IDEA! We are upgrading from Foswiki 1.0.10 to 1.1.3.

In one of our applications (for ActionTrackerPlugin), we have a date field defined, where we provide a default value which lies 1 week ahead. We use %CALC to calculate this date:

[...]

%FORMELEMENT{
name="Due"
type="date"
dateformat="%Y-%m-%d"
size="9"
title="Due date:"
default="%CALC{$FORMATTIME($TIMEADD($TODAY(),1,week),$year-$month-$day)}%"
disabled="%IF{"$WIKINAME='WikiGuest'" then="on"}%"
hint="Format: yyyy-mm-dd; empty if yet unknown."
}%

[...]

Now the problem is, that with this CALC statement, the whole form element stopped from being rendered.

I don't know, if this actually is a bug to be fixed or if it's a feature to which I have to adjust my code to make it work again...

On my computer with FW 1.1.3 this is rendered as:
Due date:

What doesn't work?

Well, er, yes, now that you say it...

You are right. In a clean environment, there is no issue with this. But (and I'm sorry for this one...) when we put this FORMELEMENT definition into a template definition of CommentPlugin (like in Item10826), then the whole %FORMELEMENT ... gets printed in plain text:


%STARTFORM{
name="action_tracker_data"
action="save"
topic="%WEB%.ToDoList"
anchor="Action_Tracker_Data"
}%
%COMMENT{type="action_tracker_data" noform="on" templatetopic="%WEB%.%TOPIC%"}% 
%ENDFORM%

<verbatim style="display: none">
%TMPL:DEF{PROMPT:action_tracker_data}%
<div class="foswikiFormSteps">
<div class="foswikiFormStep">
<input type="hidden" name="comment_action" value="save" />
<input type="hidden" name="comment_type" value="action_tracker_data" />
<input type="hidden" name="comment_templatetopic" value="%WEB%.%TOPIC%"  />

%FORMELEMENT{
name="Due"
type="date"
dateformat="%Y-%m-%d"
size="9"
default="%CALC{$FORMATTIME($TIMEADD($TODAY(),1,week),$year-$month-$day)}%"
title="Due date:"
disabled="%IF{"$WIKINAME='WikiGuest'" then="on"}%"
hint="Format: yyyy-mm-dd; empty if undefined yet."
}%

</div>
</div>
%TMPL:END%
%POS:AFTER%%TMPL:END%
</verbatim>

Moving the FORMELEMENT out of the %TMPL:DEF block will also move it away from the <div blocks where it used to be embedded and the order of the fields gets disturbed:


%STARTFORM{
name="action_tracker_data"
action="save"
topic="%WEB%.ToDoList"
anchor="Action_Tracker_Data"
}%
%COMMENT{type="action_tracker_data" noform="on" templatetopic="%WEB%.%TOPIC%"}% 
%ENDFORM%

%FORMELEMENT{
name="Due"
type="date"
dateformat="%Y-%m-%d"
size="9"
default="%CALC{$FORMATTIME($TIMEADD($TODAY(),1,week),$year-$month-$day)}%"
title="Due date:"
disabled="%IF{"$WIKINAME='WikiGuest'" then="on"}%"
hint="Format: yyyy-mm-dd; empty if undefined yet."
}%

<verbatim style="display: none">
%TMPL:DEF{PROMPT:action_tracker_data}%
<div class="foswikiFormSteps">
<div class="foswikiFormStep">
<input type="hidden" name="comment_action" value="save" />
<input type="hidden" name="comment_type" value="action_tracker_data" />
<input type="hidden" name="comment_templatetopic" value="%WEB%.%TOPIC%"  />
</div>
</div>
%TMPL:END%
%POS:AFTER%%TMPL:END%
</verbatim>

Now it is getting really complex. Especially SpreadSheetPlugin can behave unpredictably with other plugins.

I advice you to use DateTimePlugin for this so you can write:
default="%DATETIME{incdays="7"}%"

Thank you very much for this hint, Arthur!

I'm setting this bug to "No action required"...
