Re: Dynamic form
And what is the best way to create such a dynamic form? Using Delegate component or modifying beaneditform? Or maybe there is better approach? I tried to write it using Delegate and I have a problem - I can't get component instance from ComponentSource - Exception: org.apache.tapestry5.internal.services.RenderQueueException Render queue error in BeginRender[Step:dynamicformfield.delegate]: Failure reading parameter 'to' of component Step:dynamicformfield.delegate: Unable to resolve 'textfield' to a known page name.

[T5.2] JavaScript combination
A few questions: Is there any documentation of the new JavaScript combination functionality added to fix TAP5-769 in 5.2, specifically about stacks? I can't see any, but before I dive into code/javadoc I thought I'd ask. Why aren't the prototype & scriptaculous libraries combined into a stack by default? What's the status of minifying css & js? Thanks, Andy.
T5.1: componentSource with an activation context
Hi, Is there a way to create Pages and initialise their activation context at a service level? ComponentSource can give me Component instances but casting it to my page instance results in a ClassCastException due to the different classloaders. Is there a way I can set an activation/event context in this component using existing Tapestry services? This thread does mention that I could use an interface defined outside of the component/page/mixin packages but it feels like there might be a way to hook into the existing tapestry context behaviour... http://tapestry.1045711.n5.nabble.com/Tap-5-0-11-How-to-get-page-instance-from-page-tt2416695.html#none Thanks in advance for any help.

Re: Blog post about T5 data access layer implementation in GAE
Hi Dmitry, You mention there are two ways to communicate with the GAE datastore from Java, but there is at least one more: http://code.google.com/p/objectify-appengine/ I haven't looked into it in detail, but thought I'd mention it for yourself and others who might have an interest. mrg On Wed, Sep 1, 2010 at 3:54 PM, Dmitry Gusev wrote: > FYI > > http://dmitrygusev.blogspot.com/2010/09/gae-and-tapestry5-data-access-layer.html > > -- > Dmitry Gusev > > AnjLab Team > http://anjlab.com > - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

Hi,
Hi!
I have migrated my application recently from Tapestry 5.0.18 to 5.1.0.5.

sessionState.setSessionExpired(false);

I guess you were a Tapestry 4 user. :)
If you're in page or event handler method, the right way of doing a
redirect is to return a java.net.URL instance.
By the way, you can inject the Request and Response directly without usin
RequestGlobals.
My requirement is if session fails, redirect it to start page where it
will show the message. Please help me to resolve this issue.
This is better implemented in a RequestFilter. There you can use
sendRedirect() without problems.

Re: NPE in getSession of an anonymous Request class?
Well it boiled down to the commented out line below. I changed the forward to
the requestGlobals one and it works.
try
{
requestGlobals.getResponse().sendRedirect("nontapestrypage.html");
//request.getRequestDispatcher("nontapestrypage.html").forward(request,
response);
return null;
} finally {
redirect = null;
}

I was handling session in my application previously (5.0.18) as:
If (!visitExists) {

but this is not working anymore in 5.1.0.5. I tried with httpServletResponse

My requirement is if session fails, redirect it to start page where it will
show the message. Please help me to resolve this issue.

Re: [T5.2] Tapestry IoC Configuration (remove?)
Hi Howard and all,
thanks for your reply. I am always impressed how flexible Tapestry is.
The activation of the compression for JSON worked, but I was struck
by TAP5-469 and started some research.
Regarding your blog post
(http://tapestryjava.blogspot.com/2009/04/is-gzip-compression-compatible-with.html):
I tried several other combinations that worked fine, so I'm convinced
that GZIP compression in combination with JSON content basically works.
Thus, the error seems to be somewhere in the Tapestry code. My research
has shown that the Tapestry gzip stream sometimes does not finish
correctly when sending json. Therefore, the data is broken when it
arrives at the client. I have now solved the problem the following way
and it works very well:
I have changed my event handler from:
JSONObject onAction() {return getJson();}
to:
StreamResponse onAction() {return new JSONResponse(getJson());}
and created the following wrapper:
public class JSONResponse implements StreamResponse {
private static final int HEADER_SIZE = 20;
private static final int MIN_DATA_SIZE = 512;
private static final String CHARSET = "UTF-8";
private byte[] data;
private boolean compress;
public JSONResponse(JSONCollection json) {
try {
data = json.toCompactString().getBytes(CHARSET);
compress = data.length >= MIN_DATA_SIZE;
} catch (UnsupportedEncodingException e) {
// should never happen!
}
}
@Override
public String getContentType() {
return "application/json; charset="+CHARSET;
}
@Override
public InputStream getStream() throws IOException {
if (!compress) {
return new ByteArrayInputStream(data);
}
ByteArrayOutputStream out = new ByteArrayOutputStream(
expectedCompressedSize(data.length));
GZIPOutputStream gzip = new GZIPOutputStream(out);
gzip.write(data);
gzip.close();
byte[] gzipedData = out.toByteArray();
return new ByteArrayInputStream(gzipedData);
}
@Override
public void prepareResponse(Response response) {
if (compress) {
response.setHeader("Content-Encoding", "gzip");
}
}
private int expectedCompressedSize(int size) {
return (size >> 2) + HEADER_SIZE;
}
}
Regards,
Michael

It was disabled because it cause problems in some browsers.
