Modify custom component from vm2 to vm3

[pm4698]

Hello there.

I created a custom vm2.6.12 component and now i am trying to move to vm3 with Joomla 3.

I made some modifications to custom component coding in order to match the vm3 format. Now, when i try to access my component from backend with debug enabled i see this error:

Strict Standards: Declaration of VirtuemartControllerSpecial::display() should be compatible with that of VmController::display() in ..\administrator\components\com_virtuemart\virtuemart.php on line 38 Strict Standards: Declaration of VirtuemartControllerSpecial::save() should be compatible with that of VmController::save() in ..\administrator\components\com_virtuemart\virtuemart.php on line 38

I have attached vm2 where all files of component are there in administrator folder and in vm3 are the files i have "upgraded" to match vm3 criteria. Any idea would be much helpful.

Thank you in advance

it saying that your functions should use the same parameters

e.g. in VM3 display is

public function display($cachable = false, $urlparams = false)

oh ok! Do you know vm3 parameters for save function also?
