[LON-CAPA-users] How to automatically display solution for a problem?

[Justin Gray]

Here is a sample problem that uses a block for after solved:

<problem><startouttext />Enter the correct answer 42 to see the hidden text
or image:<endouttext />
<numericalresponse answer="42">


    <textline readonly="no" spellcheck="none" />

</numericalresponse>
<solved>
    <img encrypturl="no" /><startouttext /><p>Hooray!</p><endouttext />
</solved>
</problem>

Note that the solution could be, for example, a text/HTML block or an image.
