4.12.16 p:group

The p:group element acts as a container for other instructions. It allows to distinguish between e.g. different queries or navigation tree results if you would have more than one of them.

4.12.16.1 Request

Syntax:

<p:group id="expr" catchErrors="true|false">

 [... child instructions ...]

</p:group>

The id attribute is required.

The catchErrors attribute is optional. When this attribute has the value true, any errors that occur during the processing of the children of the p:group element will be caught. The result will then be a p:group element with an attribute error="true" and as child the stacktrace of the error. When catchErrors is true, the result of the execution of the children of the p:group element will need to be buffered temporarily, so only use this when you really need it.

4.12.16.2 Response

A p:group element with id attribute, and contained in it the output of the child instructions.
