double dot   ..property  is the shortcut for $this.property in instance methods.

It's possible but counter productive
since: if you switch off journal this get's logged in Audit and generates at least 1 entry in journal
and swicthing it back on for the rest of your application you get another entry.

I just don't recommend things with negative impact on performance. 

Anyhow IF you insist it's your fate:

You may do it as well with SQL

For Regex you have 

$LOCATE

$MATCH

YES,  map it to a namespace where Journal is disabled

switching on/of journalling at every write is overhead and fills the audit log that is journalled itself

Dashboards are always fresh calculated.

Compare the performance in .NET  to  IE.  It should be rather close to each other being based on similar technology.

If there is a significant difference then you dig at  .NET end (buffers, ...)

If Chrome is significant faster then IE it's most likely the faster JS engine in Chrome.

Next you could look into global buffers of Caché and concurrent use of the Caché instance.
And (rarely) the complexity of your dashboard
 

you insert the object to itself ????

do context.MainObj.IssuesList.Insert(context.MainObj)

really ? does this make sense ??

I woldd expected something like:

do context.MainObj.IssuesList.Insert( tmpObj )

or

do context.MainObj.IssuesList.Insert(context.tempZenObj )

But there is no case where it is used.

Looks like "reserved for future use "

The diagramm shows to me  2 object REFERENCES (oref)
oref consists of a  (local) integer@Classname  and points to an object.
in your case both are of type %Collection.ListOfObj 
by the reference you can't tell that this is the same.
any ##class(%Collection.ListOfObj).%New() will create a new oref
in your case I see a count of 1 and then a count of 2 
you should look what happens in or after (19)  and in or after (29)
looks to me like a fresh return value

set CountRow=pObject.IssuesList.GetAt(i).Count()

you assume pObject.IssuesList.GetAt(i) gives back a %Collection Object (Iist, Array, ..)
Before applying method .Count() you should check if this assumption is true.

your previous description with ASSIGN / APPEND wasn't that convincing that you always have the object you expect.

ref: "out of the scope of ENSEMBLE to an external class" 
you should save anything that you want to keep over that call in one/multiple property of %context Object.


 

Looks like running the query but not getting a resultset.
You seem to be reading past the last row you got.
Hardcore fix, if noting better. Wrap it in Try {  } Catch {}   /// it's not my favourite

 

Then that's the curse of $PIECE() with no chance to fake it.

So name the separator   # ' " . / \ ~ ^ ...anything but ,

[ as Johnny Cash was singing:  ... anything but "Sue" ]

start here
it might not be as trivial as you think

to work down a collection of varying number of elements I'd use this kind of loop
in this case it's a double loop

This is the paranoic version!
If you trust ENSEMBLE you may skip the check for $IsObject()

this could have been what you were looking for.
it's pure CSP.

sorry, was in the wrong context before

online docs don't give a direct hint.

so my shot from the hip: 
selection expression - $select(), $case()  where you get a value based  on a condition
data expression - anything that sets, modifies, composes data.

this is  a quite academic view since  data expressions may contain selection expressions
and selection expressions may contain data expressions.
both variants and any mix of it  are quite common in COS
