I have put together, from another forum post, a UNZIP custom action block and have successfully uploaded and deployed, however when customizing the links on the action block, the input and output parameters defined in the Java do not appear.
With the custom action block in a transaction that is executed interactively the following error is observed. Without the custom action in the transaction, no error is generated.
- Transaction Complete.
- Error executing transaction: Could not service request, Unable to load transaction [TMP72152460-151a-11e6-999b-d2a40a340178.trx]
And the following appears in the system log
<?xml version="1.0" encoding="UTF-8"?><Rowsets DateCreated="2016-05-08T12:43:20" EndDate="2016-05-08T12:43:20" StartDate="2016-05-08T12:43:20" Version="15.0 SP2 Patch 4 (Nov 7, 2014)"><FatalError>Could not service request, Unable to load transaction [TMP72152460-151a-11e6-999b-d2a40a340178.trx]</FatalError></Rowsets>

Reviewing my code, taken from another post, can you identify what is missing that would cause this problem. Regards, Hank
