Hi,
We have a RCP Application that is creating a tree in a view. After a
long startup process, we create the tree control and we try to insert some
elements.
In some cases (we are not able to reproduce always), the insert
process throws an SWTError:
org.eclipse.swt.SWTError: Item not added
at org.eclipse.swt.SWT.error(SWT.java:2717)
at org.eclipse.swt.SWT.error(SWT.java:2616)
at org.eclipse.swt.SWT.error(SWT.java:2587)
at org.eclipse.swt.widgets.Widget.error(Widget.java:381)
at org.eclipse.swt.widgets.Tree.createItem(Tree.java:285)
at org.eclipse.swt.widgets.TreeItem.<init>(TreeItem.java:77)
We have checked the source code of the Tree.createItem method:
if (OS.SendMessage (handle, OS.TB_INSERTBUTTON, index, lpButton) == 0) {
error (SWT.ERROR_ITEM_NOT_ADDED);
}
Looking the Windows API, it explains that when it can not insert the
element, the TB_INSERTBUTTON message process return 0. But it doesn't
explain in which conditions it can not insert the element. We have tried to
use the OS.GetLastError() method but always return 0;
Why it can not insert the element? There is a tool, or a API to find the
windows error?
Can somebody help us?
Thank you in advance

It sounds like you are leaking and Windows is running out of resources. Can
you recreate the error after commenting sections of your code? If you don't
create the tree, does the problem go away?
