Cannot assign a nil to a TJPEGImage

If that message of cannot assign a nil .... was obtained in STAR UML, when you want to export the diagram.

The problem is that you have some error in your diagram.. you can probe that by click in the Model menu, and click in the verify model submenu.

So, the solution for this is modify any error in the annotations, maybe a bad connector or bad association it has missed or a stereotype like < < include> >; or < < extend > >;. and after that you will be able to export the model without any problem.

See all the portlets in the category in liferay

If you are using LIFERAY, for see all the portlets of a category in case that there are a lot, you have to use Internet Explorer.

Both Firefox and Chrome, don't allow the visualization of all, because the size of windows of them are smaller than the list of portlets.

PORTLET SIZE VAADIN LIFERAY

The AbsoluteLayout works with portlets as such as Horizontal and Vertical Layout (Vaadin GUI) do , the only thing that you have to do is to modify the size of it in a fixed way, because the porcentual value doesn't works with portlets.

so:

The correct way to set the size is:
mainLayout.setWidth("500px");
mainLayout.setHeight("400px");

you CAN NOT do this:

AbsoluteLayout mainLayout= new AbsoluteLayout();
mainLayout.setWidth("-1px");
mainLayout.setHeight("-1px");

neither : mainLayout.setWidth("100%");

Ver todos los portlets de una categoría en Liferay

Si estas usando LIFERAY, para poder ver todos los portlets de una categoría en caso de que sean muchos debes usar Internet Explorer.

Firefox y Chrome, no permiten la visualización de todos, porque las ventanas de ambos browsers o exploradores son más pequeñas que la lista.
