Uncaught exception when tried to return a StreamResponse
Hi Guys,
I want to export data in excel sheet, so I made a page class as the following without a template file(.tml)
public class ExportExcel {
.
.
.
StreamResponse OnActivate(){
List<User> users = userManager.getAllActiveUsers(); // break point here never got hit
return export(users);
}
public StreamResponse export(List<List<String>> rows) {
// some logic to export the data in .xls
}
}
And this is the error I got:
Page export/Excel did not generate any markup when rendered. This could be because its template file could not be located, or because a render phase method in the page prevented rendering.
And I am using this page link.
<t:pagelink t:page="export/excel"
title="message:export-label"/>
any idea what is the problem ?
Thanks in Advance,
Amr Hassanin

Here is a simple example with which you can compare
public class ExportXML {
StreamResponse onActivate(){
return new StreamResponse() {
@Override
public String getContentType() {
return "text/xml";
}
@Override
public InputStream getStream() throws IOException {
String xml = "<?xml version='1.0'?>\n" +
"<message>Hello</message>";
ByteArrayInputStream in = new ByteArrayInputStream(
xml.getBytes()
);
return in;
}
@Override
public void prepareResponse(Response response) {
}
};
}
}
BTW what tapestry version are you using( just to ensure we are dealing with tapestry5 :))
Also I remember one case where a developer had implemented StreamResponse as a public class in the pages sub-package. That can also lead to this issue.

Hi Amr
Are you sure your onActivate() is being called. BTW, your onActivate() has 'O' in uppercase. To avoid such typos I prefer the OnEvent annotation

Hi Amr
Are you sure your onActivate() is being called. BTW, your onActivate() has 'O' in uppercase. To avoid such typos I prefer the OnEvent annotation

RE: Uncaught exception when tried to return a StreamResponse
Posted by Amr Mohamed Mahmoud Hassanien <am...@ey.ae>.
Page link never renders correctly if the page name is not correct and it thankfully gives suggestions for the page name like this :
Render queue error in BeginRender[user/List:pagelink]: Unable to resolve 'exportExcel' to a known page name. Available page names: (blank), About, Contact, ExceptionReport, Forbidden, Index, Login, PropertyDisplayBlocks, PropertyEditBlocks, ServiceStatus, export/Excel, export/ExportExcel,
Still not fixed, any other possibilities?
