Where has the 'select class' button gone?

[jsilva]

Hi, everyone.

I have recently updated from Designer 5.12 running on Eclipse Indigo to 5.14 on Kepler. On the Java service tasks, the "Select class" button has completely disappeared. I've already tried reinstalling the plugin, and that does not solve the issue. Is the button present on the new version? If it is, what else could be causing this?

An image of the problem.

Try resizing the property-window and scrolling right, maybe it's just hidden off-screen?

Hi.

Although it wasn't clear from the picture, I'd already done that. It's not there. What can be happening, here?

[frederikherema1]

Do you see any errors in the "Error log" view in eclipse, when opening the properties for a service-task?

Nothing related to Activiti, unfortunately.

Thanks for reporting this, it's a bug that the select class button is not visible anymore.
We'll look into it and fix it.

Best regards,

[eugenemaya]
