go() query string repetition bug

[drone1]

I'm having an issue:

• Give an expressive description of what is went wrong

Before I realized I can just call FlowRouter.setQueryParam(), I was running code that repeatedly (in my case, each time I would click a button), results in the query string param 'test' being repeated on the URL:

const route = FlowRouter.current()
const qs = {...route.queryParams} // clone
qs.test = 1
FlowRouter.go(
    route.path,
    {...route.params},	// clone
    qs
)

Shouldn't this be like calling setQueryParam()? Instead it results in the current path etc but adds ?test=1?test=1?test=1... to the URL. I would expect /path?test=1

@dr-dimitru hi, your commit generate a bug we have more than one parameter optional into pathDef.
Our pathdef : '/companies/:id?/:action?/'
When we call the path method : FlowRouter.path('companies', { id: this._id._str, action: mode })
the generated path is no more correct : "/companies/6135cb32d14df059605901fd?%2F%3Aaction="

in 3.7.5 of the package the generated path is like this : "/companies/6135cb32d14df059605901fd/edit"

thanks for you return

Hello @zeearth thank you for reporting.

This case is part of the tests.

Can you post values of console.log({id: this._id._str, action: mode}) looking ant the generated path mode is null or empty string?

Hello @dr-dimitru

I saw your test, but my parameters are optionnal. I'm thinking problems come from the split on the '?' router.js:226 I think the split is done for separate uri and query string.
this._id._str is a common mongodb id string "629f87f44ec0e563c4d5c458" mode is a string view or edit.
