Can't figure out how to show error in dedicated field in credit-card-example

[gattiroberto1985]

Hello,

i see that in the credit-card-form example here that an error is stored in the model and an errMsg message is handled in the Update function. But i cannot make the error visible in the UI, nothing appears if i input a wrong character, neither if i print the error explicitly in the View function (if the error is not nil). It seems that the errMsg is never activated.

I can't find any documentation or example about this, is there something wrong in the example?
Thanks in advance!

The validation functions are called by the text models whenever one receives the Update(teaMsg) call, all you have to do is pass it a message and the rest is taken care of. As for the errMsg , that's going to have whatever errors are passed into your program model itself, while the text inputs do error handling in their own Update() methods.
The errors are stored in the individual textinputs, m.inputs[n].Err , and they're set to nil if there's no error.

Hey @hopefulTex,

This is an issue that's being discussed upstream in Bubbles. It would make more sense to continue the discussions and apply improvements over there. Thank you for bringing this to our attention! We haven't forgotten about this issue
