get webResource in plugin

Hi,

I what to get one of my webResource in the plugin.

There any way to do it?

If not maybe someone has any idea to solve my problem:

I am in one entity. and on save I want to create a record of another entity.

But in the another entity I have a look up to my first entity.

My problem is: that when I want to put the one entity's guide in the look up -

his value is null. ( because that it happened on save ).

I will be happy to hear answers to this problem.

thanks!!
