I am trying to override processElement() of KeyedProcessFunction class. ProcessElement has 3 parameters and one of a parameter is context object. When I tried to retrieve timestamp from context object, it throws null pointer exception.

A line which throws null pointer exception in First example code is

current.lastModified = ctx.timestamp();

Second Example: Example 6.5 of "Stream Processing with Apache Flink" book.

I have two ValueState variables declared in a class which extends KeyedProcessFunction class. When I tried to retrieve the last value updated in the state, it returns a null value.

A line which throws null pointer exception in First example code is

Double prevTemp = lastTemp.value(); if(prevTemp==0.0 || r.temperature < prevTemp) {}

I have a JavaScript timer here, and I am trying to remove the white-space around the numbers so that the entire timer is green.

Operating system is QNX 6.6 (Posix 1003.1)

For the code below, the system log output contains only "Logger received USR2 signal".

I'm currently trying to make a total string depending on what radio buttons and check boxes I've selected (concatenate).

I have 2 radio button groups and one check boxes group; one of my radio groups is working perfectly fine, the other one though, selects automatically a value without my call and for the check boxes, when I select one, they all get checked..
