What is the difference between ${…} and !{…} in the Spark View Engine?

What is the difference between ${...} and !{...} in the Spark View Engine?

There probably is a really distinct difference between the two, but I see them used interchangeably.

Does one encode the output and the other doesn't? Which I have seen some discussion about in the groups? If that is true then what does this do:

${H(Model.Name)}

Also how will setting the following in the config effect ${} and !{}?

<pages automaticEncoding="true|false" />

I am hoping to document this for others as well, because the current documentation seems fragmented and out of date.

回答1:

!{...} never encodes, ${...} obeys the automaticEncoding setting and H(...) will always encode.
