Ernie Rael commented on NETBEANS-4696:
--------------------------------------
I went back and looked at removing the dependency from javascript2.knockout to
projectuiapi.base. I had left in
{code:java}
if (!OpenProjects.getDefault().openProjects().isDone()) {
return null;
}
{code}
I took that out (it was before QuerySupport stuff) and it made no difference.
The code is now
{code:java}
KnockoutIndex index = INDEXES.get(project);
if (index == null) {
Collection<FileObject> sourceRoots = QuerySupport.findRoots(project,
null /* all source roots */,
Collections.<String>emptyList(),
Collections.<String>emptyList());
QuerySupport querrySupport = QuerySupport.forRoots(
KnockoutIndexer.Factory.NAME,
KnockoutIndexer.Factory.VERSION,
sourceRoots.toArray(new FileObject[]{}));
index = new KnockoutIndex(querrySupport);
if (sourceRoots.size() > 0) {
INDEXES.put(project, index);
}
}
return index;
{code}
With the early return left out, until the project is open, sourceRoots.size()
is 0 until the open completes. Updating the PR to remove the dependency.
