How can I "catch" query parameters and pass it to the form?

[ivan.tufegdzic]

Hi,
I have a query and when I run it.s. Base on these values, the query will return all records meeting the conditions. Now, I want to "catch" these values and use them as criteria to
manipulate data from the query and show corresponding records on the form.

I must not use annotation RequestParameter.
I must use namepage.page.xml.

Can you show me how to do it?

Thank you,
it

Here's one source of documentation for it.

Simply bind parameters in pages.xml to values in the backing component to get a 2 way passing of values from the form to the backing bean via request parameters.

i.e.

<page view-id="mySearch">
<param name="lastName" value="#{myBean.lastName}">
</page>

Now, when you call \mySearch.seam?lastName=smith the value will be put into the backing bean.

On your form, you simply put :

 <h:inputText value="#{myBean.lastName}"/>

and the parameter will appear in the form based on the parameter.

So the parameter makes the trip from parameter in the request-> Put into the backing bean -> Value on the form bound to the backing bean.

When you run the query, you can just refer to the lastName field in the MyBean class to get the value.

Yes, I understand.
That works.
I have dynamic list as parameters, and I don't have name (it will be unknown).
I wrote a servlet which catch parameters with names and its values.
That is good because in query I may put unknown names and its values.

Is that ok?

Thanks
