AnAction from Swing component that invokes a Git4Idea call

Please clarify what is the ActionID you're calling here, ideally also snippet showing invocation.

My action doesn't have an action ID as it's added to a com.intellij.notification.Notification (in the case where it's working).

In the case where it isn't working, I execute it as:

openPRList.addMouseListener(new MouseAdapter()
                            {
                              @Override
                              public void mouseClicked(MouseEvent e)
                              {
                                if (e.getClickCount() == 2)
                                {
                                  String selectedPullRequest = openPrModel.getElementAt(openPRList.locationToIndex(e.getPoint()));
                                  if (selectedPullRequest != null)
                                  {
                                    for (PullRequest pullRequest : pullRequestsForProject)
                                    {
                                      if (pullRequest.getTitle().equals(selectedPullRequest))
                                      {
                                        JList checkBox = (JList) e.getSource();
                                        ApplicationManager.getApplication().invokeLater(() -> {
                                          DataContext dataContext = ActionToolbar.getDataContextFor(checkBox);
                                          SwitchToPRBranchAction action = new SwitchToPRBranchAction(pullRequest);
                                          ActionUtil.invokeAction(action, dataContext, "BitbucketPR", null, null);
                                        });

Please try invoking in non-EDT way using com.intellij.openapi.progress.ProgressManager

Invoking per:

ProgressManager.getInstance().executeNonCancelableSection(() -> {
  DataContext dataContext = ActionToolbar.getDataContextFor(checkBox);
  SwitchToPRBranchAction action = new SwitchToPRBranchAction(pullRequest);
  ActionUtil.invokeAction(action, dataContext, "BitbucketPR", null, null);
});

Still produces

It doesn't seem to stop the flow though, not sure what's happening under the hood but my subsequent lines are executed - but it does produce the error log saying that my plugin produced an exception.

The subsequent lines are:

GitFetchSupport.fetchSupport(project).fetch(gitRepository, gitRepository.getRemotes().iterator().next()); // produces the assertion exception

GitBrancher.getInstance(project).checkout(targetBranch, false, Collections.singletonList(gitRepository), () -> {

executeNonCancelableSection() runs on invoking thread and thus is not working, please try runProcessWithProgressSynchronously() or background Task

I may need a different way to execute the action then? Executing it as I currently am produces this:

Access is allowed from event dispatch thread with IW lock only.

Which is from the first line of this block:

DataContext dataContext = ActionToolbar.getDataContextFor(checkBox);
SwitchToPRBranchAction action = new SwitchToPRBranchAction(pullRequest);
ActionUtil.invokeAction(action, dataContext, "BitbucketPR", null, null);

ActionToolbar.getDataContextFor(checkBox) must be executed in EDT

Hey - sorry, yes, was being dumb :)

I ended up having to execute the action in the EDT, and moved the runProcessWithProgressSynchronously deeper into the action itself, and all seems good now, thanks.
