I really need your help on this topic (http://community.qlik.com/message/325846#325846).
I am not able to get maps on the QlikView in addition I have a this complex requirement.
Can you help.... ?
Just installed IE9, running QV11SR1, Win7 64-bit, downloaded the attached sample and extension and it worked fine.
Try to turn of web view, remove the map, save, turn on web view and add the map again. Seen that error before with other extensions but never tracked down the root cause.
Edit: Oh and if you have UAC turned on you might need to run QV as administrator.
I am running IE9, QV11SR2, Win 7 64-bit.
The cluster map works on the QV Client but not on the access point.
Read that it only works with AJAX Client & not IE Plugin (which is what I have selected when loading the model via the access point).
We installed the extension on the QV server as well (where the live model is) and ran the GoogleMaps - Cluster.qar with success.
When you select AJAX the object does not show at all, when you select IE Plugin the object is there but it says"unknown chart type"
Otherwise the extension works beautifully but only on the client and not on the access point. Please help if you can.
I've tested this in two app's, one it works fine, the other I get the following error (it's actually the same error and same app I have the problem with for the markers as well):
Stack Overflow at line 24
The first app is a small dataset (under 10,000), the second app is larger (about 150,000), however I have cut it down to under 10,000 and still get the error ..
Any ideas? By the way, I'm good at Quality Management as I invariably break stuff!!
I havent tried it with that large dataset but I have seen the stack overflow error before, usually when u add the extension for the first time and there is no valid coordinates as a dimension. A F5 will fix that.
Is your data set clean? It could be that it snuck in some crap data amongst the coordinates that throws the stack overflow error.
If you can share the data, just email me offline, I can try to debug it.
I'll add the possibility to use custom marker icons while I'm at it. I'll do some test to see if I can validate the data input also without a too big performance hit to avoid further problems.
Re: Google Maps - Cluster
Thanks Alexander .. I tried the F5 and still getting the error - also, I'm down to under 700 records .. I do have a couple of other extension objects on their .. I wonder if this is causing problems.
Ok, so have taken off ALL other extension objects, cut down data and tried again and same error .. I even cleaned the entire cache .. very strange .. especially as it's fine in my other app .. If it's ok, will send you a copy - it's something for demo.qlikview, so don't want to post it here till it's complete ;0)
I have installed IE10, running QV11SR1, Win8 64-bit. In 2 apps (1 - about 1000 coordinate pairs, 2- 5 coordinate pairs).
2nd app works fine, but using 1st app I get stack errors (as jgo writes): Stack Overflow at line 24, Stack Overflow at line 25, Stack Overflow at line 27.
Do you have an opinion on the reasons?
Ye we found the issue. If you get emtpy rows in your data model for lat/lng that will throw the error.
I'm gonna add in default suppression of NULL rows for the dimensions and validation of the coordinates so any "crap" data is filtered out. I'll upload it later tonight for you.
Re: Google Maps - Cluster
Updated the original post with a new version of the extension.
- Now suppressing NULL rows to avoid Stack Overflow errors. The extension will still throw an error if you have coordinate pairs that's not valid, i.e bad data quality.
- Added an option to allow popup windows when you hover over an marker. The value in the infowindow is controlled by your expression. You can style the contents by regular html tags. Example:
='<B>Total Number of Visits: </B>' & Sum(CountVisit) & '<img src="http://www.bhsah.com/wp-content/uploads/2010/01/happy-cat1-150x150.jpg">'
- Worked around a bug in the SelectRow method so now when you select a marker that share latitude with other markers it will work.
- Moved over to a newer version of markerclustererplus.
