Selector in a variable

when I have selector like world&apos…When I stored it in a variable and pass it to selector it is not working but when I directly using…it works. Why and how can I handle this?

try to setup dynamic like described in following link (as it also have the benefit o not losing the validation functionality)

if it needed to do it on variables and + syntax ensure the selector code is not done within UiExplorer edit box, as this is replacing a ’ into the Entitiy `" . We do edit such a selector string in the expression Box (Properties panel from activity)
