Dear, I have a stepper that has a disabled property, which is set to false when the formgroup is valid.
But from the moment one of the formgroups is valid, the indicator disappear
<ejs-stepper #stepper (stepChanged)="onStepChange($event)">
<e-steps>
<e-step
#step1
[label]="'NewProject.Identification.Label' | translate"
[text]="'1'"
></e-step>
<e-step
#step2
[label]="'NewProject.Classification.Label' | translate"
[text]="'2'"
[disabled]="projectIdentificationFg.invalid"
></e-step>
<e-step
#step3
[label]="'NewProject.Timing.Label' | translate"
[text]="'3'"
[disabled]="projectIdentificationFg.invalid || projectClassificationFg.invalid"
></e-step>
</e-steps>
</ejs-stepper>
