[htmltmpl] (no subject)

[Jochen Cichon]

Hi,

i found a nice bug (that keeps me awake for about 3 hours...)


I have the following template:

<tmpl_if expr="(int(rand(2))==0">
  YES
<tmpl_else>
  NO
</tmpl_if>

which is not that complicated.



    NO
in the outut.


    YES
but if the results are different on the two runs you will get
    YES
    NO

... Whoops.


Any Ideas?




So why is ist pared twice? (sometimes!)

When you run the program, and the expr is evaluated to FASLSE then there is no problem and you get BUT (!) if the expr is TRUE then the document is parsed again (don't ask why) and now comes the clue. IF the expr on the second run returns the same result as on the first run, you will get It seems not to be a problem with the rand, it seems more to be a problem when the expr is somehow different in the two runs.
