When I click the test1 input button, the writeContent should writes
"function not implemented" but when I return to the SomeClass Page, it
should uses the SomeClass writeContent...
I tried to create a quick way to say short messages...

I preferred to not use __init__, I define the error before writeHTML...

No, i have a Form and a Process class, the process class are derivated
of the Form class, I test the variables using a method like this:
...
def writeHTML(self):
if not self.request().hasValue('somevalue'):
self.appendError('some error')
if self.request().('another_value')=='-1':
self.appendError('some another error')
baseClass.writeHTML(self)
def writeContent(self):
if self.hasError():
base.writeContent(self)
return
... do something else ...
...
So I defined the appendError method and the hasError, this methods
control the ._error list... This is the methods:
def appendError(self, mensagem):
try:
error=self._error
except AttributeError:
error=[]
error.append(mensagem)
self._error=error
def hasError(self):
try:
error=self._error
except AttributeError:
error=None
if not error:
return False
else:
return True
Understand? My problem is that the error is not cleaned throught
requests... I enter the section with a error one time, so I return, fix
the error and submit again, the erros still existing...
Is there a way to not cache this error without need to clean the error
on the Form? I having the same problem with all atributes I define...
I have 2 sites, a SiteA and a SiteB, the SiteA is the running system,
the SiteB is a alpha test, I develop the system in the SiteB, the SiteA
access a database_backup, the SiteB access a database... When I access
the SiteA and so go to SiteB, the database attribute stored is the
database_backup (from SiteA)...
I want to automatically clean this attributes, the WebWare doc have
something about, but the section appoints to a fixme...
If there is no way, I will clean it manually, but before I want to know
if there is no way...
thanks for the patience :) and for the help! Seeeya
