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).

Why not simply write the code as is? Guy. From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Tuesday, July 15, 2008 10:30 AM To: users@myfaces.apache.org Subject: 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? This message is for the designated recipient only and may contain privileged, proprietary, or otherwise private information.
