Click on JavaButton sometimes works sometimes not

[bwillems]

I am using QTP 10.0 + addin and try to simulate a java application.

I have built several robots and I observe some robustness problems.

For example the click on a javabutton sometimes works sometimes not.

Do you have experienced also this kind of instability?

I have the same problem with set on javaedit.

Using waitproperty conditions to be sure that the object is available, visible, ... helps but I still have robustness problems.
