Yes and no, as written below. Sorry for the delay, but my wife reminds me that we are on holiday (Balconia :-)
No problem. Sorry for delay on my side, if you want to know the reason take a look at the end of this mail...
Well, make yourself comfortable... I want to create an editor component where a question along with a bunch of possible answers can be created and/or edited. Each question is localized in one or more languages, e.g. german, english, french. According to the role of the user or his task he may have complete rights (edit questions and answers, add or delete answers), may only translate from one language to another or may only view some languages. The user may hide some languages for convenience.
Ahh, still the same app :-)
So my solution approaches (not exhaustive): a) a html table hiding a column (= a language) via Ajax and WidgetState.INVISIBLE for each affected cell. This seems to be the best solution for accessibility but suffers from a bug [1] returning span's instead of td's.
I remember your report. I think we should try to tackle down this problem because it's really annoying and limiting.
It would be very helpful if you could come up with really minimal form definition and template that shows buggy behaviour and create issue in JIRA. This could become a start point for debugging and fixing it.
My GSoC project ends in a few days and even though I'll continue my work on expression and object model handling in Cocoon I'll have more free time to help others. Of course I don't make any promises, we don't know in advance if this issue is serious or not.
b) a html table where the hiding is done via deleting and adding rows. There's a problem reloading the data when the user wants to see a hidden language again and with preventing deletion of database entries.
You see yourself that it's hacky. Don't even think about such solution ;-)
c) a html table where the hiding is done via client-side javascript and manipulating css styles (one class per column). I have repressed the problems with this.
Less hacky but I really prefer a) option.
d) a table made of div's instead of a classical table. Is a work-around for a) but is bad for screenreaders. And I didn't test if span's are returned or div's. In the mind's eye I have something like tabs for each language, variable in width depending on the number of languages displayed. The optimum would be a scrollable area for the answer cells - displaying 10 languages would result in rather narrow columns otherwise. And with 40 possible answers the questions should be visible, too, as seen in Excel's "fix window" feature. Additionally when a language is hidden you may redisplay it by choosing it from a drop-down-menu. Reordering columns aka languages is also one of my dreams.
I think that everything is possible to do with current CForms as long as you make WidgetState.INVISIBLE working.
BTW: It seems TeeTransformer has a bug - tags like <br/> are converted in the output to <br> missing the closing element.
What about JIRA issue?
