Directory Browser field

I'm currently putting the latest finishing touches on a plugin I'm
going to release shortly. Mainly the stuff is gui related work.

In the I need a directory selection in a dialog. This dialog is
actually constructed with the forms editor. Right now it contains a
JTextField for that purpose. While browsing throught the openapi I
found and tried the following -

GuiUtils.constructDirectoryBrowserField( view.uiString, "Local
Repository Path" );

unfortunately it doesn't work as expected, the text field vanishes (not
displayed, not tab'able) etc. Is there something that I'm missing?

any ideas? thanks, oliver

PS: I'm currently testing against 2253 on Mac OS X
