Because I simplified the code a bit.

I am actually testing if a control of a component contains a value or not.
And as far as I am aware of, there is no [if control test_value] 
available in IC.

I had something like below in a modified random component:

[loop serach=|
         fi=products
         st=db
[if type=explicit condition="[control brand]"]
         sf=brand
         se=[control brand]
         op=eq
[else]
         ra=yes
[/else]
[/if]
|]
         do something
[/loop]

Everything seemed to work well until we discovered that for
brand=00000159 no proper results were returned.



Best regards,

Ton
