Re: [Trinidad] creating tr:table using binding

Exactly, it should display "xxx", but it doesn't.

But his expression is ok as well - #{'xxx'} should work, it should
display xxx...

Hi,
I'm trying to create a tr:table using binging, and almost everything
works fine except, getting row values in table.

I've created in index.xhtml this:

<tr:table binding="bean.table" />

and in backing bean crating columns, and outputText inside columns. This
is working well, but I can't figure out how to set value to the
outputText as an expression using row value. Example:

table.setValue(getMyData());
table.setVar("row");
CoreColumn column = new CoreColumn();
column.setParetn(table);

Don't do this!  setParent() is called for you.  Don't ever call
it on your own (see the Javadoc).

column.setTransient(true);
CoreOutputText text = new CoreOutputText();
text.setParent(column);
text.setTransient(true);
column.getChildren().add(text);
table.getChildren().add(column);

and now the tricky part. How to set an value to text?

1. case
text.setValue("bla");  --- it works, "bla" is showing in each row of the
table.
2. case and 3. case
ExpressionFactory ef =
FacesContext.getCurrentInstance().getApplication().getExpressionFactory();
ELContext elContext = FacesContext.getCurrentInstance().getELContext();
ValueExpression value =
ef.createValueExpression(elContext,"#{'xxx'}",String.class);

text.setValue(value) --- "ValueExpression[#{'xxx'}] is showing as output
in table cell
text.setValueExpression("value",value) --- table cell is empty

You want text.setValueExpression() - the problem will be that
your ValueExpression is wrong.  It needs to be something like:

ValueExpression value =
ef.createValueExpression(elContext,"#{row.xxx}",String.class);
