Supress composite default constructor warning

[art]

Hi there,

Is there anyway to suppress the "Composite ... has no default constructor, so it can not be used with GWT Designer." warning?

I can't find anything in the preferences.

It's very annoying that all classes (without the no arg constructor) that have been created outsite GWT Designer are marked with warnings.

Greetings,

Any Composite in a GWT Designer project that is missing the default constructor will be flagged with a warning since there is a presumption that you actually intend to use it in your UI design at some point.

To suppress the warning:

1) Put the Composite in a non-GWT Designer project

2) Add the missing constructor

3) If you are using GWT Designer v3.0.1, you can turn off the Designer > GWT > Check for Composite default constructor preference.

GWT Designer does not care about Composites in non-GWT Designer projects.

That warning is an important hint that in order to be used as a valid custom widget, the Composite needs to define a default constructor.

Rules for using custom widgets are in the GWT Designer FAQ.

Thanks for the reply Eric.

This was the kind of preference I was looking for. I think it's a big plus that v3.01 has this option now.

I'm glad you like it. Just be careful as any Composite that you intend to place into the GWT Designer design view must have a default constructor.
