NXJ Designer

What does "no entry point specified" mean?

NXJ needs to know what form(s) should be used as entry points - i.e. possible starting places for your application. If no entry points have been defined, you will see this message when doing a Make or Run on your project. To set up an entry point, right-click on a form in the "Project" tab and select the "Add Entry Point" option. You will also be given the option of adding this entry point to the Control Center menus.

I get a "The Control Center login is invalid. Do you want to try again?" error when trying to deploy/run. What does this mean?

If you have configured your Control Center to require users to log in before being able to do administrative tasks, the Design Center will need to log into the Control Center when deploying. Thus, the Design Center will need to know the username and password to use when logging in.

You can specify the username/password combination to use in the "Control Center" tab of the Design Center Options dialog ("Edit"->"Options..."). By default, the administrator username and password for the Control Center is "admin/admin".

What does the "Conditional" check box mean in the form properties?

If a form is marked "Conditional", NXJ will check for a condition to be true before displaying the form name in the form chooser. In this way you can determine the list of forms that will be displayed at any given time. See How can I set up conditional next forms? for more details.

How can I change the value of a label at runtime?

If you want to be able to change the value of a label at runtime, use a dynamic text field instead of a label. A dynamic text field can be assigned an expression that will supply the value for the label. For example if you wanted the field to represent the text stored in a variable named 'info' then your expression property would be set to '=info'. Whenever the dynamic text field is displayed, the expression will be evaluated to determine the value. See How do I get the current date and time in NXJ scripts? for an example.

How can I see the layout of my form without deploying and running my application?

Select "Layout"->"Preview" from the dropdown menus to see a preview of your form in a browser window. Note that this will not show any toolbars or headers/footers that you have assigned..just the form itself.

Why are some object properties in Italics?

Italics shows that the value is different than the default for that object or style. To revert back to the default use the right mouse "Use Default" option on the property.
