Preface

This bug is related to Item1990 which got fixed recently

Anyway, I decided to file a new bug for this issue, as the resulting problem is different now, although the origin can probably be found in the abovementioned bug.

Description

In our corporate Wiki we have several forms which use the combination of FormPlugin and CommentPlugin to generate text strings for topics which are read out by e.g. ActionTrackerPlugin or HolidaylistPlugin.

While these forms work nicely with a rather old version of FormPlugin (foswiki-formplugin_090317-197_all.deb), where bug Item1990 was not yet present, the most recent version is troublesome with the following form data post-processing:

Short example

Have a look at the HolidaylistPlugin syntax:
From - Until - Who - Occasion - Smilie
Only the fields "From" and "Who" are mandatory. If the others are not present, the " - " separator is also omitted. And this is where we used to use form field post-processing by means of hidden fields:

%FORMELEMENT{
name="Until"
type="date"
dateformat="%d %b %Y"
size="9"
title="End Date:"
disabled="%IF{"$WIKINAME='WikiGuest'" then="on"}%"
}%

%FORMELEMENT{
name="FormattedUntil"
type="hidden"
default=" - $Until"
condition="$Until=nonempty"
}%

Then, the TMPL:DEF{OUTPUT:holiday_data} line will rather use "URLPARAM{"FormattedUntil"}" rather than " - URLPARAM{"Until"}". This way we only write the parameter in the OUTPUT line, if it exists and omit the separator " - " when it's not.

Now, in the recent version, the URLPARAM data gets redirected in a way, that the hidden form field doesn't get expanded before redirection. So the result is that we get the unexpanded " - $Until" in the new entry rather than something like " - 04 Jun 2010".

Fixing the issue

In the full examples I show below, you see that it's very important for us to be able to do this post-processing of user-entered form data. If you have any suggestion how to workaround this issue, e.g. by any sort of delayed execution, please tell me.

Personally. I feel that this is a bug and not a feature, as it breaks existing applications.
