https://community.qlik.com/t5/QlikView/variable-dependencies-OnChange-triggers-and-infinite-loops/m-p/431411#M160836 <HTML><HEAD></HEAD><BODY><P>Is it possible to create an infinte looping situation by having something similar to the following:</P><P></P><P>Define variable vA = somefunc(vB)</P><P>Define variable vB = somefunc(vC)</P><P>Define an input control that uses vC.&nbsp;&nbsp;&nbsp; At this point, selecting a value for vC should cause vB and vA to change, right?</P><P></P><P>Now define a Document trigger such that if vA changes, set vC = vA.</P><P></P><P>1) Will changing the value of vC now trigger an infinite loop? </P><P></P><P>2) Does the internal "variable onChange trigger" logic actually compare a new value against a current value to determine if there has actually been a change of value or does <EM>any</EM> setting of the variable cause the onChange trigger action(s) to execute? </P><P></P><P>Thanks,</P><P>Steve</P></BODY></HTML> Thu, 17 Jan 2013 13:42:30 GMT
