Double click again.....
Hi All,
I had posted a similar query earlier to prevent double click of a form
button.
I could use Shale's <s:token> but i ran into compatibility issues
between RAD6.0.1 and Shale-core.jar1.0.3.
So i had to give it up and try another approach using Synchronizer Token
pattern as in sytuts.
Please help me fine tune it.Please go ahead to provide me any other
elegant approach.
I want to call the method generateSaveToken() from phaseListener.
Is it possible.????

RE: Sanbox: DojoSplitPane error - Some more Info
Posted by "Oellien, F (Frank)" <Fr...@intervet.com>.
Some of the methods in DojoSplitPane and DojoSplitPaneRenderer are
misspelled: get/setSplitOrientanation instead of
get/setSplitOrientation.
Furthermore, the Orientation part in the setProperties funtion of the
DojoContentPaneTag has to be changed from setIntegerProperty to
setStringProperty.
After all these changes, orientation can be set in the DojoSplitPane
component.
Regards
Frank

Subject: Sanbox: DojoSplitPane error
The DojoSplitPane component in the sandbox package seems to have
an error in DojoSplitPaneTag.java.
I receive an error set the setter method vor set
SplitOrientatation is not set in the tag file. Indeed when I look to the
DojoSplitPaneTag.java class the setter method is called setOrientation
instead of setSplitOrientation. This true for sandbox 1.1.4 and 1.1.5
Furthermore I can not set the styleClass attribute for the
layoutContentPane component: Everytime I receive an error that one of
the attributes can be null.

You could just download the token's source code and use only the component
without the other features of shale-core
