I've deployed XADisk.rar (1.2.2) on my Websphere JCA Resource Adapter list.
Now I'm trying to configure it using the tab "Custom properties". Some properties are easily editable (like the instanceId), but some others are not (like xaDiskHome - which is a quite important one).
Why and how to make these properties editable?
As indicated in the comments by Gas, there is a bug in the WebSphere frontend console, that make any entry on the 2nd or more page of the "Custom properties" page READ ONLY.
Changing the filter value to display "100" entries per page, and playing a bit with the UI, I was able to configure XA Disk fully. Funny bug yea, but it costed me much much time to find the cause...
