> UI shows N/A for start time and console URL
> We do parallel job submission for forked actions, and each job submission
> needs to update workflow instance.
> To avoid data race, ForkedActionStartXCommand write workflow instance to a
> temporary map.
> {code:title=ForkedActionExecutorContext.java}
> private Map<String, String> contextVariableMap = new HashMap<String,
> String>();
> public ForkedActionExecutorContext(WorkflowJobBean workflow,
> WorkflowActionBean action, boolean isRetry,
> boolean isUserRetry) {
> super(workflow, action, isRetry, isUserRetry);
> }
> public void setVar(String name, String value) {
> if (value != null) {
> contextVariableMap.remove(name);
> }
> else {
> contextVariableMap.put(name, value);
> }
> }
> {code}
> And when forked submission completes, the temporary map is written to the
> workflow instance.
> {code:title=SignalXCommand.java}
> List<Future<ActionExecutorContext>> futures =
> Services.get().get(CallableQueueService.class)
> .invokeAll(tasks);
> for (Future<ActionExecutorContext> result : futures) {
> if (result == null) {
> submitJobByQueuing = true;
> continue;
> }
> ActionExecutorContext context = result.get();
> Map<String, String> contextVariableMap =
> ((ForkedActionExecutorContext) context).getContextMap();
> LOG.debug("contextVariableMap size of action " +
> context.getAction().getId() + " is " + contextVariableMap.size());
> for (String key : contextVariableMap.keySet()) {
> context.setVarToWorkflow(key,
> contextVariableMap.get(key));
> }
> {code}
> The logic for writing to the temporary map is incorrect. It should be
> {code}
> public void setVar(String name, String value) {
> if (value == null) {
> contextVariableMap.remove(name);
> }
> else {
> contextVariableMap.put(name, value);
