    <p>I'm Developing an chrome extension and encountered an problem i cannot solve ;/</p> <p>I wrote the manifest file and some java script code. Everything is working good except buttons. When I click them they should fire the echo function with an parameter and send it further to a plugin developed in firebreath. When I inject code manually in a html file everything is working fine but when injecting the code through javascript chrome console gives me an message that echo function is not defined. I tried several ways to inject the code but none work. </p> <p>So I ask for help or some good advice fellow programmists.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
