Well, it > blows up on re-using a link after the BACK button is used. so far I didn't bother about the back-button, the only workaround is to avoid the use of the back-button or to fix the problem by adding #registerObjectForCallback: at all the required places.

As the comment says, Magritte-All-lr.19 is broken, try loading Magritte-All-lr.19 and maybe SmallWiki2-All-lr.72. I am using Seaside2.6a1-avi.26, but that shouldn't matter. > But now, as soon as any link is chosen, the same error appears: > MessageNotUnderstood: SW2Page>>filename > * SW2Page(Object)>>doesNotUnderstand: #filename > > Is this fixable? Should I just pack my bags and go home? This is certainly fixable. Could you send a full stack trace? I can't reproduce this problem. Cheers, Lukas -- Lukas Renggli http://www.lukas-renggli.ch

Re: smallwiki und bilder

by Lukas Renggli

hi rafael, > wir machen im ADL den import vom swiki zu smallwiki 2. im swiki > kann man seiten erstellen, wo text und mehrere bilder gemischt > sind. kann man das auch in smallwiki 2? add your images as files (probably as children to its page) to the wiki tree and then link them using the standard syntax. Embedding is possible of course, but you have to tell the internal link to do so: anInternalLink embed: true Btw, in SmallWiki 2 not only images can be embedded, but also other pages, Seaside components and applications, etc. Cheers, Lukas -- Lukas Renggli http://www.lukas-renggli.ch

We are searching for elements with a visitor, but the refactoring itself happens independently. We need the knowledge about the parent of each DocumentItem while doing the refactoring (e.g. for removing). We can not do the refactoring with a visitor, because we want to present the search result to the user for selection. If we have to deal with this without back links, we need to collect the parents in the search-visitor and keep this information temporarely in the search result. This would not be nice as it is not the responsibility of the search result to know the parent of the found elements. Daria & Norbert

Re: Owner of SW2WikiObjects

Hi Daria & Norbert, > For the refactoring of pages we need to know the (direct) parent of > each SW2WikiObject (especially SW2DocumentItem subclasses). > SW2WikiObject has the instance variable owner, but it is not always > used. I don't see any i-var called owner in my code. I think you are talking about the empty accessors in SW2WikiObject? These accessors are implemented in SW2InternalLink, since internal links need to know their page to do the lookup of the path. So, in this case the owner is not the parent, but the containing structure. > We thought it would may be of general interest to always have this > attribute. Would it be possible to get this feature? In my opinion, back-links are generally a bad thing and therefor I try to avoid them whenever possible. Have a look at the i-var parent in SW2Structure and SW2Decoration and all the hassle around this. Back-links duplicate information and it makes several things, such as copying, more difficlut. Actually, while traversing a composite with a visitor you have given all the parent nodes implicilty in the context-stack. I don't suggest that you are using the context, but to keep the last node in an i-var or build up a stack of the current path to your visited nodes.

What about setting it in SW2Visitor and make sure that all subclasses do a propre super call? I think the default ones should do this anyway.

Bug in SWTemplateBodyMenu?

by Markus Fritsche

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi! When I added a menu to my wiki and set it's preference to always show the whole structure beginning from the wiki root (via the CompenentEditor). An edit of the entry page results in an infinite recursion of deepCopy; as far as I can tell, the new page created gets a copy of the preferences, and with this special preference turned on, there's a reference loop which causes the recursion...
