Problems with sequence-item
I get errors when sequence-item is being called to list the contents of a folder E.g. <dtml-in "(1,2,3)" reverse> <dtml-var sequence-item> </dtml-in> correctly outputs 3 2 1 When I do <dtml-in "folder.objectValues()"> <dtml-var id> </dtml-in> it correctly outputs all ids in the folder. But <dtml-in "folder.objectValues()"> <dtml-var sequence-item> </dtml-in> will fail with an error Error Type: AttributeError Error Value: __call__ What am I doing wrong ?

Your problem appears to be in the using of objectValues(). This returns the actual objects. So, in the second loop (<dtml-var id>) you are referencing the 'id' member of each object. Nothing wrong there. However, in the third loop (<dtml-var sequence-item>) you are trying to render the object itself. This will 'call' each object, which some of them (obviously) object to. (No pun intended) If you want to render all the DTML Documents and DTML Methods in the folder , try something like: <dtml-in "folder.objectValues(['DTML Document', 'DTML Method'])"> <dtml-var sequence-item> </dtml-in> but this could get very messy with a large folder.

Have a better one, Curtis Maloney

In this example, <dtml-var sequence-item> is actually trying to call the items in the folder. In this case, at least one of the items is not callable ( like another folder). If you did something like this: <dtml-in "folder.objectValues('DTML Method')"> <dtml-var sequence-item> </dtml-in> You would see the results of 'viewing' or calling every DTML Method in folder. Mark

Had already tried that, but it doesn't work. I have 8 DTML Documents in a folder called artikelen. <dtml-in "artikelen.objectValues('DTML Document')"> <dtml-var sequence-item> </dtml-in> Fails with the error: Error Type: AttributeError Error Value: __call__ I am really clueless....

Any chance you could post the WHOLE traceback, so we might be able to see which object it's choking on?

I thought at first this might be a permission problem, but after browsing around the site. i'm pretty sure its a calling issue. its hard to say for sure given the lack of details. Taco, i'm pretty sure your objectValues on the addressen folder to fill in to fill in the addresses of the artiklen document. zope renders these subtemplates slightly differently than a template called directly by the browser, when you're calling the addressen subobject from the document call it like this <dtml-var "addressen.YOURADDRESS(_.None, _)"> or in a <dtml-in> <dtml-let x=sequence-item> <dtml-var "x(_.None,_)"> </dtml-let> if that doesn't solve it for you, than it would be helpful to have the relevant src of the document. i tried without success to duplicate the exact same error, but i'm pretty sure that the problem has something to do with this.

Thank you all for helping me out. The hints got me almost there. I have one unsolved mystery left. What I am trying to do is print the titles from the DTML Documents in the 'artikelen' folder (and actually another property called 'inleiding'. I believe the code below should do this, but it does not work. It returns 'Zope' instead of the title. If I use the 'inleiding' property it reports that it does not exist. If I just use sequence-item it returns the complete item ok. Any clues ? Thanks, Taco http://www.gezondheidskrant.nl:8080/mainframe : <dtml-let articleList="[]"> <dtml-in "artikelen.objectValues(['DTML Document'])" sort=publiceren_vanaf> <dtml-call "articleList.append(_['sequence-item'])"> </dtml-in> <dtml-in "articleList[-4:]" reverse> <dtml-let theDocument=sequence-item> <dtml-var "theDocument.title"> <dtml-var "theDocument.inleiding"> </dtml-let> </dtml-in> </dtml-let> ________________________________________________________ 1stUp.com - Free the Web Get your free Internet access at http://www.1stUp.com
