Again - don't use if for a construct dealing with different values of
the same field, since this can be done with CASE more easily and in a
readable way. Didn't measure performance, but I guess it should be
faster as well, since any other option will be ignored completely
without having to handle at least the if clause.
Just insert a CASE element on the level before the part, that should be
changed depending on the layout.
i.e.
itemRendering {
wrap.cObject = CASE
wrap.cObject {
key.field = layout
# any other value of the layout field
default = COA
default {
10 = LOAD_REGISTER
10 {
myRegister.dataWrap = {field:whatever} some value
}
}
# if layout 1 is selected
1 < .default
1.10.myRegister.dataWrap = {field:whatever} another value
# if layout n is selected
n < .default
n.10.myRegister.dataWrap = {field:whatever} another value
}
}
You can even combine fields to get the key for CASE:
key.dataWrap = {field:backend_layout}X{field:layout}
default = TEXT
default.value = Default Text
1X1 = TEXT
1X1.value = Value for backend layout 1 and layout 1
1X2 = TEXT
1X2.value = Value for backend layout 1 and layout 2
2X1 = TEXT
2X1.value = Value for backend layout 2 and layout 1
2X2 = TEXT
2X2.value = Value for backend layout 2 and layout 2
Of course this can even be enhanced with if, but IMHO it should not be
used to evaluate an unknown list of variable options.
