Re: Bookmarkable ModalWindow

[Martin Terra]

Thanks. The question was formulated from the perspective of the old
Modal Window.

However, maybe they are equivalent, and if not, what are the caveats?

If any, what are the relevant differences between new and old in this
respect?

Bookmarkable ModalWindow

[Martin Terra]

Hi!

Has anyone made a bookmarkable use case of ModalWindow, are there any
caveats?

Basically the goal would be that refreshing the page retains its state as
if it was a regular panel.

IMO ListItemModel is more of a Lense than a model ;) Rename perhaps?

Re: ListItemModel is not detaching List-model

[Martin Terra]

Normally it's the other way, a component detaches it's model.

The ListItemModel isn't really holding any data, it is relying on the
actual model held by listView.

Part-Time Remote Java Wicket Job Opportunity

[Martin Terra]

Hi!

We are looking for someone well versed in Java Wicket to implement a
sliced html template as live Wicket pages, according to our coding
conventions and requirements. There might be multiple similar such tasks
along the way (longer term).

We will be paying you via invoice, so you need to be incorporated.

If you are available, please contact me directly. Tell us about your past
experience with implementing sliced html in Wicket. We would also like to
see some work (what your code looks like) that you have done using Wicket.


Yours sincerely,
Martin Terra

Re: Wicket on low end hardware

[Martin Terra]

MartinG mentioned ComponentRenderer so if you know your pages, you could do
that.

If you need help with ComponentRenderer, please first proceed with it and
maybe a more specific question might help once you have gotten started.

Re: Wicket on low end hardware

[Martin Terra]

Just a note, you don't need to make the startup "pre-touching" process a
blocking one so that if a user were to interact with the app, they could do
so while startup pretouch is doing its thing.

And you could profile whether you want to do the pre-touch in single thread
or multi-thraded.

Re: Wicket on low end hardware

[Martin Terra]

Anything in wicket can be preloaded,  but as premature optimization is
evil, you should profile your application.

If you do not have debug access to a real/simulated environment then the
least you can do is make your own thread logger to log what the threads are
doing.

It might be interesting from wicket perspecive. Anyways, I will kick its
tires and maybe make a quickstart or a reference implementation.

I appreciate these tips.

Re: Wicket MVVM

[Martin Terra]

Thanks, interesting. First impression it's quite some
annotation-heavy-soup. Was hoping for more wicket-like 100% pojo/lambda
approach and more clear divide&conquer separation of
view<->viewmodel<->persistence in a way that I can implement or plug
something else for persistence.

Anyways, will have a look if it can be used efficiently.

Wicket MVVM

[Martin Terra]

Hi!

Is there a library/example/experience for doing MVVM with wicket (or
something close enough to serve as a useful reference)?

A practical goal would be to decouple the Wicket stack from other layers
and automate gui code generation based on predefined patterns & layout
design (benefits would be stabilty, testability, predictability, standard
practices, maintainability, upgradeability, code generation/ai code
copilot, etc.).

Preferably it would work even so far that we could plug/attach either
jakarta poi or wicket to the same model and get as output (for example)
either a html table or excel sheet.

How it works is, basically you would have a wicket plugin that
"interprets/implements" the model. Alternatively you could have a jakarta
poi plugin as well.

You could also have a mix of the two, for example: an instruction in the
model for an action (link, button, etc. rendered by the wicket plugin) has
an "embedded instruction" to further render an excel sheet via (a different
plugin) jakarta poi as a result of the wicket action (so that when the user
clicks the link, the user can download the sheet generated by the model via
a wicket download stream associated with the defined link/action).

Re: Blind XPath Injection Solution

[Martin Terra]

TL;DR In general wicket app should do server side validation and if client
submits a valid query then it might not be a problem, or you need to add
validation.

Does this ring a bell?

Re: Reg: Integrate Spring REST and OAuth2 in Wicket web Application

[Martin Terra]

Hi!

It should be quite straightforward once you start according to standard
practices and best principles.

