Getting a cast invalid error while trying to conditionally display a standard icon indicator in a paging grid

vspravin over 7 years ago

Hi,

I am trying to conditionally display a standard icon indicator in a 2 column paging grid by calling a!iconIndicator() inside a!documentImage() to display this icon in a grid image column. However, i get the following error instead:

Interface Definition: Expression evaluation error at function a!documentImage [line 45]: Could not cast from Rule or Function Reference to Document. Details: CastInvalidCould not cast from Rule or Function Reference to Document. Details: CastInvalid

Attached corresponding SAIL code that throws this error.

Any help to fix this issue is highly appreciated

I am pretty sure the problem is here:
apply(
a!documentImage(
document: if(
_,a!iconIndicator(
"PROGRESS_RUNNING"
),
a!iconIndicator(
"PROGRESS_PAUSED"
)
)
),
index(
local!dataForCurrentPage,
"isActive",
null
)
)

You can't loop over an arbitrary expression using apply(); it either needs to be a function or rule.

Could you try putting your a!documentImage expression in a rule that takes in isActive as a parameter?
