Variables not working after upgrading to 5.1.0

[davinishi]

We've just upgraded the plugin on our server, and now almost all the dashboards are broken.

While trying to fix the issues, I discovered that the syntax has changed. Previously, we could use $variable, but now it seems we need to use ${variable}

However, this syntax doesn't work for attributes, only elements. For example:

This works: mypiafserver\${database}\${element}\child element ${somevariable};attribute x

This doesn't work: mypiafserver\${database}\${element}\child element ${somevariable};attribute ${attributevariable}

This also doesn't work: mypiafserver\${database}\${element}\child element ${somevariable};${attributevariable}

Is it a bug or something that we can fix/adjust? Also, is there a quick way to fix all the dashboards to adjust them to the new syntax or I will have to go one by one?

Obs: We are using the plugin to connect to the AF Server. I recall that someone else encountered a similar issue related to PI Point, which might be the same problem or a different one.
