WorkWithPlus has the possibility to include "Column Filters" within the grid's columns in order to filter data:
In some situations the "Columns Filter" may show the "Loading Data" message instead of displaying the data properly:
These kind filters are developed by using procedures (<TRN_NAME>WWGetFilterData) exposed as REST services, so you should try the following steps in order to solve the issue.
Step 1 - URL Rewrite (only for .NET)
You should verify that URL Rewrite is properly installed as explained in: https://wiki.genexus.com/commwiki/servlet/wiki?14958,How+to+install+URL+Rewrite
Once you install it, you have to allow WCF HTTP as explained here: https://wiki.genexus.com/commwiki/servlet/wiki?18398,URLRewrite+-+Common+issues,
Step 2 - Generate the procedures
If the problem still happens, open the procedure "<TRN_NAME>WWGetFilterData" and use the option "Build With This Only" in order to ensure that the procedure is being properly generated.
Step 3 - Use browser console
Use the browser console in order to identify the error and send an email to email@example.com showing the browser console data.
