Required component, Avoid deselect,

[QooScho]

Hello,
In my project there are components like this:

Define Component: My Server
Define Component: My Server\Driver
Define Component: My Server\MySQL Database
Define Component: My Server\Web

I want that If "my Server" is selected the chield "My Server\MySQL Database" is always selected and cannot be deselected by the user.
I tried this:

Get Component My Server Selection State into Variable SELECTED
if Variable SELECTED Equals TRUE
Select Component: My Server\MySQL Database

The problem is that the MySQL is selected but the user can deselect the item if he want.
Is it possible that in the component tree or treeview we can make a dependency to the "next" button, so that the Next button is disabled if the MySQL is not selected?

regards
Hansjoerg

Dear Hansjoerg,

You cannot create that constraint (I have tried before).
What you can do is check the validity of the selection AFTER the user has pressed Next, and then if the selection is invalid display a message box and go back to displaying the previous dialog.

I agree. This actually came up a few weeks ago and we are definitely aware of it.
