[TYPO3-irre] IRRE Problem with TYPO3 4.2 - unable to delete child records

[Jochen Rieger]

Hey IRRE-guys,

has anybody experienced the following:

I am not able to delete child records that are of type inline. I hit the 
delete button, click OK in the JS prompt telling that I'm sure that I 
want to delete, and then - seemingly nothing happens.

This is the JS error msg I get (in file jsfunc.inline.js (line 670)):

--snip--

Element.getElementsByClassName is not a function

deleteRecord("data[52][tx_irretutorial_1nff_hotel][1][offers][tx_irretutorial_1nff_offer][2][prices][tx_irretutori...", 
undefined)

onclick(click clientX=872, clientY=548)

  inlineRecords = Element.getElementsByClassName(objectId+'_div', 
'inlineRecord...

--snap--

I doublechecked this with the irre_tutorial extension where the same is 
happening.

Should I file a bug report @ bugs.typo3.org?

Regards,
Jochen
