Improve the functionality of the text box to only allow the entry of the datatype that is associated to the text box. For instance, when a textbox is associated to a integer the textbox would only allow numeric entry into the input.
I can't believe something as basic as this is not available in Mendix - surely more people out there are frustrated with this? This is a standard feature with OutSystems, in fact, you can choose the data type of the Input Widget and it applies input rules to the UI.
When can we expect an improvement? (it has been 3 years since raised)
Also, handle the alignment according to the data type.
