Web Dialog bug?

[Brett McAllister]

Hi there

Currently I am creating some web dialogs and having some real issues with stability.
For no reason at all the dialog will just shut and what ever I have been working on will be lost.
Have any of you guys had this issue or is it just me?
Any help would be appreciated. I am using Sketchup 7
Cheers

Brett

One have to be careful especially when using a Tool and a Webdialog (and Observers).
I think you crash SU because your tool closes a WebDialog already closed or something similar. It can also be caused by creating several instances of a same WebDialog without closing former.

In a thread called Tool <> WebDialog <> Observers relationship I have started to build a 'proper' way of creating a Tool, WebDialog and an Observer. It is far from perfect. I am still learning how to make it error-proof.

Brett,

It sounds like Ruby is garbage collecting the dialog - I've had this happen. If you are using a local variable to reference the dialog and the variable goes out of scope, it will be GC'd.

# This dlg variable will get GC'd sooner or later and the
# dialog may go away.
def create_dialog
    dlg = WebDialog.new(...)
    dlg.show
end

One common solution is to use a module to create a namespace (a scope,) and use a class variable to reference the dialog.

Thanks for the replies.
The only ruby code I am using is just to load the dialog to test it so there is no namespacing etc.
Sounds like that will solve the problem,so I will keep that in mind as I get further along.

Failure to include two parameters in the code block of an action callback is a crime punishable by BugSplat.
