I followed this tutorial to add a FilenameComponent and TextEditor to my audio plugin, but when I run it, I get:
Exception thrown: read access violation. this was 0x20.
I found this error occurs when I have the line:
fileComp->setBounds (10, 10, getWidth() - 20, 20);
or the line:
textContent->setBounds (10, 40, getWidth() - 20, getHeight() - 50);
in the resized method of the AudioProcessorEditor derived class. These lines are found in the demo header file.
I searched and I cannot find out why. I suppose, what is different to consider when adding one of these components to an audio plugin vs a standalone application? I tried the demo out and it worked fine, so it has to be something with it being an audio plugin.
My stack trace is:

I noticed at the time of the stack trace, the program is unable to read the variables: w, h, pos.x, and pos.y. It says for those variables, <Unable to read memory>.
My resized method looks like this currently:
void FsynthAudioProcessorEditor::resized()
{
// This is generally where you'll want to lay out the positions of any
// subcomponents in your editor..
//midiVolume.setBounds(40, 30, 20, getHeight() - 60);
//fileComp->setBounds(10, 10, getWidth() - 20, 20);
textContent->setBounds(10, 40, getWidth() - 20, getHeight() - 50);
}
I have the lines commented out as I was trying to see what was causing the error.
