[T5] 5.1.0.1 RC, rendering of some views produces stacktrace
Hi,
We are constantly getting this stacktrace on some of our views. Nothing, and
I mean nothing else is visible. The normal T5 error page doesn't come up
etc. Only this stacktrace. Using 5.1.0.1-20090305.090208-13 everything works
ok.
Does anyone know how to trace this or dig deeper?

Hi, and thanks for the input.
I'll debug it, but currently other project that I'm working on is nearing
release so I'm tied to that one pretty much atm.
And I promise I'll try to get the alpha and RC names correctly in the future
;)

One suggestion ... download and attach the source.
You could step through from the beginning of the request (can be tricky to
trace from the beginning with all the Javassist).
Or - at a minimum, you could jump to AbstractMarkupModel.java:94 and work
your way from there.

Re: [T5] 5.1.0.1 RC, rendering of some views produces stacktrace
Posted by Howard Lewis Ship <hl...@gmail.com>.
5.1.0.1 is not a release candidate. It's out there for exposure as an
alpha release (the vote isn't even completed yet!)
It looks like an issue with how null attributes are treated; assigning
an attribute (of a DOM Element) the value null is supposed to remove
the attribute entirely but it looks like that's not happening,
resulting in a later NPE while rendering.

Re: [T5] 5.1.0.1 RC, rendering of some views produces stacktrace
Posted by Ciaran Wood <ci...@gamesys.co.uk>.
I've had this problem before as well, in my case it was related to a Label
component trying to render a label for a RadioGroup. Inside beginRender of
the Label component, it does this:
labelElement.forceAttributes("for", fieldId, "id", fieldId + ":label");
In my case, fieldId was null (as RadioGroup implements ClientElement but its
getClientId() method returns null). In 5.1.0.1, a change meant that an
attribute with a null value was saved in the Element, so when the
Attribute.render() method was called, a null was passed as the value to
encodeQuoted() on the markup model.
In my case, the solution was to not use the Label component for the
RadioGroup, but just have a normal <label> tag in my template.

Re: [T5] 5.1.0.1 RC, rendering of some views produces stacktrace
Posted by Ville Virtanen <vi...@cerion.fi>.
Ok, now I had time to look it little closer:
In the particular view I'm generating lazy initialization exp and observe
T5:
The String content is null and thus of course generates npe at that point.
the last encoded string (or one of those) is t-omitted-frame, so it actually
crashes somewhere when rendering the own T5 error page?
Anyway, I don't have the required insight to trace the T5 rendering
mechanisms quickly, and unfortunately just now I don't even have the time to
make a view that reproduces it. (This does not happen under all
circumstances.)
I'll be back when I have time (if it is not solved yet) but atm my work is
too crazy...

Code that crashes: (AbstractMarkupModel, 94)
public void encodeQuoted(String content, StringBuilder builder)
{
int length = content.length(); <-------
