so just as an update... this doesn't appear to behave as expected locally either???

Hi Bob,

I just read this issue: http://issues.umbraco.org/issue/U4-8266

" the problem arises when you load the next tab which uses the same prevalues"

I think this is a new feature in Vorto 1.5. In the change log it says:

• Performance boost for complex properties by using ng-if.

This means the tab is loaded when you open it. I'm running a project on Vorto 1.4 which does't have this feature and I haven't run into this error. So maybe as a workaround you can downgrade to Vorto 1.4.

Ow yeah the file was moved and renamed in 7.4. You could download it from 7.3 and copy it yourself to the correct directory. Did the same in this commit: https://github.com/jbreuer/1-1-multilingual-example/commit/b0b2daadb4aadb01ba49a4c078bb86e9f0b855e4

Having spoken to bob last night, this seems to revolve around 2 issues in core:

1) the checkbox and dropdown list property editors aren't validating passed in pre-values well enough causing issues on tab change (issue here http://issues.umbraco.org/issue/U4-8266)

2) there appears to be a change in 7.4.2 where by a property editors ConvertDbToString function is called multiple times (where it used to be once) causing a similar issue where the stored value gets converted multiple times causing the data to corrupt (issue here http://issues.umbraco.org/issue/U4-8270)

Workarounds for both of these issue have been applied to the nightly found here https://ci.appveyor.com/project/mattbrailsford/umbraco-vorto/build/1.5.2.48/artifacts

is working on a reply...
