Various issues in staging-extension-2.3.15

[anoissi]

After each synchronization

1. In the "FAQ portlet" interface:

• Display in a random order of categories.
• Display in a random order of questions / answers.

2. As currently we are exporting "Category" class not the category node :

• lost of node properties (exo:createdDate, exo:dateModified,...) => non-conservation of creations dates/ modifications dates of questions,...

3. We got the message "synchronization successfully" independently of synchronisation success .

When exporting many categories

We find export of one only category.

When exporting a parent category

We lose the sub categories of the exported category.

When exporting for non-existent user

We got a log error with a stack trace of the exception.

In the "Staging-extensions portlet" interface
For export or synchronization :

• We can select a parent category and its subCategories in the same export => The parent category overrides the subCategory.
• The subCategories of a space category are displayed in public answers.
• User can synchronize the default category(ROOT-CATEGORY) with replace existing option => delete the root category(Overwrite existing FAQ Category: 'categories' (replace-existing=true) )=> can not synchronize any other category.
