[Zope] Adding ZClass Instances via DTML

[Nico Grubert]

hello,

I try to add a new instance of a simple zclass "BuchClass" via dtml.
I use a dtml-method "view_html" containing some code like this:

<FORM ACTION="add_html" METHOD=post enctype="multipart/form-data">
<td>ID: <input type=text name=newID></td>
     <input type=submit value="Add">
</form>

This dtml-method calls another dtml-method "add_dtml" which looks like
this:

 <dtml-call "REQUEST.set('id','<dtml-var newID>')">
 <dtml-with "manage_addProduct['BuchProduct']">
   <dtml-call "BuchClass_add(_.None,_, NoRedir=1)">
 </dtml-with>

Calling up "add_dtml" which gets the variable "newID" will bring me this
error:
The id contains characters illegal in URLs. 
******************************************************************
The id contains characters illegal in URLs.

************************************************************************************************


Replacing '<dtml-var newID>' with for example 'mynewObject' will add a
new zclass instance.
Should I make some changes in the constructor-method which contain this
codde?:

<!--#with "BuchClass.createInObjectManager(REQUEST['id'], REQUEST)"-->
       <!--#call "propertysheets.buchinfo.manage_editProperties(
                  REQUEST)"-->
<!--#/with-->
<dtml-comment>
       <dtml-call "REQUEST.set('id','newObId')">
<dtml-if NoRedir>
<dtml-else>
<!--#if DestinationURL-->
 <!--#call "RESPONSE.redirect(
       DestinationURL+'/manage_workspace')"-->
<!--#else-->
    <!--#call "RESPONSE.redirect(
           URL2+'/manage_workspace')"-->
<!--#/if-->
<!--#/if-->
