The changes would basically be that in accept() more data is collected, 
as is in the XHTML version, so that at least the ID and the data is 
accessible.
 Then the label could be composed of the id and/or the data. The format 
could eventually be specifyed by an option object passed to the 
constructor (as in the XHTML case).

ezcWorkflowNodeVariableSet vs. $execution->setVariable()?

<div><span>Good Morning. ezcWorkflowNodeVariableSet vs.

Explicit line breaks are not possible (yet) in graph. The text fitting
algorithm in the driver base class does not allow this.

UserInput Component - how to define a checkbox

I'm using eZ components for the first time and am trying to get to
grips with the UserInput component.  I have read the tutorials and the
api fairly thoroughly.

I have a checkbox on my form which returns a short string if checked.
I have defined in in the $definitions as

'administrator' => new ezcInputFormDefinitionElement(
			         ezcInputFormDefinitionElement::OPTIONAL,'string')

When I then check if the form is valid, when the checkbox is not
checked, even if all the other fields validate OK, then it returns
false.  With the checkbox fieldname (administrator) in the
invalidProperties array.

According to the api, the OPTIONAL parameter should mean that the
field does not have to be in the form (which it isn't as unchecked
checkboxes do not get passed to the program in the globals).  It looks
to me as if this is documented incorrectly, that the field does in
fact have to be present in $_POST/$_GET. Which means that the
component cannot be used with checkboxes.

Am I correct in thinking that this component is not behaving as
documented?  Have I defined the ezcInputFormDefinititionElement
incorrectly or is there somewhere else where I'm going wrong?

Any help would be much appreciated, this problem is a show-stopper for
me with this component.

regards
Hilary

I tried to use different applications with WebDAV shares and for me it 
behaves like a normal drive (I can open files from it, edit and then 
save). I tried with Paint, IrfanView, Photoshop (but did not try yet 
with Word).

One thing which I noticed is that working with WebDAV shares in this way 
is very slow (5 times slower even). I think it is better to work on a 
local copy of the file, then upload it to WebDAV.

ezcPersistentObject

<div>

<p>Hi everybody,<br><br>
We have a little problem with the ezcPeristentObject on our project and we don't know where is the mistake. With an outside look, someone could help us.<br><br>
We have made a script to look up in the database and generate a schema XML file. Then we use the persistent object database tie in to generate the classes and definitions. One of our table in the database contains a field of type datetime, and when we try to save an object with the persistent session, the datetime field is never saved : we have the following value in the database : "0000-00-00 00:00:00.0". So we have looked in the definition and in the class, and the datetime field is considered as an integer (it must be a string).<br><br>
There's nothing on the documentation about this and I was wondering if we have made a mistake.<br><br>
The database is MySQL 5.x and eZComponents 2008.2.2.<br><br><br>

database specific time formats are not supported by the database
abstraction components in eZ Components, since they are not portable.
Some databases use different formats and some even do not support
special time fields at all.#

Therefore you should use integer fields to store date/time information.

Toby
