Request Parameter
Hi, I have this page, it contains a product that has a list of options.
The product has a name that can be changed, and you can change the options.
My Problem is when submitting the table form save button, I do not have the
product id anymore.
So in the OnInit method I can not get the data.

Any chance you can provide with a code example that takes base on what I

When you view the page on the first place, you are using the get method and
consequently the public page parameter. After that, on submit, you are
using the post method and consequently the hidden field defined on your
form.
You set the hidden field of your form with the public parameter on the get
method and get it back (the hidden field) on the submit action.

How can this help me.. ?
The first method called when the save button is pressed if the OnInit()
method.. and the productId is null.
Don't quit understand how I can use the post method...

Re: Request Parameter

I have one form, and actually 3 FormTables.
I have a submit button for each of the 4 forms.
When submitting one of the table forms, I managed to stay on the same page
and keep the productId, so the redirected the product is loaded again.
But I has to add a HiddenField to every form.
I had a cancel button for each of the FormTables, but I could not get that
to work. The idea was to have the cancel button not submit anything, but
only refresh the page with data from the server.
Here is a part of the code that relates to the quantityFormTable
protected HiddenField idField3 = new HiddenField("id3", Long.class);
private FormTable quantityFormTable = new FormTable("quantityFormTable");
quantityFormTable.getForm().add(idField3);
private void init(final Long productId) throws SystemException {
...
idField3.setValueObject(productId);
...
}
button = new Submit("save", "Save", this, "onSaveQuantityFormTable");
button.addStyleClass("btn btn-primary");
quantityFormTable.getForm().add(button);
public boolean onSaveQuantityFormTable() throws SystemException {
if (quantityFormTable.getForm().isValid()) {
List<ProductQuantityEnt> productQuantities = quantityFormTable.getRowList();
dashboardSBBeanLocal.saveProductQuantities(productQuantities);
}
Long id = Long.parseLong(idField3.getValue());
HashMap<String, String> m = new HashMap<String, String>();
m.put("productId", "" + id);
setRedirect(EditProduct.class, m);
return true;
}

Re: Request Parameter
Posted by Bob Schellink <sa...@gmail.com>.
I never used FormTable but from the screenshot it seems you have a Form and a FormTable on the page.
Are you submitting the Form and expecting the FormTable to be submitted as well? That won't work
since HTML only sends the form data you are submitting, not all forms on the page.
regards
Bob

Re: Request Parameter
Posted by Kristian Lind <kl...@gmail.com>.
When I press the save button on options, OnInit() is the first method to be
called, but the productId is null.
*How can I make sure it gets the productId ??? *
The next method that is called is the
public boolean onSaveOptionFormTable() throws SystemException {
if (optionFormTable.getForm().isValid()) {
List<ProductOptionEnt> productOptions = optionFormTable.getRowList();
dashboardSBBeanLocal.saveProductOptions(productOptions);
}
Long id = Long.parseLong(idField1.getValue());
HashMap<String, String> m = new HashMap<String, String>();
m.put("productId", "" + id);
setRedirect(EditProduct.class, m);
return true;
}
but here the productOptions list is empty... cause of the null productId
from the OnInit() method.
The next method is then again the OnInit() method, and now there is a
productId.. cause the
m.put("productId", "" + id);
in onSaveOptionFormTable.

Re: Request Parameter
Posted by Kristian Lind <kl...@gmail.com>.
I have been looking at those examples. I cant find any that have the needs
I have.
I am displaying one product, so the page need the id of the product. Which
it get from the previous page...
But I wanna stay on the page after saving... the examples return to another
page.
I am trying to do some like this..
http://click.avoka.com/click-examples/source-viewer.htm?filename=WEB-INF/classes/org/apache/click/examples/page/table/FormTablePage.java
Here all the customers are fetched...
*public* DataProvider createDataProvider() {
DataProvider dp = *new* DataProvider() {
*public* List<Customer> getData() {
*return* customerService.getCustomersSortedByName(NUM_ROWS);
}
};
*return* dp;
}
Whereas I need to get the options from a specific product.
I now managed to be able to stay on the page, so the productId is used in
the save methods..
Long id = Long.parseLong(idField1.getValue());
HashMap<String, String> m = new HashMap<String, String>();
m.put("productId", "" + id);
setRedirect(EditProduct.class, m);
The problem now is that in the in the method onSaveOptionFormTable()
the
List<ProductOptionEnt> productOptions = optionFormTable.getRowList();
is empty.
So no options are updated...
and the onInit() method has no productId.

Re: Request Parameter

Kristian, I would like to suggest another alternative until you get used to
the click framework. The view->edit[1] and view->insert pattern is a good
point to start and after you have more expirience with the framework you
can do more experiments.
That was what I did [2] and after that I could understand how the framework
is simple.

Re: Request Parameter

The problem is I have no where to get the Id from in the onSave method..
the idField is empty and is not set the in the OnGet() method cause the
request parameter is null.
I wanna do
HashMap<String, String> m = new HashMap<String, String>();
m.put("productId", idField.getValue());
setRedirect(EditProduct.class, m);
if I test with a hardcoded id
HashMap<String, String> m = new HashMap<String, String>();
m.put("productId", "1");
setRedirect(EditProduct.class, m);
it works... so I don't think I have to use the alternative redirect
methods.

Re: Request Parameter
Posted by Kristian Lind <kl...@gmail.com>.
Hi, I have been looking at the links, and I did some changes to my code.
But I can not get it to work.
When I press the save button the OnGet() method is called with no ID, and
after that the onSave() method is called, but now the idField is empty...
I want to stay on the same page after save is pressed... also when the save
buttons for the form tables are pressed.

Re: Request Parameter
Posted by Gilberto <gi...@gmail.com>.
I think you misunderstood the page flow[1] and onInit method usage[2]. Take
a look at this example [3], there you will see some work division.
It shows some click + cayenne/jpa integration code, just my learning
repository.
Regards,
Gilberto
