[PR] Just a little error, but i don't understand why !

Hi everybody,

I’ve a little problem with my code! I try to generate html code starting
from PIER. When I launch my widget (SPG tool) the nextPutAll method
generates an error, but I don't understand why. Can you help me to
understand that?

Thanks in advance

My project name in squeaksource.com : StaticPierGen

Sample of my error:

MessageNotUnderstood: UndefinedObject>>nextPutAll:
Debug Full Stack
• UndefinedObject(Object)>>doesNotUnderstand: #nextPutAll:
nil
temps aMessage nextPutAll: 'Welcome to Pier (formerly called SmallWiki
2), the next generation of a fully extensibl...etc...
• WAHtmlStreamDocument>>nextPutAll:

temps aString 'Welcome to Pier (formerly called SmallWiki 2), the next

inst vars stream nil
htmlEncoder nil
urlEncoder nil

As the error says you are sending the message #nextPutAll: to nil,  
the instance of UndefinedObject. So you need to properly setup  
WAHtmlStreamDocument so that it references an instance of WriteStream.

Cheers,
Lukas

read the stack
you send a message to nil

> • UndefinedObject(Object)>>doesNotUnderstand: #nextPutAll:

Hello,

I always have the same problem with the initialization of WriteStream.
In fact I do not see how to initialize it. I tested with:

# myVisitor renderer: (WAStaticHtmlCanvas root: WAHtmlRoot new).
# myVisitor renderer document stream: String new writeStream.

But I do not obtain the result that I want. Moreover, I have this error
since an update of PIER and SEASIDE. According to what I saw, the
WAStaticHtmlCanvas class was modified. Could you give me information?

Another question: I would like to know if it is possible to add a link
towards a file (ex: afile.zip) in PIER to download it from the server?

Example with a traditional server HTML: download this file

# <a href=’http://127.0.0.1:8080/seaside/pier/myFile.zip’> download this
file </a>


Thank you in advance for your answers.

Pierre

Try to use

        WAStaticHtmlCanvas document: (WAHtmlStreamDocument new
                stream: String new writeStream)

I've never used WAHtmlStreamDocument. Could be even broken in the  
latest Seaside.

Hi !

Thanks for your answer.
I tried your suggestion but the problem is the same. When i launch my
visitor, i obtain a basic stream.
I will try to find another solution.

For my link problem i tried with this :

url: (html context urlForDocument: (WACachedDocument fileName:
'.\staticPier.zip') asMIMEDocument content);
