Add ability to lazy load a value backend

[LordKrabo]

@niteshthali08 I am adding these to Sprint 75.

• [x] Create branch 'importValue' for every bundle that needs one
• [x] Add ImportValue to Geppetto ecore (in org.geppetto.model)

• [x] Add backend functionality to resolve a ImportValue

[niteshthali08]

@tarelli : Could you please list set of actions on the UI which will invoke resolveImportType functionality ?

[tarelli]

@niteshthali08 at the moment it's just from the Javascript API, when you have an ImportType you can call resolve on it, see this

[niteshthali08]

@tarelli : What would be the value of "String path" received by function "resolveImportValue(String path)" would look like ?

[tarelli]

@niteshthali08 the path of the variable or type that the value is attached to (e.g. nwbSample.response currently or a more complex one given the new design nwbSample.sweep100.stimulus.recording)

Thanks @tarelli, I need your help in understanding few things. Can we have a small meeting on Thursday or Friday ?

Hey Nitesh, I'm out of commission for the rest of the week but @gidili can answer those questions as I've caught him up with what you are doing.

@gidili: are you available for some time during this week for a small meeting ?

[gidili]

@niteshthali08 yes! I'll send you an email to schedule

Add this to sprint 76 @niteshthali08 @tarelli @gidili ?

@tarelli: I have committed the code. So I wanted to write a jUnit test case to call the functions on backend so that I can test them as they are executed. I just copy pasted code from one of the existing test case DataSourcesGeppettoManagerTest.java into ImportValueTest. I have created test2 folder inside resources with NWB stuff. Could you please help me in getting this work ? I want this test case to call the method resolveImportValue(path).

@niteshthali08 I haven't found your test anywhere but I committed some code to show you some more pointers

[niteshthali08]

@tarelli : Sorry for that there was a merge conflict while pushing which got neglected by me.

[niteshthali08]

@tarelli : I have modified nwbModelInterpreter to return display text according to the proposed design for lazy loading. It would be great if we can have one small meeting at the earliest in coming week to get some pointers on implementing frontend.

I tried to write a test case to test out the resolveImportValue functionality. I created "ImportValueTest.java" but it is throwing an exception at the line given below. "appContext" is returned as null. public static Object getNewServiceInstance(String discoveryId) throws GeppettoInitializationException { ApplicationContext appContext = ApplicationListenerBean.getApplicationContext(discoveryId); ... }
