Hi all,

atm I am fighting with really annoying problem and maybe you guys have an idea 
how to solve that.
So first let me explain what the problem is.

We have created a DSL in which we describe changes to a “schema”. Small amounts 
of code lines may result in “heavy” operations in our model which replicates 
the described changes into the schema.  When opening a file with the generated 
xtexteditor the whole UI freezes cause of the loading times (normally loading 
takes less than a second, but sometimes it takes 5sec +).
This is not a problem of xtext. I am totally aware of that… I just want to 
inform the user about the heavyweight operation and not block him with a 
non-responding UI.

To address this issue my idea was to separate the loading of the resource and 
the creation of the UI. Long story short I loaded my resource in a Job and 
wanted to pass the result to the editor.
And here I got stuck. Sure I can create my own editorinput but this seems to be 
a bit to “much” effort.

Did anyone run into a similar issue and maybe give me a hint how to solve the 
issue correctly?

Kind regards

Michael
