Multiple Multishuffles

**dino2dy** · November 8th, 2010, 09:29 AM

Hello everyone I use Jdeveloper 11g R2 and have 3 multishuttles on my jsp that are all supposed to refresh when navigation buttons are pressed.

This means all the multishuttle code should be in a single backing bean, so the navigation button could call the refresh method from that bean, which would refresh all three.

This is the code I have

Unfortunately this comes with problems when commiting the values (the refresh works), as the values are not stored in the database, and I get a commit value problem output message. If I put them in separate java classes it works, and will commit for all three, but the refresh button only works for one multishuttle (the one that has the method it uses for action).

I am a beginner in Java so really any help would be greatly appreciated.
