Item5940: SlideShowPlugin does not work with EditChapterPlugin enabled in TWiki 4.2.2 and Foswiki 1.0.4/1.0.5

-- WolfMarbach - 18 Aug 2008

I upgraded me TWiki to Version 4.2.2 and found it strange that the SlideShowPlugin didn't work. Finally I found that it doesn't work with the EditChapterPlugin enabled. There might be a bug in the EditChapterPlugin which interferes with the use of an anchor in the SldeShowPlugin.

I want to say, that this problem remains in Foswiki 1.0.4/1.0.5 . At the time I reported Tasks.Item1499 I didn't thought about testing other plugins and was irritated, that on my fresh Foswiki 1.0.5 installation the SlideShowPlugin works and some days later, some more plugins installed, it doesn't work.

Adding to my description in Tasks.Item1499 I get the "Edit this chapter"-pencil for every Heading, if I move my mouse over it. At this time I missed this fact.

If the bug isn't so easy to fix, could be there some words on the documentation of the two plugins? Or can't be there a feature to disable the EditChapterPlugin in every Topic where a %STARTSLIDESHOW% is matchable?

Is there a feature to disable plugins only on a part of a topic, not for the whole topic?

Many Thanks in advance

SlideShowPlugin is a default plugin that turns sections into slide.

EditChapter makes chapters editable.

I think EditChapterPlugin need to be made aware of SlideShowPlugin since it is an extra plugin where SlideShowPlugin is a default that EditChapterPlugin can asume will be activated on 95%+ of Foswikis.

It should be a simple thing to make EditChapterPlugin aware that it should turn itself off when the slideshow=on URL parameter is present.

did this combination use to work in twiki? if so, we should identify what caused things to break.

asking for feedback from WolfMarbach and StephaniePlatz if this is broken in twiki as well or only on foswiki? and if broken on twiki, too, which versions did it not work on? which versions of twiki did it work on? thanks.

I'm sorry for my late answer. I don't know if this problem occurs on older TWikis, I have it only tested on Foswiki 1.0.4 and 1.0.5

But I detected, that if you add SlideShowPlugin in Configure to PluginsOrder at the end and EditChapterPlugin isn't in this list(or it is after SlideShowPlugin), it renders correct.

Would it be better to add this instruction to the documentation of SlideShowPlugin and EditChapterPlugin or to make a hard-coded bugfix in EditChapterPlugin?

And I don't know, if SlideShowPlugin will break other Plugins, if it's out of the normal alphabetical order, but I don't think so.

This is completely normal, and adding SlideShowPlugin to the Plugin order is the right solution. See Item9805.
