This suggests that, despite your attempts, the ProjectId field was not actually sent to the server.

If you need more help, please show the complete server log for the request (always include this).

I was actually looking at the wrong piece of code.

However, the adjustments that I have made have not worked either.
Below is the relevant code snippets and the error message that I am getting.

I have a Window that gets displayed when the user selects and "Add" Button that I have available.
The Window subscribes to the Project Selected event that was previously described.
The Window also contains a DynamicForm where users are inputting the relevant information and then submitting the form view a "Save" button.

Below is the Save Button Clickhandler....

Code:

newButton.addClickHandler(new ClickHandler() {  
            public void onClick(ClickEvent event) {
            	errorText.hide();
            	if(addUserForm.validate()){
            		if(embD.getValueAsDate().before(debD.getValueAsDate()))
            		{
            			addUserForm.saveData(new DSCallback() {  
							public void execute(DSResponse response,
									Object rawData, DSRequest request) {
								addUserForm.editNewRecord();
							}  
                    	});
            		}
            		else
            		{
            			errorText.setValue("Embark must be before Disembark");
            			errorText.show();
            		}
            	}
            }
        });

Below is the ProjectSelected function that gets called everytime the eventBus fires the respective event...

Code:

public void projectSelected(ProjectSelectedEvent event) {
		
		Record projectRecord = event.getProjectRecord();
		
		final Criterion criteria = new Criterion("ProjectId", OperatorId.EQUALS, projectRecord.getAttribute("ProjectId"));
		addUserForm.setValuesAsCriteria(criteria);
		System.out.println(projectRecord.getAttribute("ProjectId"));
	}

So when the "Save" Button is clicked I get an error message on my Tomcat Server...I have attached the errorMessage to not clutter the forum page.

The Eclipse error message is also attached for further debug info...

Any help would be appreciated.

You seem to be trying to attach Criteria to an "add" operation, that doesn't make sense. Criteria only make sense in update, fetch or remove operations.

Well heres the scenario that I am trying to accomplish...

I have a database table that I am using to maintain a list of people on a project. Therefore the following scenario is possible...

Person 1, Project 1
Person 2, Project 1
Person 3, Project 2
Person 2, Project 2

I am currently using a ListGrid to display the pertinent project information so I am able to do a ListGrid.fetch(projectCriteria) and it correctly fetches the persons that pertain to the particular project in question.

However, I also need a way to add people to a particular project, which is what I am trying to accomplish below, albeit perhaps not in the proper way.

So I created a SelectItem to select the project that I would like to have as the currently "active" project and then use a Form to submit the person to the "active" project.

So I was trying to use the eventBus to allow the Form know which is the currently "active" project so then I can add person the that project.

Hopefully, this elaborates a bit more what I am trying to accomplish and a proper suggestion can be made as to how I can accomplish this task.

Thanks in advance

Well, the suggestion is the same - criteria on an add operation don't make sense. If what you wanted to do was to set the ProjectId on your new record to a specific value, then just set that value - criteria is not involved.

It dawned on me the other day what exactly you meant by your comment.

I finally noticed that DynamicForms have a "setValue" function, which I am now using to solve my problem.

Thank you for the suggestion, I had completely overlooked that function.
