Content assistant problem

Question

how to implement content assisatant (ctrl+space) in JavaFx textArea?

Answer 1

Situation has changed - now content assistant is working almost ok, for both editors. CreatePage0 function is the same, the only change in code is:
@Override
protected IEditorPart getEditor(int pageIndex) {
//return super.getEditor(pageIndex);
super.getEditor(pageIndex);
if (composite != null)
Control focus = composite.getDisplay().getFocusControl();
if (focus !=null){
while (focus.getParent() != null && focus.getParent() != composite){
focus = focus.getParent();
if (composite.getChildren()[0].equals(focus)){
if (logicInputActive != true)
logicInputActive = true;
setActiveEditor(logicInputEditor);
activateSite();
}else if (composite.getChildren()[1].equals(focus)){
if (logicInputActive != false)
logicInputActive = false;
setActiveEditor(logicOutputEditor);
activateSite();
StructuredTextEditor o = logicInputActive ? logicInputEditor : logicOutputEditor;
return o;
So i get the element with focus, and whether it's child of logicInputEditor(it "is in" composite.getChildren()[0]) or logicOutputEditor(composite.getChildren()[1]). This part of code works fine(or at least i think so...). Problem is quite weird - if you click on editor TWICE or once + type something(some random letters) - everything is fine(content assistant shows in this editor), if you click only once content assistant shows in last editor in which you clicked twice. So even if getEditor() function returns "correct"(active) editor, for some reason content assistant shows in "wrong" editor. I tried to override getActiveEditor, but it doesn't change anything. Any ideas what can cause this problem and how can i fix that?
