creating datatable with dynamical columns
Hi,
I need to create AjaxFallbackDefaultDataTable with dynamical columns. I am
reading columns from database and creating AjaxFallbackDefaultDataTable with
this info. I have classes DataTable and DataRow like .net's data layer
structure. DataTable have DataRows in ArrayList and DataRows have DataColumns
in ArrayList. I am defining DataRow as modelObject. I am reaching column value
like this:
((DataRow)dataTable.getRow(rowIndex)).get/String/Decimal/Date("columnName");.
Wicket searching set/getColumnName() in the modelObject and these classes and
functions have been finalized. It looks like, there is no way to create
dataTable with dynamical columns. If any way you know can you explain?

rsrt.respond(getRequestCycle());
This last line, rsrt.respond is what you shouldn't do.

No, There is no error at logs. I have tried to do with wicket but I cant. So I
have done with this way. This link is org.apache.wicket.markup.html.link.Link
and in the org.apache.wicket.markup.html.panel.Panel. And the panel in the
org.apache.wicket.markup.html.WebPage

That's what I used to use, but it gives the same error. Do you not get
the error in the logs. The error doesn't stop it from working, but I
still would like to do it correctly according to Wicket.

or something like this:
new Link()
{
onclick()
{
CharSequence discounts = DataBase.getInstance()
.exportDiscounts();
ResourceStreamRequestTarget rsrt = new ResourceStreamRequestTarget(new
StringResourceStream(discounts, "text/csv"));
rsrt.setFileName(name);
setRequestTarget(rsrt)
}
}
Maybe we should give ResourceStreanRequestTarget 1 extra constructor
with
the file name..
setRequestTarget(new ResourceStreamRequestTarget(new
StringResourceStream(discounts, "text/csv",name)))
