Category Archives: ICN Known issues

This category summarizes all issues I found on the IBM Content Navigator, and when I can, gives a workaround or a fix.

Changing an ICN file type filter name

Have you ever changed a File Type filter name in ICN? Well don’t, that’s not pretty. All the associations of Entry Templates you’ve done on folders will just stop working, or at least stop offering the user the right Entry Template for the document’s MIME Type. In the configuration it looks like this:

icn_filetype_filter_broken

Explanation is simple. In ICN, apparently there is no ID for File Type filter, or more specifically the name is the ID, which means where you are doing an Entry Template association in ICN, an JSON object is stored as a folder preferences annotation, persisting the File Type filter name directly. Of course if you change the File Type filter name, they won’t look for all folder preferences annotations and change the File Type filter name in it, which means they will all be broken.

Entry Templates inheritance not working

I had to refactor this article because it didn’t make as much sense as now in my mind when I first wrote it. This is now split in two with a main post being this one. Hopefully it will be more understandable for everyone!

Symptom

You have associated an entry template to a folder, or the ObjectStore itself. You tried to add a document into a subfolders, but your entry template never appears in the selection list of entry templates. If you go into the properties of the subfolders to see if the entry templates are correctly inherited, you can see either an empty list, or it says there are inherited entry templates but the File Types are really strange and error is displayed. Here are what you see and what you were expecting to see.

What you see of one subfolder of the one you applied entry template on

What you see on a subfolder of the folder you saw the above screen shot

Here is a video describing the problem, so you can understand better.

Custom MIME Type not working

Symptom

You want to use a new MIME Type in IBM Content Navigator, for example application/dita+xml. You did add a File Type filter under the settings panel from the administrator (DITA files using the dita MIME Type you just created).

ICN_customMIMEType

Then you used this file type filter to filter an entry template associated on a folder.

ICN_customMIMEType2

However the entry template is never displayed when adding a document. Instead you only see entry templates for Any type of file, or no entry template at all if you have none without filter.

ICN_customMIMEType3

Here we were expecting our entry template associated to the DITA file type filter

You’ve tried adding a MIME Type mapping to inform ICN in WebSphere virtual host, ICN’s web.xml and modify CE’s mimetypes.properties but nothing worked (well if you didn’t try these I can tell you it doesn’t).
