If Empty Hash is used to show alternative message in the case of unparsed hash variable.
Format
#ifEmpty.$$[OriginalHash]$$.[Message to Show When Hash Fails to Parse]#
For example, on the following hash
#date.MMM dd, yyyy[{form.table.field}|yyyy-MM-dd]#
If the form hash fails to return a value, then the result would stay as it is because it has failed to parse successfully.
#date.MMM dd, yyyy[{form.table.field}|yyyy-MM-dd]#
By using this hash variable, we are encapsulating the original hash in this hash variable by using the following code. Replace # with $$ in the orignal expression for proper parsing of the orginal hash.
#ifEmpty.$$date.MMM dd, yyyy[{form.table.field}|yyyy-MM-dd]$$.N.A.#
If the original hash fails to parse, then the result would be as following.
