Changing zoom property on a googlemap component

[michael kenny]

i am using a google map component in my app and its working fine. but i wanted to hide the map and get it to appear when i click a button. The hide works fine. using the on click change property visible the map reappears but the zoom is wrong. i tried to add another on click change property event but cannot specify a value for zoom. tried a number 14, tried a string '14' tried a local variable but when i click the button i get invalid value.

is there a format to specify the zoom or am i missing something else?

thanks in advance

Hello Michael!

Multiple Event http://docs.appery.io/documentation/a... may cause it.
Testing it, I'll update.

(The solution is to use service callback events to invoke the next service - url not found: http://docs.appery.io/documentation/a...)

Just to reiterate. The map is working fine, when i just display it on page show. I wanted the map hidden and then visible on the click of a button. used the click set property event on the button and got the visible to work fine. However it was not zoomed in (after it becoame visible) as it was before i hid it. I tried the set property event for the zoom property but get this error
Uncaught Error: Invalid value for property < zoom : 10

what i need to be able to do is change the zoom on the map that i just made visible.

hope this is clear.

You can use Google Map API to control the zoom .

but. if i don't hide the map it has the desired zoom setting from my creation. the problem arises when i hide the map and then show it using the click set property event. - i am trying to change the zoom to fix the problem that has arisen from making the map not visible.
i am using the property zoom from the drop down menu for the property on the click event. if the hide/show did not change my map i would not need to do this.
maybe the problem is with the hide and show but i would have thought that making it visible or not visible would not change the other properties properties.

I'm not sure why the zoom changes. To what zoom does it default? Try setting the zoom in your code and the refreshing the map.

moved the map to a new page and used a button to get there. it works fine now
