$f_CheckFirstColumn(this) is not working in theme 42 apex 5.

Question

$f_CheckFirstColumn(this) is not working in theme 42 apex 5. it does not tick or untick the check boxes.

Answer 1

I have experienced the same behaviour, this workaround worked for me:
1) In the Page Header Section under Javascript "Function and Global Variable Declaration" I defined this function:
function checkall() {
   $f_CheckAll('', true, $('input[name="fXX"]'))
fXX stands for your checkbox ID in die Select Statement, for example f01 or f30
2) In the column heading of the report column, I call this new function:
<input type="checkbox" onclick="checkall()" />
Hope this also helps you!
