XPath usage - Form save data

[achugh]

We have a complex java object with a structure define below.

Class A{

private String a;
private B b;

}

Class B{
private x;
}


and the data-source field defined on the client side as

<fields>
<field>
<name>a</name>
<title>a Title</title>
</field>
<field>
<name>b</name>
<title>b Title</title>
<valueXPath>//B/b</valueXPath>
</field>
</fields>

When we call save data on the form, the java object is populated using the following operation.

A a = new A();
dsRequest.getDataSource().setProperties(dsRequest.getValues(), a);

The field a of class A is set but not field b. How do we set the field b of type B ?

Thanks,

Bad XPath - such an XPath will always select any instance of B, not the instance of B underneath the current record. Remove the "//" and please refer any XPath tutorial before attempting to use it.

We have used different options like

1. <valueXPath>B/b</valueXPath>
2. <valueXPath>//B/b</valueXPath>
3. <valueXPath>B//b</valueXPath>
4. <valueXPath>//B//b</valueXPath>

but none of them worked for save operation.

Yes, those are all wrong. Again, you should probably read about XPath and JXPath before attempting to use the feature.

I translated the example incorrectly from actual source code. I meant it to be like below.

1. <valueXPath>b/x</valueXPath>
2. <valueXPath>//b/x</valueXPath>
3. <valueXPath>b//x</valueXPath>
4. <valueXPath>//b//x</valueXPath>
