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?

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

I have a problem about creating dynamic HtmlDataTable component. The

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;
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...
