Something leads to wrong condition expression evaluation.

Inside content module i have 2 variables which are assigned to id attributes of 2 hierarchical units. I want to hide the grid cell if both units are empty using visibility condition. If i write just one line "return false" in condition expression it works fine(obviously) but even this code always evaluates to true:

def expr = share != null || details != null
println expr
return false

How can that be? The value of expr printed to system output is 'false' but putting <c:out value="${webratio:evaluateCondition('miu41dcexpr291d', null, pageContext)}"/> in jsp returns true. And yes, i've put 'return false' here but even with this it evaluates to true. So the cell is always shown.

Hi,

in order to obtain the desired result, you can try the following solution:

1) Add two Selector Units inside the page containing the Hierarchical Index Units. Each Selector Unit is related to the Entity specified on a Hierarchical Index Unit (e.g. the Entity of the Selector Unit 1 is the same as the Entity specified on the Hierarchical Index Unit 1 at Level 0, and so on).

2) Add two variables: the first one refers to the "Data Size" parameter of the Selector Unit 1, while the second one refers to the "Data Size" parameter of the Selector Unit 2.

3) Add a Condition Expression working on the previous variables ("var1" and "var2" are the name of the variables):

def expr = var1 != 0 || var2 != 0
return expr

4) Select the Grid Cell containing the units and in the Condition tab, set the "Cell Visibility Cond." property to the Condition Expression.

In this way, if both Hierarchical Index Units are empty, the Grid Cell will be hidden.
