[1.1.0] Mac: App.getClipboard(): java.io.IOException: system clipboard data unavailable

Asked by Jonathan

I am using Sikui 1.1.0 Build:2015-06-24_01:00nightly on a MAC OS X 10.7.5.

My application clicks in a text region, selects it and copies it to the clipboard before processing this text further. My application can run and do this hundreds of times successfully and then suddenly I get the following error:-

[log] CLICK on L(718,1044)@S(0)[0,0 1920x1200]

[log] ( ? ) TYPE "a"

[log] ( ? ) TYPE "c"

Looking through past faults there seems to be some references to this. Is there still a known fault? Is there a work around? What is happening? Can some other resource be grabbing the clipboard? Perhaps if I knew what I could disable it.

All help/suggestions welcome

Jonathan.

according to some bug posts in the net, this seems to be a special Mac/Java problem, where there is no solution.
Nothing special with SikuliX.

The recommendation is, to catch the exception and try again or ignore.

so you might do this:

isUnavailable = "#UNAVAILABLE#"
try:
    text = App.getClipboard()
catch:
    text = isUnavailable
if text == isUnavailable:
    # do corrective actions

Thanks for your prompt reply. As you have suggested I have implemented an alternative strategy when this situation arises.
