Hi All

When it comes to input validation in EMF Forms I quickly find the email string example in the net. What I'm looking for is an example on how and where to compare two integer attributes. For example, a user sets the input into the forms of the viewmodel and I want to check whether the integer of attribute attMin smaller than the integer of attribute attMax

attMin < attMax

Can anyone help here ?

Many thanks

Olaf

Hi Olaf,

you would need a custom validation for this.
You can find an example on how to create one here: https://eclipsesource.com/blogs/tutorials/tutorialshow-to-customize-the-emf-client-platform/#validation

Best,
Eugen

Hi Eugen

Good support. Many thanks.

This was exactly what I was looking for. Interestingly, the default code snippets provided by Eclipse did not work properly and did not change the EMF Forms to the error color (RED). But the example given with this link was working better.

Thanks a lot again


Olaf
