Visual task board card links do not honor display override which can show blank if number column has no value. - Known Error

Visual task board card links do not honor display override which can show blank if number column has no value. Description If you have a table that is extended from task and you use a different field for your unique value on that table and do not populate the number field in task, the visual task board for that tables show a blank href link to the task record. It just shows white space.

Steps to Reproduce

1) Create a new table which is extended from task 2) Add a custom field to the new table to hold a the unique numbering value 3) Create a dictionary override against the task.number field for the new table to override the display value 4) Set the display column to true on the new field you added in step 2 5) Add some records to your table and make sure task.number is not populated with a value and that your new field does have a unique value 6) Create a visual task board against your table Note that the card link is just white space. It is on the page and clickable but because number has no value it does not render.

Workaround Use a before insert/update business rule on the custom table to copy the value of the custom field you are using for numbering into number field if the number field value does not already match the custom number field value. For example, if your custom field was u_number, the business rule script might look like:

if (!current.u_number.nil() && (current.number.nil() || current.number != current.u_number)) {

current.number = current.u_number

}
