SID-00507: Strange Calc Behavior

I am trying to port a calc function that I wrote for TWIKI 4.1 over to 4.3 and it no longer works correctly.

Basically, I have an automated time sheet system that generates a link to a Twiki page every week.

The system works fine if you are in the Main web but if the user goes to another web it says it can't find a page that exists.

I traced it down to the retrieval of the week variable.

First I set a calc variable for the week number:

CALC{" $SET( week, $INT($IF($REPLACE(0%SERVERTIME{$day}%0000,-5,5)==0, $REPLACE(00%SERVERTIME{$day}%,1,3), %SERVERTIME{$day}%)/8) )"}%%CALC{"$SET(week, $IF( $GET(week) == 4 ,3 , $GET(week) ))"}%%CALC{" $SET( week, $INT($GET(week)+1) )"}%

Then I try to check and see if the page exists, if it does then I simply return a link to it and hide some other content using a div tag, if it doesn't then I return a div object that shows some content so I can do something else:

%CALC{$IF($EXISTS(%USERNAME%%SERVERTIME{"$mon$ye"}%W$GET(week)),%ICON{"index"}% %USERNAME%%SERVERTIME{$mon$ye}%W$GET(week)<div style="display:none;">, <div>)}%

This works just fine if I am in the main web, but if I navigate to another Web it says it can no longer find the page. I found out the reason was beceause of the calc variable "week". If I remove that and instead manually specify the number it should return it can always find the page regardless of what web I am in.

Does anyone have a clue as to what's happening here?

Update: So it turns out that if I have an explicit reference to the topic in question anywhere in the topic I am editing this problem goes away.

For example, if the code I showed above results in MyNameAug09W4 twiki will calim that the topic doesn't exist (even though it does). If I simply write Main.MyNameAug09W4 right below the code then all instances of MyNameAug09W4 apear as valid links (in other words Twiki acknoledges thier existance.

I never had this problem in 4.1. Is this a bug, or am I doing somthing wrong?

Discussion and Answer

Likely related to TWikibug:Item3889. Fix: Use a full Web.PageName specifier, e.g.
$EXISTS(%WEB%.%USERNAME%%SERVERTIME{"$mon$ye"}%W$GET(week))
