Default value in Dashboard dynamic drop-down & hiding chart with depends

[ppatkar]

My Dashboard contains 4 inputs : 

Time , 2 Drop Downs ( One Static whose value changes Second Dynamic Drop Down query ) & lastly a free text input. I am trying to default by  Dynamic Drop Down to * (Shown as All to user) & free text input to *.

I need to show or hide the Stats header &  the Count chart based on whether user enters text in text input field. ( Hide Stats when value is not * ).  

I am having the below issues :

1. drop-down default value (*) in my Dynamic Drop Down is not appearing in my chart search .  selectFirstChoice field is appearing . However if I remove selectFirstChoice,  I see issues when I pick one value & then change stats drop down.

2. Chart gets hidden when I enter some text in text input , however when I remove the text , chart doesnt appear back unless I change the static drop down. 

Below is my Dashboard source :

1. drop-down default value (*) in my Dynamic Drop Down is not appearing in my chart search .  selectFirstChoice field is appearing . However if I remove selectFirstChoice,  I see issues when I pick one value & then change stats drop down.

-- This is still an issue .

2. Chart gets hidden when I enter some text in text input , however when I remove the text , chart doesnt appear back unless I change the static drop down. 

-- This has been fixed with the below latest.
