What is wrong with this code
Hi,
I have a problem about creating dynamic HtmlDataTable component. The
following code renders only the column's facets. NOT the CONTENTS...
Thanks...
HtmlDataTable dataTable = new HtmlDataTable();
for (int i = 1; i <= 10 i++)
{
UIColumn column = new UIColumn();
HtmlOutputText header = new HtmlOutputText();
header.setValue("Column Header"+i);
column.setHeader(header);
for (int j = 1; j <= 100 j++)
{
HtmlOutputText rowText = new HtmlOutputText();
rowText.setValue("Row:"+j+"Column:"+i);
column.getChildren().add(rowText);
}
dataTable.getChildren().add(column);
}
return dataTable;

No Enrique, it's not the point. I am creating a vector of these
components and I am using FacesContext over vector. I think the
problem is about HtmlDataTable component, any ideas please...

Try not to create the components through the "new" mechanism, but using
FacesContext.getApplication.createComponent...

To me not, but i am not sure what you want do achieve.
creating a column,
creating a outputText as header and add it to the column.
and now create 100 outputText and add them as child to the column ?
This did not create a 100 row table!

Yes Volker,
It's exacly the way I wanna do. I want to display 100 rows, 10 columns
table with header on each column.
Supposed to see the following result.
------------------------------------------------------------------------
Column Header 1 # Column Header 2 ... 10 columns here
-----------------------------------------------------------------------------------
Column Row 1 # Column Row 1
100 rows here
-------------------------------------------------------------------------------------
What do you think the problem is about?

It is mandatory to set the value of UIData to a List, Array, ResultSet
or DataModel valueBinding, from this are the rows build.

Hi Onur,
Having dynamic columns, and setting the DataModel are two unrelated
issues. The first controls the "width" of the table. The second controls
its "height" (ie the number of rows rendered).
Even when all the columns have only static text the table will still
render the number of rows corresponding to the number of objects in the
DataModel.
If you aren't providing a data model to the table, then that would
explain why your table only has headers! Without a datamodel, how is the
table supposed to know how many rows to render?

Simon,

Have you looked at using <t:columns> for creating dynamic sets of
columns? If nothing else, you can use this a reference code.

Thank you simon,
I've already tried to set unique id. I think we are missing something.
Maybe expert team members may show the way to do it. I've read all the
forum postings before asking here. There is no exact answer about this
topic. Maybe UIData component doesn't not support dynamic columns. Is
it madatory to set DataModel attribute of UIData.
Best regards,
Onur

It looks ok to me.
One things you should do is explicitly assign an id to each component
you create. All programmatically-created components should do this. And
of course you need to invent some id-generator code to ensure that the
assigned ids are all unique. However I doubt that this is the cause of
your problem...
