Define a Regular expression in one place and use it

37

In the modeler, we can check regular expression as follows:
- Entity validation Rule:
  we can only use regular expression material as regular expression.

- input widget validation expression: 
  we can only use string value as regular expression. 
  e.g)
   isMatch($value,'^[0-9]+')
  
- Rule or microflow:
  we can use string value, Constant value and Enumeration's caption value. but we cannot use regular expression material's value.
  e.g)
   isMatch($value, '^[0-9]+'),
   isMatch($value, @sample.regxConstValue)
   isMatch($value, getCaption(sample.EnumerationRegx.value))
   we cannot use isMatch($value, regular expression material's value).


I would like to define a regular expression in one place and use it.
Idea as follows:
- Would it be possible that mendix allow to use regular expression material's value in all validation 
scene(e.g. Entity validation rule , input widget validation expression , Rule, microflow) ?
- Would it be possible that mendix allow to use Enumeration's caption value in all validation scene?

Isn't this covered by Constants now? As you can make them available in client too.

I read somewhere Mendix wants to focus on the core. This should certainly qualify.

Now, I don’t use Regex at all; just re-using Rule, which does the RegEx

Submitted two years ago. Still not implemented?

Totally agree.

You should define the regexes in one place only: the Regex materials.

You should be able to use them anywhere.
