[TYPO3-dev] FlexForm Help

I didn't pay attention to that thread before. Yes, it is possible.

In the functions to populate your fields you receive a variable called 
$config. Inside this variable is the value of the flexform in 
$config['row']['pi_flexform'] (note that this assume that we are talking 
about a plugin and that you are using the standard pi_flexform for 
storing your data; if that is not the case, change the name of the field 
accordinngly).

You can then retrieve the content of the flexform as follows:

$flexFormContent = t3lib_div::xml2array($config['row']['pi_flexform']);

and then extract the value of your first field:

$value = $flexFormContent['data']['sDEF']['lDEF']['dynField1']['vDEF'];

HTH
