    * If the change is a MetaChange, create a TextStyleChange (interval - the whole text, style : HotStyleDef.empty()). update the model with it. The result is that the caret and selection are not changed. If the current caret index is in the text, it will stay there. If not, it will automatically be displayed in the text end.
  * Online collaboration:
-  * Extend the property in ResourceTextModel. Keep internally a list of ResourceRevisions. All the incoming revisions should be added subsequently to that list. In the case when the access to the text resource is a DelegatingServerAccess one, write a new logic for the property - when a change occurs:
-   * Find the last resource revision id in the resource that is contained in our list. 
+  * Extend the property in ResourceTextModel. Keep internally the last processed resourceRevision. All the incoming revisions should be put on the place of the last one. Together with them, make a hash map, mapping revision ids to imm texts. In the case when the access to the text resource is a DelegatingServerAccess one, write a new logic for the property - when a change occurs:
+   * Find the last resource revision id which is common for the last revision history and the current history.
+   * In the last revision history, create a reverse change for every change after the found id (if change C is applied to text A and the result is text B, the reverse is the change that applied to text B would create text A).
+   * In the current revision history, just get all the text changes after the found revision id.
+   * Get the reversed list of the first changes, then add the list of the second changes. Update the view model with all of them.
