I have a very similar problem, i think this is an Firefox bug. I have posted it an i am waiting for an answer...
We have the next situation:
- page with an iframe.
- the iframe contents a function called f().
We want to load the iframe and execute a function inside iframe from outside iframe.
We follow the next steps:
Step 1 - Button "load div_content": Ok.
Step 2 - Execute function f()
Execute function from inside iframe: Ok.
Execute function from outside iframe: Ok.
Step 3 - View location.href of iframe: Ok.
From inside: Ok.
From outside: Ok.
And we go to the beginning:
Step 1 - Reload div_content: Ok.
Step 2 - Execute function f()
Execute function from inside iframe: Ok.
Execute function from outside iframe: ERROR.
Step 3 - View location.href of iframe
From inside: Ok.
From outside: ERROR.
The second time we load the div_content with the same code, the function f() inside iframe is not accessible.
If we load the div_content with the same code changing the name of iframe (idFrame, idFrame2, idFrame3,...) the first load works fine, but if we reload an ancient iframe the function inside iframe is not accessible.
