Can't enter Grep expression field

[TheDauntless]

I might be using the extension wrongly, but here are my steps:

• Install Replicator
• Put in tester mode
• Go to http proxy history and select a request/response
• Right mouse button -> send to replicator

Now, when I click the "grep expression" field, I can't enter anything. The field is enabled ("grep expression is selected"), but I can't enter a value:

My mouse is on top of the field, but I don't get a cursor, and I can't tab to the field.

No output in the plugin's output window.

This might be related to the fact that it is sometimes not possible to change the port of the proxy in Burp, probably when clicking through the interface too fast. In that case, I can solve it by closing the proxy settings window and opening it again, but for your plugin, that's not possible.

Hi,

I am getting the same issue. This is also the case when macro has been added for authenticated tests.
So not able to add or select Expression' to validate vulnerability status.

Not Sure if any specific changes required prior to this.

Please can you try switching to Developer view, then back to Tester view? If that doesn't help, try switching detection mode to Collaborator, then back to Grep expression. There must be some slight unreliability in the code; I'll see if I can track it down. Also: does this occur consistently, or only sometimes? What OS and Java version?
