I found something => it's seems that it trigger the OnValidSubmit event from the standard blazor compo (present in First modal). I don't know why. I will go deeper.
Ok my bad : it seems that trigger the "OnValidSubmit" event on each button if you don't specify the type (type="button"). The default type is "submit" for each button in the tag. You can close the issue. SRY.
When I "Show" the second modal from the first one it closes the first one.
It's like the second modal "Show" call ModalService.Show("TEST"), params) forces a close on the first modal and I don't know why.
I pass data from the main page to the first modal and from the sfirst modal to the 2nd modal I don't know if it can have an effect.
Expected behavior First modal needs to remain open.
Hosting Model (is this issue happening with a certain hosting model?):
Additional context Pass data and waiting for a result from both modals (1st and second)
