Expression evaluates as blank when it is not…
I am using the following expression as a Show_If constraint. The field should only be shown if another field is blank. The expression, =ISBLANK([_THISROW].[StructurePhoto]) returns TRUE when in fact the field [StructurePhoto] is not blank. [_THISROW] is set as an enum filed and [StructurePhoto] is set as an image type field.
I am using a similar expression within another table to determine which field to show the user. Here, the expression returns the correct results. =IF(ISBLANK([StructurePhoto]),[StructureSketch],[StructurePhoto])
I am at a loss as to why one filed the correct results are returned and the other not. Is this a bug?..
