[mylyn-integrators] Refresh available options for offline task

[Bartek <bimcio@xxxxxxxxx>]

Hi,

I'm writing connector for our in house ALM system and got problems with 
offline tasks.
Some fields in our tasks are edited with drop-downs, thus when 
initializing task in getTaskData(...)  I add information about available 
options to task's metadata, basing on metadata retrieved from our system:

TaskAttribute attr = new TaskAttribute(task.getRoot(), almFieldName);
....
attr.clearOptions();
...
for (ALMField field : almFields) {
   attr.putOption(field.getId(), field.getName());
}

It works fine until metadata in our system is changed, e.g. new possible 
options added to a dictionary. Then, new tasks in mylyn are created fine 
(list of available options contains latest changes).  But when I edit 
tasks created earlier (and saved to offline storage) then list of 
available options in drop downs is not up to date.
I found that those options are saved to offline file, e.g.:

<Attribute id="Status">
<values>
<value>2355</value>
</values>
<options>
<option>
<key>2355</key>
<value>New</value>
</option>
<option>
<key>2356</key>
<value>In Progress</value>
</option>
<option>
<key>2357</key>
<value>Solved</value>
</option>
</options>
<MetaData>...</MetaData>
<Attributes />
</Attribute>

Is there any method I can inject my code to be executed when task is 
edited from offline file? I would add piece of code to update available 
options in this loaded task.

greetings
Bartek
