did some more test, changed Hyperlink to 

https://app2.clarizen.com/Clarizen/Ext/

made the parameter as 

WidgetObjectDetailsPage.aspx?wt=ViewObjectDetails&uid=9.633544.234274&wid=ijZM6UT9ikmMbRT_rwQvmA&pid=453.5725549.274345&urgs=1&vid=351.45541889.274345&doid=6.9601025.4345&el=0&CSig=8A016476D3B5FA2C05CB1D8F05F118CF3D8

Now the parameter is added to the tail of the hyperlink, however it seems that the system encoded some of the characters, for example ? becomes %3F, "=" becomes %3D. This made the hyperlink unusable.

How do I prevent the system from encoding the characters and just use the original character?

That's an interesting use case, it is correct that Joget encodes the characters so that values will be passed over correctly as a single parameter value. It did not expect the values to be chain of parameters and values.

I guess we can create another hyperlink action plugin without this line of code (line 137)

return (paramValue != null) ? URLEncoder.encode(paramValue, "UTF-8") : null;

thank you Walter. That explains.
