Hi,
I have to develop a new JSF component (component, tag and renderer).
The goal of this new component is easy... Put together severals input zone in
one single component.
I have done somethink that works... But i'm not sure I did everything
correctly. (in the State of Art)
--> Should be great if I can get a link to a complete tutorial or full sample.
I create some code I don't like:
--> I have to "hardcoded" in the backingbean the "id" of my component and then
cast it to my component.
In my backingbean, the code looks like this:
UIComponent temp =
FacesContext.getCurrentInstance().getViewRoot().findComponent("dialog:dialog-body:mltext");
UIMltext myComponent = (UIMltext) temp;
During reading documentation I have found it is possible to "add" component in
the JSF tree dynamicly with code like this:
public void addControls(ActionEvent actionEvent)
{
Application application = FacesContext.getCurrentInstance().getApplication();
//Question: how to get controlPanel ???
List children = controlPanel.getChildren();
children.clear();
for (int count = 0; count < numControls; count++)
{
HtmlOutputText output =
(HtmlOutputText)application.createComponent(HtmlOutputText.COMPONENT_TYPE);
output.setValue(" " + count + " ");
output.setStyle("color: blue");
children.add(output);
}
}
Is it necessary in my component. What is the goal of adding component in the
tree?
I can now do: "MyValue myValues = myComponent.getValue()"
Then I have to do somethink like:
backingBean.setValue1(myValues.getValue1());
backingBean.setValue2(myValues.getValue2());
...
backingBean.setValuex(myValues.getValuex());
Is it correct? I should prefer the setter are called by JSF layer. Is it
possible?
Thanks a lot.
Stéphane
