Okay, I scanned ahead and didn't see a reply to this problem, so I'll take a stab at it. My first guess was that the problem with the following line: <dtml-var expr="selectDate_dtml(_.None,_,id='s',default=_.DateTime('2002/02/08'))"> was that with the default= syntax, the function is being passed as an address, rather than being called. However, that doesn't explain why it does work without a parameter. What I would suggest, if the default parameter is _always_ the result of a DateTime call, move the DateTime call into the python script and pass the default parameter to it. Hope that helps.

Hello everyone,

Sorry in advance for the elongated description of my problem, I just want to make sure I include all the information that might be required...

I have a dtml-method which will automaticly create date selection elements for a form. I pass it a default date in the form of a DateTime object. The value of the form elements is then initialised to this date.

Normally I just run it like this:

<dtml-var expr="selectDate_dtml(_.None,_,id='s',default=_.DateTime())">

Which sets the default date to the current one, and this works fine.

However, sometimes I want to initialise this bit of the form with a date extracted from an SQL query. I can access the field in question without a problem as a normal variable:

<dtml-var date_start>

displays as 2002/02/08

Now, I know that this format is appropriate to pass to the constructer for DateTime, because when I type in a date by hand, it works fine:

<dtml-var expr="selectDate_dtml(_.None,_,id='s',default=_.DateTime('2002/02/08'))">

However, when I pass the date_start variable to my dtml method as _.DateTime(date_start), I get the following error message:

---

Zope Error

Zope has encountered an error while publishing this resource.

Error Type: TypeError Error Value: unsupported operand type(s) for /

---

It looks like it isn't passing this variable to DateTime as a string, so how do I make it do that?

Thanks in advance for any help you can offer. - Paul
