How to create commandlink programmatically
We have a system built on seam/richfaces. There's this webpage where the tables are rendered from dynamic context (from multiple different datasources, and each of them uses a different layout to represent essentially the same real world concept). As a result, this table is binded to a bean, and it's columns/layout are generated from this bean.
Now I need to add a command link on a specific column, equivalent to
<a4j:commandLink value="#{actBean.Ids}" action="#{actBean.genDetails}">
<f:setPropertyActionListener target="#{actBean.Ref}" value="#{cont}"/&g开发者_StackOverflow社区t;
</a4j:commandLink>
in a JSF page.
The table is binded to a managed bean with
HtmlDataTable dataTable = new HtmlDataTable();
HtmlColumn column = new Column();
//some code to setup column name, value etcs
dataTable.getChildren().add(column);
//What do I do here to bind a commandlink with a property action
//listener to column?
My question is, how do I do this programmatically?
Thanks!
HtmlAjaxCommandLink commandLink = new HtmlAjaxCommandLink();
commandLink.addActionListener(new SetPropertyActionListener(target, value));
column.getChildren().add(commandLink);
where target
and value
are ValueExpression
's. These can be created with:
ExpressionFactory.getInstance().createValueExpression(ctx, expression, expectedType)
And the required ELContext
can be obained via FacesContext.getCurrentContext().getELContext()
