Some time ago, we found that the BigDecimals was not considered in the supported operations by Expression Language. I also opened an issue: https://jira.springsource.org/browse/SPR-8716
If you are interested, we'd like to share our enhancement.
The updated operators are:
Added BigDecimal capabilities to SpEl numeric operators
This should cover the issue
Giovanni, could you please indicate that you've signed the CLA per the contributor guidelines?
Also please check that there are no conflicts with some recent changes that were made to OpPlus. You can rebase against the latest SpringSource/master and do a force push to update this branch. Ideally, you should actually submit the pull request from a branch named SPR-8716, instead of your master branch. This is also covered in the guidelines.
Update code to upstream / master
It seems that I made a mess!
Please, forgive me: I'm not used to Git, and I'm trying to repare...
No problem. Git takes a little time to get used to, but it's worth it! Feel free to simply create a new pull request with the cleaned-up commits.
Following your suggestion, i'm closing this pull request, to create a new with cleaned-up commits.
