格式错误的表达式：尝试从哈希图检索值时出现“错误”

Question

I am trying to initialise the value of X to be the value of a hashmap.

Using the the IDE debugger , I can clearly see that the key-value of the hashmap has been initialised

However when i hover over the value of "secondcol" , i get the following

I don't understand how it is that the hashmap shows that the value has been initialised however the "secondcol" shows a malformed expression.

Moving on to the next step will cause a Null PointerException Error

What is happening and how do i resolve this issue ??

Answer 1

From the debugger it looks like the code should be

=CurrentPeerNode.ftable.table.get(i).value.secondcol

and

=CurrentPeerNode.ftable.table.get(i).value.thirdcol .

(You were missing the .value)
