Re-3: [Zope] Problem with zope and long strings - SOS

[jens.walte at kk.net]

Hi,

Zope/Python does not break long strings.
This little PythonScript show's it:
-----------------------------------------------
longstring = ""
x = "1234567890 "
for i in range(1000): longstring+=x

print """<script language="JavaScript">"""
print "alert('%s');" % longstring
print """</script>"""
return printed
-----------------------------------------------
But DTML produces many breaks..
It's nearly unpossible to produce fine DTML-sourcecode
without line breaks.

so use python! ;)
otherwise you can use a visible/hidden <div> to show your error-message.

regards
Jens Walte
