Question

Expression for a list > a certain number

0

I somehow don’t get why writing expressions is so difficult. I retrieve a list in a microflow through an aggregate list activity which returns an integer. When I want to compare the list size like this: $myEntriesList >= 3 through an expression in a decision node in the microflow, Mendix throws me an error. What is the correct syntax to formulate such an easy check? Thanks.

Hi Philipp,

After retrieving the list, use aggregate list, In decision activity use the output of aggregate list activity (Eg., $count>=3). If the problem exists, please post screenshot here.

Hi Philipp,

By the looks of it you're comparing the List in your decision to 3 instead of the Aggregated Integer that you obtained by using the Aggregrate List > Count.
