"Error acessing (sic) bean" error on some clients

Classic Servoy
1

Hi,

First of all let me say that i’m not that experienced in Servoy development, so please bear with me.
For our client we’ve taken on a Servoy-project on which i’ve been working for the past few months adding functionality to it, partly in form of a javabean.
During development of the bean i had some minor issues getting servoy to recognize the bean, but nothing major.

The problem I’ve got on my hands now is that the bean does not work for some of the client’s computers. I’ve made a simple testbean (the one with the JSlider made in the tutorial on Servoybeans by Patrick Talbot) which again works on my devmachine and most other clients, but does not on some.
it seems to me that Servoy can’t find the bean, stores it as undefined and then tries to call a method on it, resulting in a TypeError.

The whole company in which the app is used works on macs (i myself work on winXP), and on all those except 2 the bean works without any problems. We’ve also got the problem on a macbook at the office (which is a last gen MBP with Snow Leopard).

We’re (still) on Servoy 4.1.3 but are going to begin upgrading to 5.x once this problem is solved as it’s quite urgent. (could this be solved by upgrading?)

i can’t find any errors in the logs (or i’m not looking in the right place) and google doesn’t give me anything either. I’ve self signed the jars, but that didn’t solve the problem (maybe I didn’t do it correctly?)

Does anyone have any ideas what might be wrong?

Thanks,

It looks like your bean is not loaded.
I can hardly imagine that there is really no info in your console, log file (server) or client log?

Since in your case the error is happening on the client-side, an exception must have been throwned on the client-side…

To see what’s happening in there, start the app with the java console displayed, you can do that by going to the Java preferences, in the advanced tab, under Java console, check “Show console”, then you will see what’s going on in your bean.

Hope this helps,
