Sitecore placeholder settings rules with dynamic key placeholder

[selketjah]

Hi

I have installed your package within a sitecore 7.0. With the normal sitecore placeholder, everything works great! (thx btw)

But I also use dynamic key placeholders within my project. After installing the package, in the page editor mode, the allowed controls are no longer pre selected as with the normal sitecore placeholders.

could you please assist me?

Thank you!

With kind regards Verschatse Gien

Thanks for the report!

Which flavor of dynamic placeholder are you using? (I've seen two or three different solutions). I haven't tested this with either Sitecore 7 or dynamic placeholders yet, but would love to investigate.

Thanks!

Hi

thank you for the quick response!

I used a blog post on dynamic placeholders and adjust it to my specific needs. I attached my class.

If I can be of any assistance, please do not hesitate to contact me.
