[wtp-dev] ComponentCore.createComponent(IProject)

["Ted Bashor" <tbashor@xxxxxxx>]

My understanding is that during project import (and possibly during startup), some project resources may not be available even though they exist on the machine’s file system.

 

We suspect that this may be causing an early call to

ComponentCore.createComponent()

which calls into

ComponentImplManager.createComponent()

 

      public IVirtualComponent createComponent(IProject project) {

            try {

                  IComponentImplFactory factory = findFactoryForProject(project);

                  if(null != factory){

                        return factory.createComponent(project);

                  }

            } catch (Exception e) {

                  // Just return a default component

            }

            if (!ModuleCoreNature.isFlexibleProject(project)){

                  return null;

            }

            return new VirtualComponent(project, new Path("/")); //$NON-NLS-1$

      }

 

to swallow a null factory or exception and return a “default VirtualComponent”, for which any web project WebContent directory mappings will be invalid, etc.

 

My question is, what would be a preferred way to detect this situation?

 

Calling IVirtualComponent.exists() doesn’t seem to be what we want, since it just checks that the project exists and has the module core nature.  I’d hate to wrap my call to ComponentCore.createComponent() with a check for whether either “.settings/org.eclipse.wst.common.component” or “.settings/.component” (and deployment descriptors?) are synchronized, but is there no other way?

 

Seems like createComponent (or a variant) should be returning null or propagating the exception, but I assume this isn’t an option for 1.5.x…

 

Thanks, Ted
