web-client-config-wcm.xml contains a set of widget definitions that can be used to map the combination of XMLschema data type, XForms control, and appearance to a UI control which is used for display.
Appearance names are arbitrary. Any number of controls for the same xforms-type can be configured with different appearance names and then used from any number of forms.
The alfresco.xforms.RichTextEditor control manages a TinyMCEcontrol.
Please note that Alfresco currently supports only TinyMCE version 184.108.40.206. and plugins for that version The latest version of TinyMCE, and plugins for that latest version, will not work properly in Alfresco.
FilePicker configuration (Web Forms only)
Restricting File Picker to content types and/or mime types
The alfresco.xforms.FilePicker takes parameters to restrict which types of content are selectable in the widget, and parameters to filter selectable files by mimetype. The parameter names are
selectable_types which takes as a value a comma separated list of content types as defined in the dictionary
filter_mimetypes which takes as a value a comma separated list of mime type glob patterns.
Here are pre-configured FilePicker examples from web-client-config-wcm.xml, as per Alfresco 2.1:
Restricting File Picker to a configured AVM folder path or configured search (2.2)
New features have been added, to Alfresco 2.2, such that the File Picker can be optionally restricted in two additional ways:
To an AVM folder: To enable this, set the file picker's 'folder_restriction' parameter.
To a configured search: To enable this, set the picker's 'configured_search_name' parameter.
These restriction parameters (mentioned above) must be defined in widget elements in the web-client-config-wcm.xml file for the associated features to take effect.
'File Picker' Folder Restriction
The 'folder_restriction' parameter must be set to a relative AVM folder path (e.g. some/relative/folder/path). This must point to the AVM folder to which you want to restrict the file picker and be relative to the root of the webapp folder (of the web project). Only the contents of the specified folder will be available for selecting in the file picker. If the 'folder restriction' parameter is set to the example relative folder path above, then the absolute path for that AVM folder will be something like '<sandbox-store-id>:/www/avm_webapps/<webapp-id>/some/relative/folder/path' - where '<sandbox-store-id>' is the ID of the sandbox being populated by the file picker and '<webapp-id>' is the current webapp folder (such as 'ROOT' for the default webapp).
To try out this feature, there is a sample widget defined in web-client-config-wcm.xml with appearance 'folder_restricted_file_picker'. This parameter must be uncommented and set to take effect for any XForms schema using a file picker having the 'folder_restricted_file_picker' appearance.
'File Picker' Configured Search Restriction
The 'configured_search_name' parameter must be set to the name of a configured search. The file picker contents will be restricted to the results of this named configured search. The configured search must be stored in the Public Saved Searches folder.
To try out this feature, there is a sample widget defined in web-client-config-wcm.xml with appearance 'search_restricted_file_picker'. This parameter must be uncommented and set to take effect for any XForms schema using a file picker having the 'search_restricted_file_picker' appearance.
