Creating child automatically
Hi,
i need a custom column that render automatically a check box child. So,
what I need is insert, automatically, in the table the tags:
<t:column >
<t:selectBooleanCheckbox value="#{xxx}"/>
</t:column>
inserting just the tag <xx:mycol>.
To do that, I have developed a my custom tag and a my component. The
component extends org.apache.myfaces.custom.column.HtmlSimpleColumn and
override the encodeBegin in this way:
public void encodeBegin(FacesContext context) throws
IOException {
super.encodeBegin(context);
Application app = context.getApplication();
if (this.getChildren()== null ||
this.getChildren().size() == 0){
UIComponent parent =
this.getParent();
if(parent instanceof HtmlDataTable){
HtmlSelectBooleanCheckbox select =
(HtmlSelectBooleanCheckbox)app.createComponent(HtmlSelectBooleanCheckbox
.COMPONENT_TYPE);
select.setValueBinding("value",app.createValueBinding("myvalue"));
this.getChildren().add(select);
}else {
log.warn("Parent
component must be a data table of class "+HtmlDataTable.class);
}
}
}
What I do, I simply add a child with the HtmlSelectBooleanCheckbox just
if I don't have any childs.
Is this the correct way to that?

Because there are a high number of developers and I want hide the way to
set the value of this kind of checkbox (I use the custom component in
table with a checkbox in each row for the multi selection).

Hi,
Why do you need a specific component for this task? Why not simply write
the code as is?
