Re: [orca-list] I need help

Hi Joanie.

Let me try to explain.
When I press the F11 key eclipse starts my application,  suspends the 
execution in the first line of the main method and put the cursor in 
that line.
At that moment orca receives an event of object:text-caret and the 
function _presentTextAtNewCaretPosition is executed.

Inside this function I have the following sequence of statements:
            obj = otherObj or event.source
            [line, caretOffset, startOffset] = self.getTextLineAtCaret(obj)
            print "obj = ", line, caretOffset, startOffset
            if self._lastTextCaretMoved:
                [line, caretOffset, startOffset] = 
self.getTextLineAtCaret(self._lastTextCaretMoved)
                print "self._lastTextCaretMoved = ", line, caretOffset, 
startOffset

            self.sayLine(obj)
            self._lastTextCaretMoved = obj

These statements are executed and the terminal where I'm running orca 
appears the following text:
        boolean restart = true;

The text in the console is produced by the execution of the first print 
statement. The second print statement is not executed because the 
variable self._lastTextCaretMoved was initialized in the __init__ to None.

The last two statements are executed and the variable 
self._lastTextCaretMoved stores the variable obj.
obj and self._lastTextCaretMoved points to the same place, "        
boolean restart = true;".

Now I press the F6 key.
Eclipse executes the first line of the main method,  suspends the 
execution and put the cursor in the second line of the main method.

Again orca receives an event of object:text-caret and the function 
_presentTextAtNewCaretPosition is executed.
The two prints statements present in the function 
_presentTextAtNewCaretPosition are executed and the following appears in 
the terminal:
    System.out.println("line 1");
    System.out.println("line 1");

I think I should see the following:
    System.out.println("line 1");
        boolean restart = true;

do not know if I could explain clearly because my English is not very good.
Thank you for your great help.
