But not just marketing team of that company, the industry trend is more towards those JS frameworks like Angular, React etc.. So wanted to know where do Wicket stand against those.. We wil be in a better position to answer questions down the line.. As an Architect when you make decisions, you need to stand by those and prove it.. This topic was intended to clarify & get more insights to be able to make decision. - fzb -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Wicket-vs-JS-frameworks-tp4675771p4675798.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

First you need to answer yourself what kind of application you need. What is its target audience. What developers you have. Wicket is just a tool in the box. If you want to be developer above the average then experiment with new technologies. Only this way you will have an opinion. I can tell you anything good or bad about any technology (they all have their shortcomings) but this should not be a reason to use it or drop it from the options. I personally try to use only technologies that *I* like, not because the marketing team of some company said that their product is the best.

Re: DropDownChoice with ChoiceRenderer
:) yes, that was it:
@Override

DropDownChoice with ChoiceRenderer
Hello,
I'm using Wicket 7.
I have this simple use case where I need to have a dropdownchoice, where to
display some values, but the model should retain other values.
I have done the following, however, the model always retains null.
So my dropdownchoice should display Code1 and Code2 but save in the model
the values C1 or C2. Instead it always saves null.

public TestForm(String id, IModel model) {

Bookmarkable link doesn't become a https link
Hi, we had a problem where a bookmarkable link didn't become a https link. I found this: https://cwiki.apache.org/confluence/display/WICKET/How+to+switch+to+SSL+mode Which, with a warning, states: "It is extemtely important that when setting the rootRequestMapper it is done AFTER you have added any bookmarkable links otherwise they will not be switched over to Secure mode." I found that we in our Application.init() did the opposite, i.e. set the rootRequestMapper before the page mounting. Problem solved, I thought. Instead the problem was that the page wasn't mounted at all, and the only thing that worked was to mount the page and keep the order we had, which, according to the link and the warning above is bound to fail. Please, can anyone tell me what I'm missing here? Wicket version: 6.22. Cheers Lars
Re: Wicket vs JS frameworks.
The "new" JS Frameworks in combination with JSON have made quite cheap building CRUD web app. But there are a number of factors that I personally don't like at all with this type of solutions: - they only work with single-page applications. period. SPA is not a silver-bullet, it's not the best solution for everything. - the same can be stated for JSON. I might need to use another data format and maybe I might prefer a relational db instead of Mongo... - hard to test your app in isolation. With wicket you can test your generated HTML without even using a server. - standard "bending": you have to use something that is not pure HTML (custom tags, JSX, ...) and then COMPILE it to something standard (most of the time JS) :-( - ... My 3 cents. On 14/10/2016 06:33, fzb wrote: Hi, I am a fan of Wicket & had been working on for last 6 to 7 yrs using the same.

Yes, we can embed some components from React or Angular if this works. But again maintaining compatibility over release cycles is an issue.. If there was some built in mechanism in wicket, it would be ideal. Is any one attending this conf ?

Re: Repeat every 2 rows in a table
Hello Per, thank you for the links.
I have following html code:
Name
Code
Id
The Java code looks like this:
public TestPage(IModel model) {
super(model);
TestForm tst = new TestForm("testForm", model);
tst.setOutputMarkupId(true);
add(tst);
}
class TestForm extends Form {
/**
*
*/
private static final long serialVersionUID = 1L;
public TestForm(String id, IModel model) {
super(id, model);
List beans = Arrays.asList(new TestBean("Name1", "Code1", 1),
new TestBean("Name2", "Code2", 2));
add(new ListView("forEachItem", beans) {
/**
*
*/
private static final long serialVersionUID = 1L;
@Override
protected void populateItem(ListItem item) {
item.add(new Label("itemName", new PropertyModel(item.getModel(),
"name")));
item.add(new Label("itemCode", new PropertyModel(item.getModel(),
"code")));
item.add(new Label("itemId", new PropertyModel(item.getModel(), "id")));
}
});
}
@Override
protected void onSubmit() {
logger.info("OnSubmit");
}
}
The code crashes here because itemId belongs to another row.
Could you please advise?
Thank you

REST should not be a criteria for going with JS based systems. We do have mobile apps, we expose REST services using Spring. We dont need the same data in web & mobile most of the time. For mobile it is very much limited. So having a separate REST layer works well. Lets wait n hear from some more experts on this topic.

Re: Clear input form values
We can only advise on the code that you give us.
Your real code may not work for many other reasons but since you give us
some incomplete copies of it we have no idea what is wrong.

Re: Clear input form values
Hello,
The txtName field has the .setOutputMarkupId(true).
I have also added it to the form.
But it doesn't work howevere.
I have event tested adding it to the txtLink, but still no change.
However, the issue appears to come from the
txtName.add(new AjaxFormComponentUpdatingBehavior("change") {...}
If I comment out this part, the clear is done.
But I need to have this behaviour kept.
Could you please advise?
Thank you

Re: Repeat every 2 rows in a table
Hello ganea, you can find many information about your problem at http://examples7x.wicket.apache.org/index.html espacially http://examples7x.wicket.apache.org/repeater The user guide can you find here https://ci.apache.org/projects/wicket/guide/7.x/ Repeaters are explained here https://ci.apache.org/projects/wicket/guide/7.x/guide/repeaters.html You can add a markup container to a list view item and add the required row components to it.

Don't keep references to other pages.
Use PageReference instead.

1. There is no need to add 'txtName' to the target because its parent
(TestForm) is added
2. Neither of them have .setOutputMarkupId(true), so Wicket won't be able
to update them in the DOM. It should even complain about this.

Clear input form values
Hello,
I'm using Wicket 7.
Please help me with the following.
I have a test form, with only one input text field on it.
When pressing on a link, I need to have the values in the form cleared out.
This is the html and java code, but I could not make it work, the input
field just won't clear.
Name:
public TestPage(IModel model, final ReturnObjectPage returnPage) {
super(model);
this.returnPage = returnPage;
add(new TestForm("testForm", model));
}
class TestForm extends Form {
/**
*
*/
private static final long serialVersionUID = 1L;
public TestForm(String id, IModel model) {
super(id, model);
TextField txtName = new TextField("txtName", new
PropertyModel(getModelObject(), "name"));
add(txtName);
txtName.add(new AjaxFormComponentUpdatingBehavior("change") {
private static final long serialVersionUID = 1654345477970524731L;
@Override
protected void onUpdate(AjaxRequestTarget target) {
target.add(txtName);
}
});
txtName.setOutputMarkupId(true);
AjaxLink clearLink = new AjaxLink("clearLink", model)
{
/**
*
*/
private static final long serialVersionUID = 1L;
@Override
public void onClick(AjaxRequestTarget target) {
model.setObject(new TestBean());
TestForm.this.clearInput();
target.add(TestForm.this);
target.add(txtName);
}
};
add(clearLink);
}
@Override
protected void onSubmit() {
logger.info("OnSubmit");
}
}
