, it executes the last performed operation again "single record
entry using text field input" OR "multiple record entry using File upload".

What I want to achieve is to refresh the model window after clicking the
"Add details" button, remove the reference of last executed operation and
make sure that the user enter the text field or upload the file again to
repeat the ADD DETAILS operation.
Currently I've to close the model window and refresh the Parent page to
reload everything.

The Page view looks like the below attached image.

 

Can anyone please share some input to achieve this functionality?

thanks in advance.

Re: Jquery Plugins

[Sebastien]

Hi,

If you would like to integrate a jquery plugin in wicket, wicket-jquery-ui
can probably help you.
You have an example here:
https://github.com/sebfz1/wicket-jquery-ui/tree/master/wicket-jquery-ui-plugins/src/main/java/com/googlecode/wicket/jquery/ui/plugins/datepicker

Jquery Plugins

[SeldonCrisis]

Hey everyone, is it possible to incorporate a Jquery plugin in my Wicket
page? Specifically, I would like to use this: 
http://innostudio.de/fileuploader/   

It is a file upload plugin, but I am adamant on using it because it allows
users to upload multiple documents and give their uploaded documents a
specified metadata title. Do I need to do this in its own panel, or maybe
create a modal? I would be grateful for any hints in the right direction.

Thanks a lot guys

Re: Wicket back button behavior

[Martin Grigorov]

Hi,

The Wicket way would be to roll your own IPageManager or IPageStore or
IDiskStore and implement #getPage(int pageId) in a such way so that it
always returns the last used page by the user (i.e. session).
You may use https://github.com/martin-g/single-page-instance as an
inspiration.

Otherwise you may also try to do it at the client side, i.e. with
JavaScript.
Play with History APIs - pushState(), replaceState(), history.forward(),
history.go(history.length-1), etc.

Great!

I've added few convinience constructors to RenderPageRequestHandler in