You can find lots of resources via google, e.g.,
https://support.wicket.io/hc/en-us/articles/4411663172631-Getting-Started-with-SSO-OAuth2-SAML2-

Or have you already tried it and do you have a more specific question?

You might want to debug this functionality, then, maybe there is a bug or
maybe something is not happening which is not apparent on your screen.

Without seeing the code I cannot guess more.

Probably yes, AjaxSubmitLink aj AjaxButton are interchangeable, remember to
setDefaultFormSubmitBehavior(false) to avoid actually submitting and
processing the form.

What is your mechanism of showing the validation messages, is it automatic?

When refreshing component via ajax or other submit, you must use
button.setDefaultFormProcessing(false) to avoid validation.

If you refresh view without button, for example using a Link, a Link does
not submit the input data to the server and thus values are "lost" because
they are never received by the server.

When working with forms, all actions must use a form submitting behavior
(see AjaxFormSubmitBehavior) in one way or another (ajax or otherwise) to
send the values to server (in order for server to be able to repaint them
in response).

Re: Form components in ListView cleared if ListView is refreshed

[Martin Terra]

You can setReuseItems, but the number of your list items changes you will
need to implement some sort of FormComponentReuseManager

Re: Re: Automatically insert generated html IDs in other places in html file

[Martin Terra]

Can you provide more code to clarify your use case? A quickstart would be
helpful.

Without deeper insight into your project, I would simply implement a
reusable panel like this:

 
 
 Lorem ipsum dolor sit amet
 Content ...
 
  

In java you could then use this as an one-line element along the lines of:

new ReusablePanel("panel-id", "header-id");

You can extend and create your own flavor of WebMarkupContainer which does
all that you need or even a panel if the html is repetitive as well.

Re: Is there any way to get an error message when uploading a file that exceeds the size limit?

[Martin Terra]

Hi!

I would assume that you should set the form levele restriction stricter
than application or server level to allow the form to be processed and thus
give way for the onFileUploadException to be invoked.

Re: prevent client request being intercepted for attack

If you browse with a ZAP associated browser then I assume the https
connection is with ZAP.

You should only be concerned if you browse with a different browser than
one associated ZAP and then same occurs.

If you google wicket xsd it leads to https://wicket.apache.org/dtds.data/

If your "coders" provide all handles, the QA person can probably invoke the
hooks. Anways, your success odds are better if your QA is somewhat code
savvy, for example comfortable with running and debugging from IDE etc.

You might also want to divide and conquer, the QA person manages strategy,
scope and stats of tests and their results, and (delegates)  coders
maintain the actual tests.

We use WicketTester tests for regression tests and selenium tests for
availability tests.

Here's a hassle free guide to set up type safe testing without using string
property paths:

https://cwiki.apache.org/confluence/display/WICKET/Type-safe+testing+in+wicket

I'd say the overhead of selenium doesn't pay off using it for all tests,
but your mileage might vary.

Re: add Dropdown object to List

[Martin Terra]

I'd recommend: Keep it simple, implement using dropdownchoice and simply
convert to a list in your selection model if you need a list for domain
model purposes (I cannot comprehend why you would use a list to represent a
single selection).

Re: add Dropdown object to List

[Martin Terra]

Selection is an object. If you want to transform it to a singleton later it
is a separate process. Or you need to build a model that does that, but for
PoC purposes I suggest you keep it simple and do by the book without list
at receiver.

Re: add Dropdown object to List

Choices model should be final and the selection model should be one item
not a list

Re: tag into tag

[Martin Terra]

Hi!

To me it looks like you have a webmarkupcontainer and a small label inside
it. Or how do you expect it to render?

If all text is dynamic then I would still make it one label which partly
generates html markup.

Hi!

Can you paste some code with your exact (generic) variables which doesn't
work, it might be easier to figure out from code example than verbal

In my experience a good trick is to search from wicket source with any
keywords you find from the logs, and work from there, add more debug
logging where necessary.

Re: Page is being lost from Session intermittently

[Martin Terra]

Hi!

Have you logged everything from the servlet container's session manager to
wicket session management, to identify the logic where loss occurs?

