Issue with create folder dialog in commerce area

Hi,

I have overlaid the create folder dialog to, under a certain path, create a new property for the folder, and have that property's value automatically generated when the folder is created. This was done with a taglib that is called only called under a certain condition (using a granite rendercondition so that this only happens under that path), and it generates a random number that is assigned to that property of the created folder.

This method has worked for the most part, but I have noticed that, if I create two folders in the same location, the taglib is only triggered the first time. If I refresh the page between creating the folders, there is no problem. If I create a folder and then a subfolder, there is no problem. But if I create two folders in the same location, only the first gets that randomly generated number in that property. Does anyone have an idea on what might be the reason for this? Thanks!
