<div dir="auto"><div>What I'm trying to do: add an MFNode or SFNode typed field to a ProtoInterface with addField(). If this is not the right thing to do, let me know. Apparently, when you add the field, it validates it, then calls setValue. SetValue is not the right thing to call for a SFNode or MFNode, afaik.

Are you requiring the Java 8 syntax for X3DJSAIL application programmers? Thanks!<br>

No restrictions. The declarative approach is an interesting style and no backwards compatibility with classical programming practice is sacrificed.<br>
<br>
also: Thank You for continuing reports such as the following, John. i first need to get out of "tall grass" of DOM + Java Reflection but will keep getting back to these and sorting each one out, they are very important.<br>

*Subject: *X3DJSAIL. Use of fields in ProtoInterface. addField() no longerworks.<div class="quoted-text"><br>
<br>
Please provide example of calling setChildren() with multiple field objects, or perhaps allow addChildren(). Haven’t spent too much time on this, addChildren() may work. Perhaps fix addField() to allow MFNode and SFNode, or remove from API?? Have validate call setChildren or addChildren for MFNodes and SFNodes? Many choices here. Modify fieldObject to not throw an exception of addChildren() is called on fieldObject?<br>

preliminary answer: please see the HelloWorldProgram.java for many example invocations.<br>
<br>
secondary answer: the pre-existing Java SAI interfaces are sometimes more restrictive that we might hope. Working document to keep track of issues at<br>

third answer: have been experimenting with JSAIL utility methods, such as pipelined addChild which can be easier to use sometimes.<br>

not quite understanding what you are trying to do here...<br>
<br>
suggested approach:<br>
- you will hopefully find an existing pattern (or TODO comment) in HelloWorldProgram<br>
- show regular-encoding version of your goal scene for understanding (.x3d or .json or .x3dv or .wrl)<br>
- let's build the java manually to match, once understood then go for the pattern<div class="quoted-text"><br>