If necessary, you could compile a custom version of these from sources, to
add more necessary logging, to trace where the ball drops.

For example, did you try with different servlet containers if same
problem occurs? Jetty, Tomcat, something else? Just to rule out the servlet
container.

Job opening, Wicket developer, full time remote position

[Martin Terra]

Hi!

We are looking for a talented Wicket & UI developer for a full time remote
position.

You would be working with us on an online work time tracking saas product.

Heavy focus on real world usability and canonical implementation logic.

It is an inhouse developed product, not a consulting gig.

If you are available, please contact me directly.


Yours sincerely,
Martin Terra

Re: Why aren't setEnabled and setVisible model based?

[Martin Terra]

You often need to know overall UI state to determine visibility, and you
would end up with anonymous model classes of some sorts, so my educated
guess is there is not much expected benefit, only caveats. One would expect
a model to work and end up doing twice the work eventually using an
anonymous class or overriding onConfigure.

Re: Issues with refreshing panel with form

[Martin Terra]

Did you debug clearinput and model detach whether they occur expectedly?
Snipplet is too small to see the big picture, and at the same time it seems
too complex to get the big picture quickly from code (maybe you could share
a 15 line pseudocode spec for the form, what it's intended to do)?

Re: Preventing the ModalWindow from being rendered as iframe

Hi!

Javadoc says ... *If the content is a page (iframe)* ..

Can you show your code, if you are using a panel or a page as its content?

Maybe something along the lines of a stateless page&upload form without a

Re: setHeaderResponseDecorator cause problem logging into my app

[Martin Terra]

Then you could try to debug it using browser developer tools (inspect
element, debugger etc.).

Usually there is an issue like conflicting js or missing dependencies
(throws exception on js), or something along those lines. Also could be
that dependencies are injected in wrong order, or you might accidentally
override some default js you are normally providing.

I would maybe start by taking a diff between a browser page
(source) without the change and a browser page (source) with the change,
maybe it will point you to some direction.

You're welcome. To clarify: validation can prevent any malicious effects of
injected values, but it cannot prevent the injection itself. Therefore,
validation could cure the issue found in the report. This should
ofcourse be verified by reproducing the issue before fix and confirming
that applying the fix successfully mitigates the issue.

Re: About XML Injection

[Martin Terra]

So long as you are able to reproduce the issue and evaluate if you can
confirm the fix, it should be ok. You can then finetune the solution.

Re: About XML Injection

[Martin Terra]

Can you solve this by simple validation if submitted values are legal? This
way it does not matter if client tries to override the submit.

Re: About XML Injection

[Martin Terra]

I'd recommend you simply include it with maven options into your IDE this
way it is always there with you.

You can googe it, and there are some recent previous wicket threads about
it too:

[Martin Terra]

You could override some of the methods that do the injecting. Do you have
the wicket sources?

Re: Where to download Javadoc for Wicket 8.x?

[Martin Terra]

I would recommend to plug in the libraries with maven together with the
source option, this way you have both the wicket source code and the
javadoc.

Re: Retrieve user's page on the site

[Martin Terra]

In our experience these can be a mixed bag of expired requests, expired
links, incorrect back button presses (and links from stale pages), session
timeouts, etc.

We haven't been able to trace them either, if a solution exists, I wish it
was part of wicket core.

Using more human readable urls might help, identifying session and clicked
button and maybe page state, which could be later backtraced to determine
any inconsistencies.

Re: Application not seri

[Martin Terra]

Follow the stacktrace, looks like there is a reference to
ava.lang.Object org.apache.wicket.Component.data
[class=[Ljava.lang.Object;]

maybe anonymous class? If you need an Object, you need to make a
SerializableObject extends Object implements Serializabe ...

Just study the stacktrace, it will become clear.

Re: Question about IChoiceRenderer

[Martin Terra]

I would definitely recommend leveraging the class hierarcy
of DropDownChoice/AbstractSingleSelectChoice in case you are using a single
select, and if it is multi select then respective ListMultipleChoice.

This way you can leverage the existing implementation of isSelected etc.
