SaasNodeChildren should initialize immediately or be asynchronous. In the snapshot initialization takes > 20s.

The snapshots lead to websvc.manager code.

As my latest (275393 and some others) posts, I just can't change the selected file in Projects view. I consider it an 
regression and just can be found at latest build 200910071536. The build 200910070250 doesn't has this regression.
Comment 9 Michel Graciano 2009-10-08 18:53:01 UTC
I decreased the priority since I just removed my indexes and it looks it like is working again.
Comment 10 Michel Graciano 2009-10-10 03:06:09 UTC
BTW, I added new comments at report and looks like the component and subcomponent are incorrect here.
Comment 11 Denis Anisimov 2010-11-01 11:01:58 UTC
The problem is inside websvc.saas.api module.
The stacktrace of the problem starts from SaasNodeChildren class ( websvc.saas.ui)
and its method addNotify() which calls toStateReady( false ) of Saas class .
The last one is overridden by WsdlSaas method.
The parameter value "false" means that call should be performed asynchronously 
which should prevent UI freeze. 
But there is no special logic which handles asynchronous essence .
The problem of the attached nps file is call WsdlUtil.getWsdlData() which asks 
WSDL model . It has parameter for asynchronous call but implementation ignores
this parameter. 
But WsdlSaas.toStateReady() implementation logic is still badly written 
because even WsdlUtil.getWsdlData() implementation is correctly written 
respectively asynchronous call its return value cannot be used for further 
work in the caller thread. All further work should be done after notification 
of finished task.

So actually either
- there is no need in asynchronous call of WsdlUtil.getWsdlData()
and toStateReady() method should put all its code into dedicated thread in case
of asynchronous request
- WsdlUtil.getWsdlData() should be implemented correctly according asynchronous 
parameter value and logic of toStateReady() should be rewritten respectively.

It's too risky to fix this bug for the upcoming release. Should be fixed in the
next release.
