I would consider Ernestos notice as very important...

you should rather set:

plugin.tx_myext_pi1.my_cObject = WHATEVER
plugin.tx_myext_pi1.my_cObject	{
	...
}

And then use lines like:

$myClass = $this->cObj;	// Create copy of local cObject
$myClass->start($whateverRowOrArray);	// Fill the cObj ->data array
$content = $myClass->cObjGetSingle($this->conf['my_cObject'], $this->conf['my_cObject.']);	// Render the cObject


Especially note the 2nd line where the ->data array get's filled. You should pass "the row"
for which you are rendering the cObject (or $this->data of the pi1 FE plugin - but normally
the cObj is already instantiated with the data from there) to the ->start method.

With this usage the cObject get's a MUCH broader usefullness ... as you can access every field
in the actual row (which you passed) using the .field operator in stdWrap for example.

Example:


plugin.tx_myext_pi1.my_cObject = TEXT
plugin.tx_myext_pi1.my_cObject.field = keyInArrayPassedTo_start

which will render the value of the specified field.

Bernhard
