Re: More migration issues, 5.0.18 - 5.1.0.2
This only seems to affect some people ... I suspect it may only occur
when an Apache server is between the browser and the servlet
container. Can you confirm?
FYI, if it helps you at all I am running 5.1.0.0 in production Apache 2 - AJP
connector - Tomcat 6, I get only the occasional Gzip error in the logs, I am
holding off upgrading to 5.1.0.2.

I'm sorry and surprised you are having so much trouble.
I'm rather surprised too, the 5.0.x migrations (post .10) were always pretty
easy. I think I must have gotten complacent about Tapestry alpha status because
T5.0.11+ never really felt like alpha software to me. ;-) (oh, and some of the
new features in 5.1 are very appealing which is probably why migrating now was
so tempting!)
Anyway, the first issue is with our checkbox components that do an
Ajax call when checked or unchecked. They work fine if Gzip compression
is switched off, but if it's enabled the Ajax.Request hits the
onException block with this error message TypeError: response is
null. The server event handler is being called correctly and returning
the correct JSONObject, but the responseText is empty and responseXML,
responseJSON, and headerJSON are all null even though the status code
is 200. My guess that the JSONObject is being compressed and it
shouldn't be. Should I raise a JIRA for this, or am I mistaken here?
There's an existing JIRA issue, with a workaround.

Currently I've only been testing in Jetty on my PC with no apache server in
sight. The workaround is probably okay until you want to release 5.1 so there's
some time for gathering more data. I know it sounds unlikely but could it be
OSX/XP even with the same browsers? I can ask someone to test this on OSX
tomorrow if that would help.
I also have a page that works fine with T5.0.18 but breaks in
T5.1.0.2 and I have no idea why - curiously, if I have gzip compression
I don't see the stacktrace in the browser, but I get Content Encoding
Error, The page you are trying to view cannot be shown because it
uses an invalid or unsupported form of compression. From Firefox.
Here is the stack trace, in case anyone can make any sense of it:
An unexpected application exception has occurred.
Someone else has seen this as well.
void render(MarkupModel model, StringBuilder builder, MapString,
String namespaceURIToPrefix)
{
builder.append( );
builder.append(element.toPrefixedName(namespaceURIToPrefix,
namespace, name));
builder.append(=);
builder.append(model.getAttributeQuote());
model.encodeQuoted(value, builder); // line 69
builder.append(model.getAttributeQuote());
}
I think this I can chase down; something is wrong, the value should
never be null (it can be the empty string).
Did you see TAP5-635? It demonstrates a pretty bad consequence of this problem
and it took time to investigate so I hope it proves useful.
I think 636 might be a duplicate.
Thanks,
Andy.

Re: More migration issues, 5.0.18 - 5.1.0.2
Hi,
exatly the same problems we were having. I opened Jira issue because of
this:
https://issues.apache.org/jira/browse/TAP5-623
For us the main reason was because we had
label for=someid /
and then
t:if test=readmode
${value}
t:parameter name=else
t:textfield t:id=someid value=value /
/t:parameter
/t:if
Now with T5.0.18 this worked fine, but now dies in 5.1.0.2 if it is
readmode: (label gets null for parameter) - givin only some T5 internal
stacktrace or the unsupported form of compression..
Hope this helps,
- Ville

Thanks for this Ville it really helped me investigate this, still took 3 hours
to track it down. I've raised TAP5-635 for this because it turned out to be
related, but different - and also IMHO a valid use case. The stacktrace not
appearing with compression is another issue that needs resolving, but it's
minor.

I'm sorry and surprised you are having so much trouble.
I'm rather surprised too, the 5.0.x migrations (post .10) were always pretty
easy. I think I must have gotten complacent about Tapestry alpha status because
T5.0.11+ never really felt like alpha software to me. ;-) (oh, and some of the
new features in 5.1 are very appealing which is probably why migrating now was
so tempting!)
Anyway, the first issue is with our checkbox components that do an
Ajax call when checked or unchecked. They work fine if Gzip compression
is switched off, but if it's enabled the Ajax.Request hits the
onException block with this error message TypeError: response is
null. The server event handler is being called correctly and returning
the correct JSONObject, but the responseText is empty and responseXML,
responseJSON, and headerJSON are all null even though the status code
is 200. My guess that the JSONObject is being compressed and it
shouldn't be. Should I raise a JIRA for this, or am I mistaken here?
There's an existing JIRA issue, with a workaround.
https://issues.apache.org/jira/browse/TAP5-469
This only seems to affect some people ... I suspect it may only occur
when an Apache server is between the browser and the servlet
container. Can you confirm?
Currently I've only been testing in Jetty on my PC with no apache server in
sight. The workaround is probably okay until you want to release 5.1 so there's
some time for gathering more data. I know it sounds unlikely but could it be
OSX/XP even with the same browsers? I can ask someone to test this on OSX
tomorrow if that would help.
I also have a page that works fine with T5.0.18 but breaks in
T5.1.0.2 and I have no idea why - curiously, if I have gzip compression
I don't see the stacktrace in the browser, but I get Content Encoding
Error, The page you are trying to view cannot be shown because it
uses an invalid or unsupported form of compression. From Firefox.
Here is the stack trace, in case anyone can make any sense of it:
An unexpected application exception has occurred.
Someone else has seen this as well.
void render(MarkupModel model, StringBuilder builder, MapString,
String namespaceURIToPrefix)
{
builder.append( );
builder.append(element.toPrefixedName(namespaceURIToPrefix,
namespace, name));
builder.append(=);
builder.append(model.getAttributeQuote());
model.encodeQuoted(value, builder); // line 69
builder.append(model.getAttributeQuote());
}
I think this I can chase down; something is wrong, the value should
never be null (it can be the empty string).
Did you see TAP5-635? It demonstrates a pretty bad consequence of this problem
and it took time to investigate so I hope it proves useful.
I think 636 might be a duplicate.
Thanks,
Andy.
