Description David Simonek 2002-11-04 14:36:34 UTC

WizardDescriptor.Panel implementations
org\netbeans\modules\xml\core\wizard\AbstractPanel.java
org\netbeans\modules\xml\tools\generator\SAXGeneratorAbstractPanel.java

provide itself as the result of getComponent().
This hurts performance and can cause a clash when
Component.isValid() is overridden.
Please use a separate component class, see details
at
http://performance.netbeans.org/howto/dialogs/wizard-panels.html.

Easy to fix, P2 justification - performance is top
priority.

I'll fix it soon...

Comment 2 _ pkuzel 2002-11-05 17:48:39 UTC

core/wizard used in New from template isValid() clash fixed. It was
not P9E problem because it uses custom WizardIterator that lazy
initializes wizard panels.

Comment 3 David Simonek 2002-11-05 17:59:13 UTC

Agreed, but only halfway. Still it's better to create expensive UI
panel in getComponent, so that system can decide when it's right time
to do it - see detailed description section in howto.
